  • Nginx Server Block Not Working? - Already running other vhosts just this one not working

    - by daveaspinall
    Im running a Debian 6 LEMP server with multiple virtual hosts and everything has been fine for 5 or so sites. But I've just tried adding another but for some reason it's just not working. By not working I mean in Chrome I get the "Oops! Google Chrome could not connect to subdomain.domain.net" error. I've changed the domain for security to subdomain.example.com and the IP is masked. Hosts file (I have multiple sub domains): xxx.xxx.xx.xxx *.example.com *.example Server Block: server { listen 80; server_name subdomain.example.com; access_log /srv/www/subdomain.example.com/logs/access.log; error_log /srv/www/subdomain.example.com/logs/error.log; root /srv/www/subdomain.example.com/public_html; location / { index index.html index.htm index.php; } location ~ \.php$ { include fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; } } I've created the system link to the file in the /etc/nginx/sites-enabled/ directory and restarted/reloaded nginx. DNS seems fine: # ping -c 2 subdomain PING subdomain.example.com (xxx.xxx.xx.xxx) 56(84) bytes of data. 64 bytes from www.example.com (xxx.xxx.xx.xxx): icmp_req=1 ttl=64 time=0.035 ms 64 bytes from www.example.com (xxx.xxx.xx.xxx): icmp_req=2 ttl=64 time=0.048 ms Checking the file with cURL works: # curl http://subdomain.example.com HTML - OK Emptied browser cache but still no dice. Anything I'm missing? Like I mentioned, I have a few sites running fine on the server currently so php-fpm etc etc are working. Any help would be much appreciated! Cheers, Dave

  • Setting up logging for a remote backup script

    - by Brian Dainis
    So I wrote up a short script that I am planning to run via a cron job daily to package up my site files and send them to a remote location. I also plan to incorporate DB dumps, but I have not gotten that far yet. My issue today however is that Im am uncertain how to log the output of each command for errors, warnings, or other pertinent information the command may output. I would also like to install sometype of fail safe so if something goes horribly wrong the script will stop dead in its tracks and notify me via email or something. Ok the email thing is not as critical, but would be nice. Does anybody have any ideas for that? Here is what I have so far. By the way, both servers are CentOS 6.2 running standard LAMP. #!/bin/sh ################################# ### Set Vars ################################# THEDATE=`date +%m%d%y%H%M` ################################# ### Create Archives ################################# tar -cf /root/backups/files/server_BAK_${THEDATE}.tar -C / var/www/vhosts gzip /root/backups/files/server_BAK_${THEDATE}.tar ################################# ### Send Data to Remote Server ################################# scp /root/backups/files/server_BAK_${THEDATE}.tar.gz user@host:/home/bak1/ftp/backups/ ################################# ### Remove Data from this Server ################################# rm -rf /root/backups/files/server_BAK_${THEDATE}.tar.gz

  • 100% CPU when doing 4 or more concurrent requests with Magento

    - by pancake
    Currently I'm having trouble with a server running Magento, it's unbelievably slow. It's a VPS with a few Magento installations on it used for development, so I'm the only one using them. When I do 4 request all 2 seconds after each other I'm finished in 10 seconds. Slow, but still within the limits of my patience. When I do 4 "concurrent" requests, however (opening 4 tabs in a row, very quickly) all four cores go to 100% and stay there for like a minute. How is this possible? I know that there are a lot of possibilities here, so any tips on how to make an Apache/PHP server go faster are also welcome. It used to go a lot faster before, and I've also tried APC, but it kept causing problems (PHP errors, something with memory pools) so I've disabled it. By the way, the Magento cache is off and compiling is also off. I know this makes Magento slower than usual, but I don't think a 60 second response time is normal for any Magento installation. Virtual hardware: 4 Cores and 4096MB RAM Swap is never used (checked with htop) 100GB disk space, of which 10% is in use Software: Debian 6 DirectAdmin and apache custombuild PHP 5.2.17 (CLI) If you need more info, please tell me how to get it, because I probably don't know how. I do know how to use the command line in linux and the usage of quite a few commands, but my experience with managing a server is limited.

  • Site name questions [closed]

    - by avenas8808
    I'm creating a website on German cars. No issues with it, since it's basically a PHP site, and let's say for the sake of argument, there are no server issues. However, I plan to call it "autohaus" (well, for the sake of this scenario anyway, it's not its actual name) The site is not for commercial gain; it's a fansite. Legally, can I use a name for a website if it's a commonly-used one - "autohaus" appears to be this. There are other sites called "Autohaus" but could someone use a similar name for non-commercial, information/educational use? Basically, what's the copyright law for such a situation? Currently my site is only on localhost for now, but what if I did want to release it to the web? Obviously the legal issues have to be taken into account before the site goes live, but there's no Data Protection Act. etc. since it's not selling anything, and no-one's buying anything, and the pictures in it are being used educationally (but that's for another question entirely)] [NOTE: This question is on trademark/names etc. not domains]

  • Mac OS X - Time Machine backup fails verification - What can I do to save the history?

    - by usermac75
    Hi, How do I make Time Machine to make a new complete backup without losing older versions of backed up files? Verbose: I am using the Time Machine backup on my OS X (Snow Leopard) to backup the whole computer to an external drive. I especially like the "history", i.e. the feature that allows you to restore the older version of a file. Problem: I had some data corruption on my external backup drive, I repaired it with the System Tool for doing that, it found some faults. I had the disk tool repair the external drive. After that, the external drive was OK and I could use Time Machine again. I let Time Machine do one more backup. Now I made a verification according to http://superuser.com/questions/47628/verifying-time-machine-backups, namely along sudo diff -qr . $HOME/Desktop 2>&1 | tee $HOME/timemachine-diff.log However: After doing the command above, several differences and missing files were reported, approx. 200 files in sum. Whereas some of the missing files were cache or excluded directories, the differences do bother me, especially as some important documents from me are listed as differing. How can I make sure that the data on the external drive is synced correctly? Is it possible to have Time Machine to do a complete new backup without losing the history? Or to have Time Machine compare all files for differences and re-write all files that are different? Or can I set some flags on the files that do not match to have them copied again? (like the archive-flag in Windows/Dos). I'd rather not touch the files because I would like to keep the date of last change/date of creation) Thank you for your thoughts!

  • Exchange 2010 UR3 - customizing OWA logon page

    - by STGdb
    I have an Exchange 2010 UR3 deployment that I need to customize the OWA logon page for. I've created a new LGNTOPL.GIF file to replace the existing one in the folder: “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.3.158.1\themes\resources” When I bring up OWA, I still get the original “Outlook Web App” logo. I’ve searched and found a couple of other instances of LGNTOPL.GIF in the directories: “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.3.123.3\themes\resources” “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.3.146.0\themes\resources” “C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\Current\themes\resources” I’ve replaced the LGNTOPL.GIF file in each of the above directories but got the same results. I’ve tried clearing my browser cache and even using multiple browsers from multiple PC’s but the same results. I’ve even tried making my GIF file the same pixel size as the original LGNTOPL.GIF logo but still the same results. I’ve tried restarting IIS on the CAS server and restarting the server but same results. Has something changed with Exchange 2010 UR3 when trying to customize OWA? I don't see anything documented about any change to OWA customization. Thanks

  • Server 2012 - transparent SMB failover without shared discs, possible?

    - by TomTom
    here is the scenario - there is a small set (200gb around) of data that I HAVE to keep available. Those are basically shared VHD images that serve as master images for a lot of our VM's - they then run in differential discs off those. The whole set is "mostly read only". In more detail: A file that IS there and IS used will NEVER change. I may delete files (when absolutely not in use) and add new files, but a file that is there once gets read protection set and that it is until it is retired. Obviously, I need as much uptime as possible. SO FAR we run that by having this directory local on every Hyper-V server. Now I think moving this into our storage fabric. Due to the "it HAS to be there" I pretty much want a share nothing architecture. DFS would be perfect for this - a file never changes, so replication would work nicely. Folders could be replicated to a number of servers, all would reference them from there. Now, that hyper-V supports SMB that could be a good idea to isolate these on a number of servers - we try to move into a scenario where the storage is more centralized. Server 2012 supports always on shares, but it seems that this only works with a clustered disc behind. Is there any way around this for read only file stores? All documentation points to stuff like a shared JBOD - but that would leave me open for file system corruption. I really plan to go quite separately here, vertically - 2 servers, both with SSD only for this, both with their own 2000W separate USV, both with enough bandwidth to handle everything thrown at them (note to everyone tinking this is 10G - this would be SLOW and EXPENSIVE compared to a nice Infiniband backbone). The real crux is that this is an edge case obviously - as the files are read only once in use.

  • How to have LiveJournal delegate my OpenID to something else?

    - by T-Boy
    I understand that if I have full control over my domain, I can set it up so that I can delegate the task of authenticating to another OpenID service provider. The problem is, what I'd like to do is to get the LiveJournal server to pass the authentication to someone else, instead of having LJ doing it. Preferably what I'd like to do is get LiveJournal, when asked by a web site, say, "No, I don't do it anymore -- go to this address". The plan was that this address would then be in a domain I fully control, which then would pass it on to whichever service provider I choose. I don't even know if I've gotten my understanding of OpenID right, if all this shenanigans are necessary, if my question makes sense, or if it's even possible with a service provider like Livejournal. ETA: Doing a little more reading up, and examining the source for my LiveJournal user page, I note that this particular line in the file's <header> area: <link rel="openid.server" href="http://www.livejournal.com/openid/server.bml" /> I suspect that changing this will allow me to forward OpenID requests to whomever I wish, I think; so far so good. Now comes the hard part -- figuring out how to change all of that using LiveJournal's customization options, if that is at all possible (here's hoping I don't need to pay to get that functionality).

  • Linux iptables / conntrack performance issue

    - by tim
    I have a test-setup in the lab with 4 machines: 2 old P4 machines (t1, t2) 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t3) Intel e1000 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t4) Intel e1000 to test linux firewall performance since we got bitten by a number of syn-flood attacks in the last months. All machines run Ubuntu 12.04 64bit. t1, t2, t3 are interconnected through an 1GB/s switch, t4 is connected to t3 via an extra interface. So t3 simulates the firewall, t4 is the target, t1,t2 play the attackers generating a packetstorm thorugh (192.168.4.199 is t4): hping3 -I eth1 --rand-source --syn --flood 192.168.4.199 -p 80 t4 drops all incoming packets to avoid confusion with gateways, performance issues of t4 etc. I watch the packet stats in iptraf. I have configured the firewall (t3) as follows: stock 3.2.0-31-generic #50-Ubuntu SMP kernel rhash_entries=33554432 as kernel parameter sysctl as follows: net.ipv4.ip_forward = 1 net.ipv4.route.gc_elasticity = 2 net.ipv4.route.gc_timeout = 1 net.ipv4.route.gc_interval = 5 net.ipv4.route.gc_min_interval_ms = 500 net.ipv4.route.gc_thresh = 2000000 net.ipv4.route.max_size = 20000000 (I have tweaked a lot to keep t3 running when t1+t2 are sending as many packets as possible). The result of this efforts are somewhat odd: t1+t2 manage to send each about 200k packets/s. t4 in the best case sees aroung 200k in total so half of the packets are lost. t3 is nearly unusable on console though packets are flowing through it (high numbers of soft-irqs) the route cache garbage collector is no way near to being predictable and in the default setting overwhelmed by very few packets/s (<50k packets/s) activating stateful iptables rules makes the packet rate arriving on t4 drop to around 100k packets/s, efectively losing more than 75% of the packets And this - here is my main concern - with two old P4 machines sending as many packets as they can - which means nearly everyone on the net should be capable of this. So here goes my question: Did I overlook some importand point in the config or in my test setup? Are there any alternatives for building firewall system especially on smp systems?

  • Cannot make bind9 forward DNS query to subdomain unless recursive enabled

    - by PP.
    I am trying to develop my own dynamic DNS. I'm running my own custom DNS for the subdomain on port 5353. ASCII diagram: INET --->:53 Bind 9 --->:5353 node.js | V zone_files I have example.com. The node.js DNS is for dyn.example.com. In my /etc/bind/named.conf.local I have: zone "example.com" { type master; file "/etc/bind/db.com.example"; allow-transfer { zonetxfrsafe; }; }; zone "dyn.example.com" IN { # DYNAMIC type forward; forwarders { 127.0.0.1 port 5353; }; forward only; }; I've even gone so far as to add a NS in my example.com zone file: $TTL 86400 @ IN SOA ns.example.com. hostmaster.example.com. ( 2013070104 ; Serial 7200 ; Refresh 1200 ; Retry 2419200 ; Expire 86400 ) ; Negative Cache TTL ; NS ns ; inet of our nameserver ns A 1.2.3.4 ; NS record for subdomain dyn NS ns When I attempt to get a record from the subdomain server it doesn't get forwarded: dig @127.0.0.1 test.dyn.example.com However if I turn recursive on in /etc/bind/named.conf.options: options { recursion yes; } .. then I CAN see the request going to the subdomain server. But I don't want recursion yes; in my Bind configuration as it is poor security practice (and allows all-and-sundry requests that are not related to my managed zones). How does one forward (proxy) zone queries for just one zone? Or do I give up on Bind altogether and find a DNS server that can actually forward specific queries?

  • Hyper-V and attaching physical disks

    - by Mike Christiansen
    So, I'm looking at rebuilding my home server. My current setup is the following Windows 7 Ultimate 1TB Boot Drive (my smallest drive) Windows Dynamic Spanned volume, continaing 1x 1TB drive, 2x 2TB drives, totalling 5TB. I am upgrading to a hardware RAID controller, and I would like to run Hyper-V server core. However, I want to retain the ability to join my "file server" to a homegroup, so I must use Windows 7. I know VHDs can only be like 127GB or something, so I obviously need to directly connect disks to my Windows 7 machine. Here is my plan: Server Core 2008 R2 (Hyper-V) 1TB Boot Drive (storing VHDs for boot drives of VMs) - possibly in a RAID 1 with my other 1TB drive 5x 2TB drives (1x 2TB drive hot spare), totalling 10TB, directly attached to a Windows 7 VM, for use of homegroup for this array. In the past, I directly attached the windows dynamic volume to a Windows 7 VM, and performance was abysmal. The question is, with hardware RAID, will it really make that much of a difference? Server specs: Intel Core 2 Quad Q9550 2.83GHz Asus Maximus II Formula (PCI-E x16) 8GB DDR2 RAM PC2-6400 (Yes, I know its a bit out of date)

  • RHEL 5.3 Kickstart - How specify location of individual package in Workstation folder?

    - by Ed
    I keep getting "package does not exist" errors during the install. I made a kickstart ISO to create an unattended install of a RHEL 5.3 build machine for C++ software releases. It pulls the kickstart config file from our internal web server. This is handy; it makes it easy to test and modify without having to make a new ISO. And I plan to check it in to version control if I can get it working. Anyway, the rpm packages are located in two folders on the disk; Client and Workstation. The packages install fine for the ones that are physically located under the Client folder. It cannot find those under the Workstation folder such as as doxygen and subversion complaining that packages do not exist. Is there a way to specify the individual package location? # ----------------------------------------------------------------------------- # P A C K A G E S # ----------------------------------------------------------------------------- %packages @gnome-desktop @core @base @base-x @printing @development-tools emacs kexec-tools fipscheck xorg-x11-server-Xnest xorg-x11-server-Xvfb #Packages Located in Workstation Folder *** Install can not find any of these ?? bison doxygen gcc-c++ subversion zlib-devel freetype-devel libxml2-devel Thanks in advance, -Ed

  • Fresh install CentOS 6.4 64b with directadmin slowly consumes all memory and crashes

    - by Coen Ponsen
    Dear server fault community, This is my first question on server fault, i'm new to server (mis)configuration so please forgive me for asking something stupid :) I'm running Directadmin on a CentOS 6.4 64b with 4GB memory and over 10000Gh virtual machine. I migrated my websites because my former vps couldn't keep up anymore. Only half of the websites from this 1GB machine were migrated jet. So the migration is still in progress and already my server crashes every day. The server performance up until that moment is perfect. The directadmin log files show nothing out of the ordinary. Yesterday only the mysql server crashed but it also crashed the entire machine before. The memory usage in DA seems to be normal: directadmin directadmin (pid 3923 22158 22159 22160 22161 22162 )8.75 MB dovecot dovecot (pid 3851 ) 47.8 MB exim exim (pid 1350 ) 1.29 MB httpd (pid 21525 21528 21529 21530 21531 21532 21546 21571 21742 21743 21744 )490.4 MB mysqld mysqld (pid 1299 ) 287.8 MB named named (pid 3807 ) 16.3 MB proftpd proftpd (pid 1481 ) 1.91 MB sshd sshd (pid 1173 21494 ) 5.16 MB Restarting services immediately frees up memory, but slowly over time the memory usage increases(about 24 hours to crash). The commands: # sync # echo 3 > /proc/sys/vm/drop_caches Will free al memory correct. I could just create a cronjob but it seems the wrong way around to me. I can't seem to pinpoint the cause. Any advices, references or tips are highly appreciated!

  • Matched or unmatched drives for RAID arrays?

    - by Will
    Looking around there is conflciting information on this, with some strongly suggesting one or the other. From my understanding the issue with matched drives is that the wear on both drives is more or less the same, so the potential for the second drive failing with or very soon after the first is pretty high. People also claim matched drives give substianatally higher performance however assuming the unmatched drives are more or less the same (eg 2, 1 TB STATA II 7200rpm drives with 32MB cache), would the minor differences between say a Seagate and a Western Digital one (say one has a 128MB/s read rate, and the other a 150MB/s read rate, as well as I guess various other minor differences) actually cause any notable performance loss, ie potentialy worse than two matched 128MB/s drives, or does RAID not really care and give you essentially an optimal solution (eg upto 278MB/s total read speed for RAID 0 and 1) and similar for other RAID with more "unmatched" drives (5 and 1+0 come to mind as possibilities)? Also I couldnt find much info on how this is different on different RAID setups, eg RAID 0 or RAID 1, software or hardware RAID, etc. I'm assuming such things have an effect, and thats it's not all the same for RAID in general?

  • Server 2008 email on Event variables

    - by Jeff Miles
    One of the new features of Server 2008 is the ability to attach a task to a specific event in the event logs. One of the actions available is to send an email through a SMTP server. This is working great, however it would be ideal if in the message body, the Event contents could be placed. I have tried using $eventdescription and %eventdescription%, but those are just shots in the dark. Any amount of googling produces no results. Does anyone know if this is possible? Update: Sparks' suggestion below is a step in the right direction I believe, however that method doesn't seem to work for all values. For example, I can pull the RecordID, Severity and Channel as shown, but I can't use the same method to retreive the EventID, or most importantly the description. Here's the raw XML from one event: [Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"] [System] [Provider Name="DFSR" /] [EventID Qualifiers="16384"]4412[/EventID] [Level]4[/Level] [Task]0[/Task] [Keywords]0x80000000000000[/Keywords] [TimeCreated SystemTime="2009-05-14T18:18:09.000Z" /] [EventRecordID]45692[/EventRecordID] [Channel]DFS Replication[/Channel] [Computer]servername.domain.com[/Computer] [Security /] [/System] [EventData] [Data]9046C3F4-843E-4A53-B941-4B20764072E5[/Data] [Data]D:\departments\Geomatics\Plan Quality\Data Processing\CG3533017 2009-05-13 KT FIXED[/Data] [Data]D:\departments[/Data] [Data]{26D5F604-E603-4F87-8EC3-DE9A945DA8FD}-v927199[/Data] [Data]Departments[/Data] [Data]domain.ca\files\departments[/Data] [Data]B8242CE2-F5EB-47DA-BA5B-1DD2F7EE3AB9[/Data] [Data]DFAA7A54-66CB-4C31-81A0-0F861382C32C[/Data] [Data]CG3533017 2009-05-13-{26D5F604-E603-4F87-8EC3-DE9A945DA8FD}-v927199[/Data] [/EventData] [/Event] I have tried using a ValueQuery for EventData, but it returns no data.

  • is there a man in the middle attacking to my server machine?

    - by GongT
    My server works well about half a year. But a strange thing happened (several hours before). This server has two IP-address 58.17.85.19 & 117.21.178.19 When I navigate to http://58.17.85.19, nothing different as before. But http://117.21.178.19 will return a "302 Object moved" and become a "redirect loop" I do some test: ($cmd = "wget http://117.21.178.19/?xx=$RANDOM --max-redirect 0 -S --no-cache -O -") Step by step: run $cmd on my PC and my firend's one (we live in two side of China, far away). - got 302 run $cmd on this server - got 200 OK (content is correct result of index.php) run $cmd on another server in same computer room - got 200 OK telnet from my PC and build an HTTP request (type by hand) - got 200 OK shutdown php-fpm, run $cmd on my PC - got 302 run $cmd on server - 502 Bad Gateway shutdown nginx, run $cmd on both the server and my PC - Connection refused. create iptables rule, refuse any connection to 58.17.85.19:80. run nc -l 80 -k -vvv on server and run $cmd on my PC NC show me that.... Server accept connection (Connection from [my ip]) My connection closed ! (Remove fd xx from list) wget dump out response - got 302 I know that, normaly, NC will accept connection, then dump HTTP request from client, and client will wait for response. this connection will open forever(infact client will close connection becouse timeout), becouse NC can't give any response. So... where my request gone? who send an response to the client? some virus on my server system? If so, why 58.17.85.19 didn't has this error? or... I was attacked by a middleman?

  • torrent downloads not showing on Squid log

    - by noobroot
    hello, i have just a few months working as sysadmin, hence i still have lots to learn, first thing id like to do is as follows: We have an OpenBSD 4.5 box acting like firewall,dns,cache etc, the box has 2 network cards, one conected directly to the internet and the other to our switch, i used to work with sarg for the log analysis but then changed to the much faster free-sa. I use a daily free-sa report to check the bandwidth usage and report our top 5 bandwidth consumers (3 days a week being #1 and you will be buying the pizzas :D, we are a small company ~20 so we are very familiar). this was working really good until recently, one of us required to download some stuff via torrent (~3GB) and since the pizza rule is active for non-work related downloads, he told me (verified) that his download was indeed work related so i would dismiss that 3GB off his quota, but to my surprise the log didnt showed that 3GB, since his ip consumption was only around 290MB. More recently, since the FIFA world cup started, we know that some of the employees are watching the match's streaming, we know it and we dont care about it since, like already stated, we are a small company so we dont have restrictive policies, we all can chat, watch youtube, download anything we want BUT we are only allowed 300MB a day otherwise you'll get in the top5-pizza-board, anyway, that streaming consumption is also not showing in the free-sa reports. So my question is, why is these data being excluded from the reports? im thinking that the free-sa reports list only certain types of things but im also thinking if are the squid logs the ones that are not erm... logging these conections. Any help, guide, advice or clarification is appreciated.

  • How can I optimize my ajax calls to deliver at 60ms.

    - by Quintin Par
    I am building an autocomplete functionality for my site and the Google instant results are my benchmark. When I look at Google, the 50-60 ms response time baffle me. They look insane. In comparison here’s how mine looks like. To give you an idea my results are cached on the load balancer and served from a machine that has httpd slowstart and initcwnd fixed. My site is also behind cloudflare From a server side perspective I don’t think I can do anything more. Can someone help me take this 500 ms response time to 60ms? What more should I be doing to achieve Google level performance? Edit: People, you seemed to be angry that I did a comparison to Google and the question is very generic. Sorry about that. To rephrase: How can I bring down response time from 500 ms to 60 ms provided my server response time is just a fraction of ms. Assume the results are served from Nginx - Varnish with a cache hit. Here are some answers I would like to answer myself assume the response sizes remained more or less the same. Ensure results are http compressed Ensure SPDY if you are on https Ensure you have initcwnd set to 10 and disable slow start on linux machines. Etc. I don’t think I’ll end up with 60 ms at Google level but your collective expertise can help easily shave off a 100 ms and that’s a big win.

  • Lost Windows 7 boot after EasyBCD with EFI

    - by drent
    I've got a Lenovo Y580 with a 64GB SSD and a 1TB HDD setup using GPT and setup to boot from (U?)EFI. I was trying to get my Linux Mint installation on the Windows boot manager using EasyBCD (I didn't realise EFI but it wiped my boot partition/loader and I cannot seem to get Windows back (and I still can't get a bootable Linux Mint). Using the System Recovery utility, Startup Repair can't "see" windows (it might be because I'm using a 7 Pro disk to recover Home Premium?). In command prompt, Bootrec tools don't do anything and bootsect can't run because it says that it's for BIOS only and I've booted with EFI. I can see the EFI data on the 200mb SSD partition using diskpart but I don't know how to add Windows back onto whatever bootloader I have/need. At the moment the only options I can see are: Do a fresh install of Windows and hope that the setup remains as fast as the default one (the SSD is some kind of cache for Windows but I can't quite see how it works given that the rest of the SSD is unpartitioned space). This seems like overkill given that Windows was working fine til EasyBCD deleted it. Try forcing BIOS mode and see if that somehow magically fixes things Try converting from GPT to MBR to try and use the bootrec/bootsect tools (and maybe back again) which seems like a really bad idea. Anyone have any ideas?

  • WD Caviar Green Extremely Slow

    - by Steven
    I am encountering a really weird problem on my WD Caviar Green HDD. Well first of all I have 2 HDDs on my Desktop, one 160GB Seagate holding my Win7 Ultimate x64 and the problematic one, WD 1.5 Caviar Green for storage purpose. My problem is kinda weird, when I transfer files from my Seagate(C:) to my WD (D:) the speed is good (50-60MB/s). Then the problem arises when I transfer too "many" large files, the transfer speed would go straight down to kilobytes/s. Well after I cancelled the transfer and access my D:, even entering a folder requires loading for like 10 seconds. Such problem not only arises when I am transferring files to my D:, it seems like my WD can't handle much activities. For instance, last time I installed my game on D: and I would face much lag after playing for some time. When the same game is installed on C: no problem arises. Does anyone knows what is the problem? P/S: There was one temporary solution that I used to tried. After the "situation" occurs, I tried to access as many folders on D: as I can and let it load, repeating such actions and giving it some time bring the D: back to speedy transfer. However, large transfers would causes the situation to happen again. Does it have something to do with cache whatsoever?

  • Hard drive causing BSOD

    - by JoshIrving
    I've come across a problem after building my new PC and installing a clean Windows 7. I originally planed on a RAID 1 or 0 but after further research I decided against it. So I was left with two 1TB Western Digital Black SATA 6Gb/s hard drives. My plan now was to use my second hard drive as a backup (using Windows Backup or 3rd party software). I set both hard drives to AHCI in the BIOS and installed Windows 7. I went through the lengthy process of downloading and installing each driver manually (latest versions), using the motherboard disk for a list of what I need. After a few restarts and before installing any software, I took an image backup onto DVD and the second hard drive. First witnessed the problem during the first scheduled Windows backup. The progress bar froze at about 70% (doc backup done, image backup in progress). It stayed still for 2 hours until it blue screened. Next time the backup froze, I tried shutting down. It logged me out and got stuck at the last step ("Shutting down" and blue spinner) for an hour, until I hard shutdown. I later realised this hasn't got anything to do with the backup. I ended up blue screening on almost every shut down (same place). Turns out, it's because of the second hard drive spinning down or turning off. The computer will now shutdown properly, as long as I remember to read or write to the second drive before executing shutdown. I've now set "Turn off hard disk after: Never" - No problems, so far. Do I have dodgy hard drive(s) or should I investigate the POWER_STATE_DRIVER_FAILURE BSOD - can it be a driver issue? AHCI?

  • Blue screen of Death on Install

    - by Toby Allen
    I have a machine with Windows Vista Installed. It has an Intel X25 SSD as the System Drive I want to reinstall (I plan to format and overwrite Vista) with XP. When I boot up using the Dell XP CD it loads the initial drivers then i get a Blue Screen. This is quite concerning. The installed OS works ok, but its giving problems so I want to remove it. Should I just format the SSD and try again? Will this make any difference? Can I do something to avoid hitting the Blue Screen? Its possible I had corrupt sectors on one of the other disks, will a new XP install use the System drive or drive 0? Can I force the install to use a specific drive when installing? Error: *** STOP: 0x0000007B (0xF78D2524,0x0000034,0x00000000,0x00000000) I never did find the answer, however I removed the SSD and tried to install on other disk - CRASH I disconnected the other disk and tried to install with only SSD plugged in - CRASH I removed 1 block of RAM - CRASH I used a windows 7 CD - NO CRASH

  • Server 2008 email on Event variables

    - by Jeff Miles
    One of the new features of Server 2008 is the ability to attach a task to a specific event in the event logs. One of the actions available is to send an email through a SMTP server. This is working great, however it would be ideal if in the message body, the Event contents could be placed. I have tried using $eventdescription and %eventdescription%, but those are just shots in the dark. Any amount of googling produces no results. Does anyone know if this is possible? Update: Sparks' suggestion below is a step in the right direction I believe, however that method doesn't seem to work for all values. For example, I can pull the RecordID, Severity and Channel as shown, but I can't use the same method to retreive the EventID, or most importantly the description. Here's the raw XML from one event: [Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"] [System] [Provider Name="DFSR" /] [EventID Qualifiers="16384"]4412[/EventID] [Level]4[/Level] [Task]0[/Task] [Keywords]0x80000000000000[/Keywords] [TimeCreated SystemTime="2009-05-14T18:18:09.000Z" /] [EventRecordID]45692[/EventRecordID] [Channel]DFS Replication[/Channel] [Computer]servername.domain.com[/Computer] [Security /] [/System] [EventData] [Data]9046C3F4-843E-4A53-B941-4B20764072E5[/Data] [Data]D:\departments\Geomatics\Plan Quality\Data Processing\CG3533017 2009-05-13 KT FIXED[/Data] [Data]D:\departments[/Data] [Data]{26D5F604-E603-4F87-8EC3-DE9A945DA8FD}-v927199[/Data] [Data]Departments[/Data] [Data]swg.ca\files\departments[/Data] [Data]B8242CE2-F5EB-47DA-BA5B-1DD2F7EE3AB9[/Data] [Data]DFAA7A54-66CB-4C31-81A0-0F861382C32C[/Data] [Data]CG3533017 2009-05-13-{26D5F604-E603-4F87-8EC3-DE9A945DA8FD}-v927199[/Data] [/EventData] [/Event] I have tried using a ValueQuery for EventData, but it returns no data.
