  • NGINX rewrite for vanity URLs when file doesn't exist (try_files and rewrite together)

    - by user1721724
    I'm trying to get vanity URLs on my server. If the file path from the URL doesn't exist, I want to rewrite the URL to profile.php, but if my users have periods in their usernames, their vanity URL doesn't work. Here is my conf block. server { listen 80; server_name www.example.com; rewrite ^/([a-zA-Z0-9-_]+)$ /profile.php?url=$1 last; root /var/www/html/example.com; error_page 404 = /404.php; location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ { expires 1y; log_not_found off; } location ~ \.php$ { fastcgi_pass example_fast_cgi; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/html/example.com$fastcgi_script_name; include fastcgi_params; } location / { index index.php index.html index.htm; } location ~ /\.ht { deny all; } location /404.php { internal; return 404; } } Any help would be appreciated. Thanks!

  • Browser says "Waiting for www.xyz.com" for a very long time

    - by Phil
    When I load my website (hosted with Ipage). The browser often takes an incredible long time saying "Waiting for www.xyz.com ..." before any elements of the site actually appear. After this "Waiting for" process, the text, images and everything else actually load quite fast. I contacted my host with my tracert result and they said they optimized my website database and increased the memory available to PHP on my account to 64 Mb.They also said they have checked the issue by accessing my website and found that it is loading fine without any slowness. It seems to be a temporary issue. Please try to access your website with different browser and network. I tried different browsers and networks but this "Waiting for" process always takes too long. My website is http://www.surreyextra.com/ . It's Wordpress and BuddyPress. I'm in the UK while Ipage host is placed in the USA, can this potentially be a problem? I have tried a number of optimizations, like minifying my CSS and JS files and use catching but the problem hasn't improved. So is it my host's fault, should I contact them again?

  • Compaq motherboard CQ60 AMD - nvidia chipsed graphic problem

    - by Dritan
    Hi! It nice to have read that you solved this problem this way. I have 2 laptops Compaq CQ60 AMD Athlon with Nvidia graphic cards. the first one is new, when i press power button, it lights up only the ON led in front and nothing else, no fan working, blank screen, no beep.. I don't know what may be the problem. When I put on power adaptor, it lights up only the side power led near dhe power adapter plug but it doesn't light up the front led one. the second one have this problem that it spins the fan, light power and On led, but it doesn't show nothing on the screen blank (even with external monitor). In this case it maybe this problem of the Nvida Graphic Chip and it may need a reflow. I have an hot air station, but I don't know if I should try this or the oven one. Please can you give me any suggestion what to do to solve this. I have read that the solution of the Oven method is just temporary,maximum of three months, do you have the same experience about this? Any suggestion is wellcome.

  • running chkdsk /F on a large mounted NTFS image file gets BSOD (Windows Vista)

    - by Citizentools
    Using ddrescue, I've created ISO files from the C: and D: drives on my Windows XP laptop's harddisk (after the laptop stopped booting and chkdsk etc. wouldn't fix it). I was able to mount the 60 GB D.iso file use OSFmount, and successfully recreated the D: drive on another laptop. The C.iso image is more problematic. ddrescue left about 3mb unrecovered of 85 GB total, after multiple passes (no big worries about this) and I'm able to mount it with OSFmount on a Windows Vista laptop. However, when I run chkdsk /F /V on the mounted drive (which was mounted as H:), I consistently get a blue screen (BSOD). CHKDSK makes it through the first three passes, including index fixing and security descriptor fixes, without errors, but triggers a BSOD when it attempts to fix the volume records or bitmap If I attempt to fix the drive by clicking on Properties-Tools-Error checking-Check Now-Automatically fix file system errors, I get an alert box reading "WIndows was unable to complete the disk check." I'd try a tool other than OSFMount, but it's the only thing I've found so far that will mount large ISO files, and it has worked for me up to now in this process. [Update 2011-11-13 18:41 EST] Just ran the same process using the original Windows XP laptop, with a different internal drive, and chkdsk worked like a champ. So the question is still interesting, but decidedly less urgent.

  • Setting Up My Home Network

    - by Skizz
    I currently have five PCs at home, three running WinXP and two running Ubuntu. They are set up like this: ISP ----- Modem ---- Switch ---- Ubuntu1 -- B&W Printer | |--WinXP1 | |--WinXP2 Wireless |--Colour Printer | |---------Ubuntu2 |---------WinXP3 (laptop) The Ubuntu1 machine is set up as a PDC using Samba and runs fetchmail, procmail, dovecot to get my e-mail and allow me to access the e-mail via imap so I can read the e-mail on any PC. I'd like to set up the network like this: ISP ----- Modem ---- Ubuntu1 ---- Switch ------WinXP1 | | |--WinXP2 B&W Printer Wireless |--Colour Printer | |---------Ubuntu2 |---------WinXP3 (laptop) My questions are: How to configure Ubuntu1 to act as a firewall. How to configure Ubuntu1 to provide a consistant user authentication across the network, at the moment Samba provides roaming profiles for the XP machines but the Ubuntu2 machine has it's own user lists. I'd like to have a single authentication for both XP machines and linux machines so that users added to the server list will propagate to all PCs (i.e. new users can log on using any PC without modifying any of the client PCs). How to configure a linux client (Ubuntu2 above) to access files on the server (Ubuntu1), some of which are in user specific folders, effectively sharing /home/{user} per user (read and write access) and stuff like /home/media/photos with read access for everyone and limited write access. How to configure the XP machines (if it is different from a the Samba method). How to set up e-mail filtering. I'd like to have a whitelist/blacklist system for incoming e-mails for some of the e-mail accounts (mainly, my kids' accounts) with filtered e-mails being put into quaranteen until a sysadmin either adds the sender to a blacklist or whitelist. OK, that's a lot of stuff. For now, I don't want config files*, rather, what services / applications to use and how they interact. For example, LDAP could be used for authentication but what else would be useful to make the administration of the LDAP easier. Once I have a general idea for the overall configuration, I can ask other questions about the specifics. Skizz I have looked around for information, but most answers are usually in the form of abstract config files and lists of packages to install.

  • Web page layout becomes broken when moved to live.

    - by Moses
    I want to preface my question with the fact that I'm only a front-end web developer, so please excuse my gross lack of knowledge in this area. My company has three webservers: one for development (IIS v5), one for staging (IIS v5), and one for live deployment (IIS v6). Staging is an exact mirror of live. When I compare the staging and live web pages side by side in Firefox (3.6), the pages are identical. However, when I compare the staging and live pages with Internet Explorer (8), there are major differences... In staging, the squares for bulleted lists are small. In live, the squares are big. In staging, the borders for tables are thick. In live, the borders are thin. In staging, an ASP generated image is the proper height. In live, the image is cropped at the bottom by about 10px. In the end, the layout on live became broken because of these tiny differences, but why? Does the fact that live is on IIS 6 and staging is on IIS 5 account for the small variance in display? And is there any way I can change this server side? Also, is there any reason why Firefox displays both correctly and IE displays both incorrectly?

  • Installing Windows Management Framework 3.0 basically destroyed WMI, how can I fix it without reinstalling the O.S.?

    - by Massimo
    Related, of course, to this question. Before discovering it was somewhat... dangerous, I installed Windows Management Framework 3.0 on a number of Windows Server 2008 R2 SP1 servers, and WMI got completely trashed on all of them. This is what the WMI namespace looks like on a normal server (this is from Server Manager - Configuration - WMI Control): This is what it looks like after installing WMF 3.0: Yeah. Everything except WMF 3.0's new features is gone. Needless to say, nothing seems to work anymore on those servers. And no, this is not due to some strange installation error, this happened on three servers which were perfectly working before installing WMF 3.0, and on all of them the installation completed succesfully. Admittedly, one of them had a somewhat complex setup (various System Center products and SQL Server instances)... but two of them are just plain standard domain controllers which do nothing else at all. How can I fix this mess without having to reinstall the O.S. on these servers? And why did it happen in the first place?

  • Wireless card on HP laptop not working

    - by D. Strout
    I just bought an HP Envy m6-1125dx online from Best Buy. When I got it home and started it up, the wireless card did not work well - at all. I could connect, but any real usage would cause the connection to start dropping every 30 seconds or so, and it would be really slow. Taking another look at the reviews on the Best Buy site, it seems only a few others had this problem, so I took it to my local Best Buy and exchanged it for another unit. Got it home again and the card had the same issues. Which leads to my dilemma. First: does this model have several different cards that it could come with? Mine is a Ralink RT5390R (on both units I received). If it does, then I can keep exchanging until I get a unit with a different card. I wouldn't ask this, except it seems weird that only a few people mentioned this issue, so I thought that might be one possibility. I looked in to replacing the card with a different one myself, but it seems that HP blocks certain wireless cards. However, some people reported success in replacing the card, and this site said it was only an issue on "older HP computer[s]". Can anyone confirm this? Finally, if that fails/will not work, does anyone know what I can get through Best Buy? I am concerned that they will not put any different card than the Ralink, and after two of those, I don't want that. Can I ask Best Buy support to use a different card? Can they even get another card from HP? I guess the base question is: should I attempt to replace the card myself (two days via Amazon to get a new card), should I try to get the laptop repaired through Best Buy (two - four weeks), should I go for a different model laptop from Best Buy, or should I try a different unit of the same model (three's the charm?).

  • Relation between server_name in nginx sites-available, /etc/hosts file and A-records

    - by user2818584
    I have the following two server-blocks in my config-file in sites-available: server { listen 80; server_name www.mydomain.be; root /usr/share/nginx/html; index index.html index.htm; location / { try_files $uri $uri/ =404; } } server { listen 80; server_name sub.mydomain.be; root /usr/share/nginx/sub; index index.html index.htm; location / { try_files $uri $uri/ =404; } } I also created an A-record for both www.domain.be and sub.domain.be with the IP of my server as value. Yet, when I try to reload my nginx configuration with service nginx reload it fails. When I remove the second server-block, it reloads as expected. I know this topic is popular, and that there are loads of such [nginx][subdomain] questions here, but none of them seems to discuss explicitly how the following three things hang together: virtual hosts or server blocks in nginx (est. server_name matching) the effect of A-records on how nginx processes requests the need to add hosts to /etc/hosts Right now I have the impression that a lack of knowledge of this bigger picture, rather than specific knowledge of nginx configuration prevents me from making this work.

  • New Static Website with Hosted DNS alternating 502, 503 and Page Does Not Exist Errors

    - by Dave
    This has become an increasingly frustrating ordeal. I'm mostly a web developer, so forgive me if I am using improper terminology here. I have a client that had purchased a domain at JustHost. We built him a website and have it on our own server space. Now, I'm mostly used to dealing with godaddy and it is simple enough to manage dns records and point the A record to our server IP, where Apache on our end deals with the domains via name-based virtual hosts. But for some reason, in setting this up with JustHost, when attempting to go to the domain name, I either get a 502 or 503 error or "webpage does not exist". Now, I know that the basic functionality of the webpage must be working because I can access the the index etc straight through my servers www data (IE [server-ip]/website_folder). I was on the phone with technical support for over three hours yesterday with justhost and the best I could get was "That's really weird..." I've checked my logs and there doesn't seem to be anything coming through to my end. Does anybody have an idea of whats going on here? I would love for it to be a problem on my end, because justhost doesn't seem capable of helping further. Any help is greatly appreciated, thanks. I forgot to mention that we have several other sites up and running and completely accessible.

  • it opens "open with" prompt whenever scheduled task run

    - by Shashwat Tripathi
    I am trying to run a .vbs file on every five minutes. I am trying to do this using windows task scheduler. In Actions tab - New Action, I select the file ("D:\Documents\FC3 Savegames\FC3.vbs") using open file dialog I have made all other setting properly. But whenever the task begin, It opens open with dialog every time. Once I choose Notepad to in open with dialog. Then Another dialog opens from Notepad saying Can not find D:\Documents\FC3.txt file. Do you want to create a new file with three buttons Yes, No and Cancel Help me what is wrong. I feel that white spaces in the file path causing the problem. Added later Well I just fixed this by setting path to shorthand ("D:\Documents\FC3Sav~1\FC3.vbs"). But it still opens "open with" dialog everytime. Now it has two main programs saying "Keep using Microsoft Windows Script Host" and Other Program. This dialog does not open when I run vbs file directly.

  • linux: mount old ATA disk to USB adapter

    - by 130490868091234
    I am trying to recover data from an old Linux that was installed in a computer on an ATA hard drive. I found a ScanLogic Corp. SL11R-IDE IDE Bridge (04ce:0002), an ATA adapter to USB 1.0 like the one in the picture: and after switching it on, I plugged it into a laptop with Ubuntu 12.04. I am used to the drives being automatically mounted, but this one doesn't show up in /media. After doing a dmesg, all I got is this: [215298.671924] usb 2-1.1: new full-speed USB device number 5 using ehci_hcd [215298.767330] scsi19 : usb-storage 2-1.1:1.0 [215299.841701] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.017258] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.197050] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.372730] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd I tried plugging in the adapter to the three different USB ports in my laptop (one of them USB 3.0), but got no luck with any of them. I get different devices under, for example: /dev/bus/usb/003/002 or /dev/bus/usb/002/004, but I don't get any /dev/sdbN links. The output blkid -o list -c /dev/null is just the laptop's partitions. I have tried taking out the jumper, putting it as master and as CS Enabled, but didn't change the result. Any ideas?

  • (Mac Intel) HP PS driver prints in B&W from Adobe Reader after installing Cannon PS driver

    - by John B
    I have a unique problem that leaves me at a loss as to where to start troubleshooting. We have three Macs we use for graphics, two of which are PowerPC and one which is Intel. They are set up to print to an HP 5500dn, but occasionally this printer gets tied up with a massive print job, so I installed the PS driver (iR-PSv1.81MacOSX) for the Cannon C3200 Printer/copier on each of the machines. Both of the PowerPC Macs installed without issue, but the Intel Mac exhibits strange behavior: I've confirmed that while the Cannon driver is installed (whether or not the Cannon is set up for printing in print settings), the HP 5500dn will print in color from Safari, but only prints in black and white from Adobe Reader. The Cannon printer itself has not exhibited any strange behavior As soon as the Cannon driver is uninstalled, the HP 5500dn prints in color from Adobe Reader again. We run a network of Windows PCs, and the 'Mac room' mostly takes care of itself, so we don't have any experienced Mac administrators onsite. The Cannon is capable of Appletalk, but the PS driver seemed easier to work with (and Appletalk is currently disable on the Cannon. I'm not against using the Appletalk compatible drivers, but I would rather use the PS driver if at all possible - I don't want to open up the proverbial can of worms. If someone has any clues or suggestions that would help troubleshoot this problem, I would be grateful. I've already done some googling, but due to the obscure nature of this problem, I haven't been very successful.

  • Running KVM/XEN/Hyper-V VMs from a RAM disk, is this possible? Practical?

    - by Ausmith1
    Currently I'm using ESX (v3 and v4) to test a scripted OS (Windows 2003) and application install DVD. The DVD ISO (8GB) is mounted on a 1Gbps NFS datastore and the VMDK's (20GB) are on an SSD mounted via NFS over a 10Gbps link. It still takes a lot longer than I'd really like for to run through a test iteration and I'm wondering if mounting the virtual disks and ISO on a RAM disk on the same server as the hypervisor is running on would be worth my while. I can dedicate a server to this VM and 32GB of RAM in the system should be adequate to do the trick I'd guess. (1GB hypervisor OS, 28GB RAM disk and 2GB for the VM is < the 32GB available to me) Since hosting a RAM disk within ESX does not seem possible I'm open to trying KVM/Xen/Hyper-V. KVM would probably be my first choice of these three. Anyone out there tried this? Bear in mind this is purely for a test run of the installer, the VM will be discarded as soon as the test is completed so I'm not worried about losing data from the remote possibility of a power failure.

  • How to use AND/OR Building Block content in a Word 2007 template

    - by JimmyJames
    I am creating a Schedule of Work template and am successfully using Developer Tab and Quick Parts to allow user to choose content on an "either/or" basis: either A; OR B; OR C; etc., essentially choose one option from many. One Building Block control, one paragraph, nice and clean. Now what I need to do but cannot seem to figure out, is how to allow user to choose content on an "and/or" basis: either A AND B; A OR B AND C; B AND D AND E OR F; etc., essentially choose several options from many on a variable basis. One Building Block control, maybe one paragraph, maybe three or more paragraphs. Not so clean. I thought of building choice options for all possible paragraph combinations, but I can have as many as 7 or 8 different paragraphs, and that solution quickly becomes unworkable. Multiple controls--some of which will be left unused doesn't work either, since I cannot find an easy way to have a "Choose or Delete" control that actually deletes if "Delete" is chosen. Recommendations are most welcome.

  • How can I copy this quote from PDF?

    - by isme
    I'm reading a PDF copy of Jerome H. Friedman's paper "Data Mining and Statistics: What's the Connection?" using Google Chrome and the Adobe Reader plugin. It contains an amusing quote that I want to copy and paste to my blog. I used the mouse to select the text of the quote and pressed CTRL + C to copy the text. The document looks like this: When I paste the text into Notepad, Stack Overflow, or anywhere else, the product is Wingdings-like gibberish: ????????????????????????|?????????|????? ?????|??????????????????????????????????????????????????|?????????????? ??????????????P????? ?????????????????????P?|?????????|?????????????????????????????????????????????????????? ????????????Þ?????????????????????????????????|???|??????????????????????????? The text should instead look like this: A difference between statisticians and computer scientists in this field seems to be that when a statistician has an idea he or she writes a paper; a computer scientist starts a company. I had to type that text out manually. This is feasible for such a small quote, but how do I actually copy what I see? Is it something unusual about the PDF, the browser, the plugin, or some combiniation of the three?

  • Software/hardware to build video streaming server?

    - by Sasha Yanovets
    I am looking for a video streaming server solution, something like online TV server, with ability to make live broadcasts in the internet. What software could you recommend for that? What kind of hardware it should run on, should be there anything special? I am looking for a solution that could be scaled up to at least 1000 simultaneous users online with good resolution of video. I think it is good to have general answer on what direction to choose. But here more details on my specific case: I just looking for a solution almost from scratch. We have some video content that we've produced, but it is not delivered over internet yet. We do not tied to any particular vendor for now. We want to make 24 hours of steaming three 8 hour blocks with change of content every day. We want the ability to make regular live broadcasts. I guess we will need to have several options of streaming quality (low ~56 kb/s mid ~273 kb/s). Some terms just foreign to me (like play-truncation rate), if you could point out what parameters we should avare of, it would be great. Uplink to the internet is to be determined. We plan to start from something and scale up on the way. If you are already have some kind of media streaming server, just describe its configuration here (hardware, OS, software), peak number of concurrent users it serves. I think it could help people approaching this task.

  • How to replicate a windows servers (IIS,Files,ConfigurationState)?

    - by Geo
    Maybe a better question is: What is the closest competitor for DoubleTake? I am looking to replicate a windows production server in case it fails have a immediate backup. Any idead? NOTE 1: I forget to add that this server is on the EC2 Amazon Cloud. NOTE 2: The main situation we have is recreating the configuration settings like IIS, FTP Server, SQL Server, SVN Server. NOTE 3: So far I have been giving three options as answers for my original question: AppAssurance -- After talking to their sales team they do not support Amazon as cloud provider. Basically there is a technical need to be able to reboot from a disk or similar media. So ESX Virtual machine environment will work, but not the EC2. Acronis -- which works as a backup in ghost style. This will work for other type of scenarios. Use the Amazon EC2 API -- This option is ideal, but only works if you are developing a cloud application rather than hosting a regular application in a cloud scenario. This means that I am still looking for the answer. Any other ideas.

  • Forcing users to change password on first login - Windows Server 2008 R2 Remote Desktop Services

    - by George Durzi
    I'm setting up a demo lab environment in which each demo lab user is assigned 4 accounts to use in the lab. Users access the lab via Remote Desktop to the "client" machine in the lab - exposed at demolab.mydomain.com. The Client machine is a Windows 2008 Server R2 Enterprise Edition server The Remote Desktop Services role is configured on this server Remote Connection settings are configured to allow users to connect with any version of the Remote Desktop Client All accounts are members of the local Administrators and Remote Desktop Users groups All accounts are configured to be forced to change the default password after first login The user is instructed to remote into the lab with an account designated as their main account, and establish 3 more remote desktop sessions within the lab using their 3 other assigned demo lab accounts. When establishing the initial remote desktop connection to the lab using their main account, the user sees the change password dialog as expected. However, after logging in and trying to establish remote desktop connections to the server with their three other accounts, they are prompted that they need to change the password after logging in but can't continue with the login process - they don't see the expected change password experience. After logging in with a primary accounts, it doesn't make a difference if I try establishing a Remote Desktop connection to the environment using the name of the server, e.g. Client, or demolab.mydomain.com. I experimented with changing the settings for Remote Connections to require NLA but that didn't make a different. Appreciate any tips. Thanks

  • Ping and crawling not working, site still resolving

    - by Andrew Alexander
    Ok, so we're trying to figure out why the site of one of our clients isn't being crawled by Google (we've ruled out robots.txt or meta tags) When we go to the site, either IP address or domain name, the site resolves, everything works. However, Google is getting a 302 redirect (which it apparently isn't following for crawling), and when we ping the address, it times out (note, the site is still resolving in the browser throughout all of this). The site is built in ASP.Net (I assume C#) and so my thoughts were that it was an errant redirect rule, or some other sort of server side issue. We also thought that it might be due to incorrect domain pointing (but if we try to ping the IP, it doesn't work, so that sorta rules that out). We're really not sure what is causing all of these errors, or even if they have one single source. Anyone have any ideas what could be going on? Do you need any more information? To boil it down in a TL; dr: * Site resolving in browser, both IP and domain name. No problems here. * Site not being crawled by Google (gets a 302 it doesn't seem to follow) - it is not due to robots.txt or meta tags * Ping is not working for the IP address. This is very odd, because again, the IP address seems to work fine in the browser. * Our thoughts are either redirect rule issue, domain pointing issue, or possibly some errant code - or some combination of the three

  • wget crawling search results of news website

    - by kiltek
    I am trying to crawl the search results of a news website using wget. The name of the website is www.voanews.com. After typing in my search keyword and clicking search, it proceeds to the results. Then i can specify a "to" and a "from"-date and hit search again. After this the URL becomes: http://www.voanews.com/search/?st=article&k=mykeyword&df=10%2F01%2F2013&dt=09%2F20%2F2013&ob=dt#article and the actual content of the results is what i want to download. To achieve this I created the following wget-command: wget --reject=js,txt,gif,jpeg,jpg \ --accept=html \ --user-agent=My-Browser \ --recursive --level=2 \ www.voanews.com/search/?st=article&k=germany&df=08%2F21%2F2013&dt=09%2F20%2F2013&ob=dt#article Unfortunately, the crawler doesn't download the search results. It only gets into the upper link bar, which contains the "Home,USA,Africa,Asia,..." links and saves the articles they link to. It seems like he crawler doesn't check the search result links at all. What am I doing wrong and how can I modify the wget command to download the results search list links (and of course the sites they link to) only ?

  • How do I `SUM` by multiple columns in Excel

    - by dwwilson66
    I have a comma delimited file that includes two columns date/time (which imports as Excel's mm/dd/yyyy hh:mm custom format) and status of 1 or 0. The status represents a piece of equipment either being on or off. I'm trying to generate a graph that will show, hours up vs. down by day. CONSIDER: 1/1/2012 00:00, 1 1/1/2012 03:00, 0 1/1/2012 14:00, 1 1/3/2012 00:00, 0 This tells me that the equipment was up for three hours, down for eleven hours, and then up for thirty-four hours (across two calendar days). However, I would like to generate a graph that shows how many hours PER DAY we were up or down. CONSIDER: 1/1 XXXXXXXXXXXXX----------- (up 13, down 11) 1/2 XXXXXXXXXXXXXXXXXXXXXXXX (up 24) To me, it seems that I need to generate a dataset summing HOURS by STATUS by CALENDAR DAY...but I can't seem to find a flavor of pivot table or nested SUM(IF(SUMIF(...))) combination to make it work. Most troubling is accounting for date changes...in my example above, since my uptime starting at 14:00 on 1/1/2012 crosses midnight, I need to know that 10 uptime hours get totalled with 1/1/2012 and 24 uptime hours get totalled with 1/2/2012. I may be able to do something with a calendar list to drive the date summation, but then I need a way to compare 01/01/2012 to 01/01/2012 03:00 as equal. There's got to be a way along the lines of if(INTEGER-PORTIONS-OF-SERIAL-DATES-ARE-EQUAL,TOTAL-HOURS-IF-VALUE-IS_1,0) but nothing's worked so far. Any suggestions? I've been battling this most of the day, and need a fresh perspective. Thanks

  • How ZFS handles online replacement in a RAID-Z (theoretical)

    - by Kevin
    This is a somewhat theoretical question about ZFS and RAID-Z. I'll use a three disk single-parity array as an example for clarity, but the problem can be extended to any number of disks and any parity. Suppose we have disks A, B, and C in the pool, and that it is clean. Suppose now that we physically add disk D with the intention of replacing disk C, and that disk C is still functioning correctly and is only being replaced out of preventive maintenance. Some admins might just yank C and install D, which is a little more organized as devices need not change IDs - however this does leave the array degraded temporarily and so for this example suppose we install D without offlining or removing C. Solaris docs indicate that we can replace a disk without first offlining it, using a command such as: zpool replace pool C D This should cause a resilvering onto D. Let us say that resilvering proceeds "downwards" along a "cursor." (I don't know the actual terminology used in the internal implementation.) Suppose now that midways through the resilvering, disk A fails. In theory, this should be recoverable, as above the cursor B and D contain sufficient parity and below the cursor B and C contain sufficient parity. However, whether or not this is actually recoverable depnds upon internal design decisions in ZFS which I am not aware of (and which the manual doesn't say in certain terms). If ZFS continues to send writes to C below the cursor, then we are fine. If, however, ZFS internally treats C as though it were gone, resilvering D only from parity between A and B and only writing A and B below the cursor, then we're toast. Some experimenting could answer this question but I was hoping maybe someone on here already knows which way ZFS handles this situation. Thank you in advance for any insight!
