  • What does "single-bit ECC errors were detected on the RAID controller" mean?

    - by jsp
    I have a Dell T7600 with a Perc H710P RAID controller and 4 attached 3TB drives. Over the past few months the RAID controller has been intermittently reporting errors on boot: "no boot device found", "adapter at baseport is not responding", disks frequently reported as missing or failed. I have since replaced the RAID controller, the 4 hard drives, and finally the system's motherboard. After replacing the motherboard and rebooting a few times, I got the error Single bit ECC errors were detected on the RAID controller. Please contact technical support to resolve this issue. After rebooting about 20 more times, I haven't seen the ECC error. The system seems otherwise OK, except for the fact that the disk fans will sometimes start blowing at full blast when the the system is sitting completely idle and not stop until I reboot. Are the ECC errors in memory on the RAID controller? Or, does the RAID controller map in system memory, and the ECC errors are really in system memory? Or, are the ECC errors in the 1GB cache that resides in the RAID controller?

  • Need help with yum,python and php in CentOS. (I made a complete mess!)

    - by pek
    Hello, a while back I wanted to install some plugins for Trac but it required python 2.5 I tried installing it (I don't remember how) and the only thing I managed was to have two versions of python (2.4 and 2.5). Trac still uses the old version but the console uses 2.5 (python -V = Python 2.5.2). Anyway, the problem is not python, the problem is yum (which uses python). I am trying to upgrade my PHP version from 5.1.x to 5.2.x. I tried following this tutorial but when I reach the step with yum I get this error: [root@XXX]# yum update Loading "installonlyn" plugin Setting up Update Process Setting up repositories Reading repository metadata in from local files Traceback (most recent call last): File "/usr/bin/yum", line 29, in ? yummain.main(sys.argv[1:]) File "/usr/share/yum-cli/yummain.py", line 94, in main result, resultmsgs = base.doCommands() File "/usr/share/yum-cli/cli.py", line 381, in doCommands return self.yum_cli_commands[self.basecmd].doCommand(self, self.basecmd, self.extcmds) File "/usr/share/yum-cli/yumcommands.py", line 150, in doCommand return base.updatePkgs(extcmds) File "/usr/share/yum-cli/cli.py", line 672, in updatePkgs self.doRepoSetup() File "/usr/share/yum-cli/cli.py", line 109, in doRepoSetup self.doSackSetup(thisrepo=thisrepo) File "/usr/lib/python2.4/site-packages/yum/init.py", line 338, in doSackSetup self.repos.populateSack(which=repos) File "/usr/lib/python2.4/site-packages/yum/repos.py", line 200, in populateSack sack.populate(repo, with, callback, cacheonly) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 91, in populate dobj = repo.cacheHandler.getPrimary(xml, csum) File "/usr/lib/python2.4/site-packages/yum/sqlitecache.py", line 100, in getPrimary return self._getbase(location, checksum, 'primary') File "/usr/lib/python2.4/site-packages/yum/sqlitecache.py", line 86, in _getbase (db, dbchecksum) = self.getDatabase(location, metadatatype) File "/usr/lib/python2.4/site-packages/yum/sqlitecache.py", line 82, in getDatabase db = self.makeSqliteCacheFile(filename,cachetype) File "/usr/lib/python2.4/site-packages/yum/sqlitecache.py", line 245, in makeSqliteCacheFile self.createTablesPrimary(db) File "/usr/lib/python2.4/site-packages/yum/sqlitecache.py", line 165, in createTablesPrimary cur.execute(q) File "/usr/lib/python2.4/site-packages/sqlite/main.py", line 244, in execute self.rs = self.con.db.execute(SQL) _sqlite.DatabaseError: near "release": syntax error Any help?

  • How do I easily repair a single unreadable block on a Linux disk?

    - by Nelson
    My Linux system has started throwing SMART errors in the syslog. I tracked it down and believe the problem is a single block on the disk. How do I go about easily getting the disk to reallocate that one block? I'd like to know what file got destroyed in the process. (I'm aware that if one block fails on a disk others are likely to follow; I have a good ongoing backup and just want to try to keep this disk working.) Searching the web leads to the Bad block HOWTO, which describes a manual process on an unmounted disk. It seems complicated and error-prone. Is there a tool to automate this process in Linux? My only other option is the manufacturer's diagnostic tool, but I presume that'll clobber the bad block without any reporting on what got destroyed. Worst case, it might be filesystem metadata. The disk in question is the primary system partition. Using ext3fs and LVM. Here's the error log from syslog and the relevant bit from smartctl. smartd[5226]: Device: /dev/hda, 1 Currently unreadable (pending) sectors Error 1 occurred at disk power-on lifetime: 17449 hours (727 days + 1 hours) ... Error: UNC at LBA = 0x00d39eee = 13868782 There's a full smartctl dump on pastebin.

  • Can I have a single solid state drive and a RAID array on the same machine?

    - by jaminto
    Hi- To summarize, i'm looking to use a single solid state drive as my primary drive, and two conventional sata drives in a RAID 1 configuration for data. I am trying to install 64-bit Windows 7 onto this configuration. Is this possible? Here are the details: I built a desktop that has been running 64-bit Vista on two 500Gb in a RAID 1 array for a few years. I just purchased an Intel X25-M 80Gb Sata Solid-State Drive, and was planning on using this a my primary drive, and keeping the RAID 1 array as my data drive. I added the SSD drive and in the RAID setup, configured it as a RAID 0 array of only one disk. Then, I tried to do a clean install of windows 7 64-bit, but got stuck in the "Missing driver for CD/DVD drive" black hole of selecting driver files and Windows telling me that i don't have the appropriate driver for my hardware. The missing hardware is NOT a CD/DVD drive, since i'm installing off of my only CD/DVD drive. Plus at one point i was able to point it at a driver for my raid controller, and then my hard drives magically showed up as browsable sources for finding drivers for some other unnamed device that setup couldn't recognize. After a few hours of trying drivers (this was a very slow process) i decided to reboot and look at the BIOS settings. I'm using an ASUS M2A-VM motherboard which has an ATI SB600 RAID controller on board. I switched the "On board SATA Type" setting from "SATA" to "AHCI" thinking that since AHCI is an Intel thing, this would help. Unfortunately, this abandoned my RAID configuration, and my previously mirrored drives are showing up as separate drives when i boot into my current windows installation. Am i trying to do the impossible here? Should i just buy a separate SATA/RAID PCI card and plug the SSD into that? Any help would be greatly appreciated.

  • How to print multiple Excel sheets into a single PDF file?

    - by Anriëtte Combrink
    I am trying to print multiple sheets from the same Excel workbook into ONE PDF file. But it frequently prints them seperately or only the first sheet. I selected all the sheets and made them have the same page setup. I am working on Tiger and from the Print dialogue, I click on the left-hand bottom button, "Save PDF" and from there I choose "Save PDF-X". Anyone have another solution for me?

  • Can I open a Disk2vhd created VHD file with 7-zip?

    - by tjrobinson
    I've created a VHD file of my C: drive, for backup purposes, using Disk2vhd 1.0. When I try opening the file using 7-Zip 4.65 (to view the contents) I get the error: "Can not open the file XXX as an archive". Does anyone know why this is? I have to assume that either the VHD creation failed and it's a corrupted file, or Disk2vhd creates a variation of the VHD format that 7-Zip doesn't support.

  • MsMpEng.exe (Windows Defender?) uses a lot of CPU at startup and runs two instances on a single core

    - by dlamblin
    I'm using Windows XP Professional SP2 on a single core AMD64 processor, and I've got two instances of MsMpEng.exe starting up when I start up and log in. They use 64MB and 32MB of ram and 140MB and 80MB of virtual memory, and fluctuate around 80% CPU usage for about 5 minutes at start up. They are (I read) associated with Windows Defender, but I'm concerned about: There's two of them, everything I read generally has only one reported. They might be scanning each other, and I want that to stop. They might be getting scanned by avgrsx.exe (AVG Free 8) (uses about 16Mb v ram) They might also be scanning moe.exe (assosciated with ms live mesh, which I'm considering getting rid of) Lastly I have Microsoft Security Essentials. I don't know the process name associated there. The main concern of mine (apart from the double instances) is that these are all trying to prioritize scanning each other at once except maybe moe.exe. This might seem legitimate but is likely a useless drain on resources. Have I made a mistake in having all of these installed, or is there a way to inform them not to do whatever they're doing that's taking about 5+ minutes at start up? [I also have Google Desktop, but I'm keeping that.] Comment if none of this makes sense to you.

  • How can I open a file whose name starts with "-"?

    - by PJ
    I am running Ubuntu, and would like to open a file whose file name starts with "-"(minus). When I try to open the file with pico or vim, the command thinks that the "-" sign is an option for the command. I tried enclosing the file name with quotes ('), but I still get the same error. I tried with bash and zsh, but still the same error.

  • KeePass: use a key file or a regular password?

    - by RCIX
    I'm setting up a KeePass database and it offers the ability to use a key file, which it says is more secure because it can use a longer and more complex password but is easier to break because you only need the key file to open the database. I'll only be using the key file on 2 computers (one desktop and one laptop), wo which is the best option? Note that it's definitely more appealing to use the key file for me because i have a hard time remembering anything close to a random password.

  • Can I use a single SSLCertificateFile for all my VirtualHosts instead of creating one of it for each VirtualHost?

    - by user65567
    I have many Apache VirtualHosts for each of which I use a dedicated SSLCertificateFile. This is an configuration example of a VirtualHost: <VirtualHost *:443> ServerName subdomain.domain.localhost DocumentRoot "/Users/<my_user_name>/Sites/users/public" RackEnv development <Directory "/Users/<my_user_name>/Sites/users/publ`enter code here`ic"> Order allow,deny Allow from all </Directory> # SSL Configuration SSLEngine on #Self Signed certificates SSLCertificateFile /private/etc/apache2/ssl/server.crt SSLCertificateKeyFile /private/etc/apache2/ssl/server.key SSLCertificateChainFile /private/etc/apache2/ssl/ca.crt </VirtualHost> Since I am maintaining more Ruby on Rails applications using Passenger Preference Pane, this is a part of the apache2 httpd.conf file: <IfModule passenger_module> NameVirtualHost *:80 <VirtualHost *:80> ServerName _default_ </VirtualHost> Include /private/etc/apache2/passenger_pane_vhosts/*.conf </IfModule> Can I use a single SSLCertificateFile for all my VirtualHosts (I have heard of wildcards) instead of creating one of it for each VirtualHost? If so, how can I change the files listed above?

  • Can I use IIS to do ActiveDirectory single-sign-on for another website?

    - by brofield
    I'm trying to add Active Directory single-sign-on support to an existing SOAP server. The server can be configured to accept a trusted reverse-proxy and use the X-Remote-User HTTP header for the authenticated user. I want to configure IIS to be the trusted proxy for this service, so that it handles all of the Active Directory authentication for the SOAP server. Basically IIS would have to accept HTTP connections on port X and URL Y, do all the authentication, and then proxy the connection to a different server (most likely the same X and Y). Unfortunately, I have no knowledge of IIS or AD (so I am trying my best to learn enough to build this solution) so please be gentle. I would assume that this is not an uncommon scenario, so is there some easy way to do this? Is this sort of functionality built into IIS or do I need to build some sort of IIS proxy program myself? Is there a better option for getting the authentication done and the X-Remote-User HTTP header set than requiring IIS? Update: For example, what I am trying to create is: [CLIENT] [IIS] [AD] [SOAP-SERVER] 1. |---------------->| 2. |<--------------->|<---------->| 3. |--------------------------->| 4. |<---------------------------| 5. |<----------------| 1. POST to http://example.com/foo/bar.cgi 2. Client is not authenticated, so do authentication 3. Once validated, send request to server (X-Remote-User: {userid}) 4. Process request, send response 5. Forward response to client I need to know how to configure IIS to do the automatic authentication of the user using AD, and then to proxy the request to the actual server, sending the userid in the X-Remote-User HTTP header.

  • Simple Linux program that takes any HTTP/HTTPS request and returns a single page?

    - by ultrasawblade
    I have a Linux box operating as router. There's a NIC that's connected to the internet (WAN), a NIC connected to an 8-port GbE switch (LAN), and a NIC connected to a Linksys wireless N-router (WLAN). Routing between everything is working perfectly. I have security completely disabled on the wireless router, but the WLAN NIC is firewalled such that it will only accept DNS queries and PPTP VPN connections. Currently HTTP/HTTPS traffic and everything else is blocked. I would like to run something that listens on port 80/443 of the WLAN NIC, and, for non VPN'ed connections, given any HTTP/HTTPS request it will return a single webpage saying "Unauthenticated" and explain how to sign into the VPN. A transparent proxy seems to be what I need, but my searches all seem to direct me to Squid, which is already running on my server and seems overkill for this simple task. Is there a simpler, lightweight program out there that does just this or should I just suck it up and run two instances of Squid (or figure out how to configure it)? Or, is this entire VPN thing I'm doing complete nonsense and I should just enable encryption on the wireless router?

  • Why does writing a file to an NFS share send a COMMIT operation to the NFS server?

    - by Antonis Christofides
    I have a Debian squeeze (2.6.32-5-amd64) which is at the same time a NFS4 server and client (it mounts itself through NFS4). The local directory that leads directly to disk is /nfs4exports/mydir, whereas /nfs4mounts/mydir is the same thing mounted through NFS, using the machine's external IP address. Here is the line from fstab: 192.168.1.75:/mydir /nfs4mounts/mydir nfs4 soft 0 0 I have an application that writes many small files. If I write directly to /nfs4exports/mydir, it writes thousands of files per second; but if I write to /nfs4mounts/mydir, it writes 4 files per second or so. I can greatly increase speed if I add async to /etc/exports. (Writing a single large file to the NFS-mounted directory goes at more than 100 MB/s.) I examine the server statistics and I see that whenever a file is written, it is "committed" (this also happens with NFSv3): root@debianvboxtest:~# mount -t nfs4 192.168.1.75:/mydir /mnt root@debianvboxtest:~# nfsstat|grep -A 2 'nfs v4 operations' Server nfs v4 operations: op0-unused op1-unused op2-future access close commit 0 0% 0 0% 0 0% 10 4% 1 0% 1 0% root@debianvboxtest:~# echo 'hello' >/mnt/test1056 root@debianvboxtest:~# nfsstat|grep -A 2 'nfs v4 operations' Server nfs v4 operations: op0-unused op1-unused op2-future access close commit 0 0% 0 0% 0 0% 11 4% 2 0% 2 0% Now in the RFC, I read this: The COMMIT operation is similar in operation and semantics to the POSIX fsync(2) system call that synchronizes a file's state with the disk (file data and metadata is flushed to disk or stable storage). COMMIT performs the same operation for a client, flushing any unsynchronized data and metadata on the server to the server's disk or stable storage for the specified file. I don't understand why the client commits. I don't think that the "echo" shell built-in command runs fsync; if echo wrote to a local file and then the machine went down, the file might be lost. In contrast, the NFS client appears to be sending a COMMIT upon completion of the echo. Why? I am reluctant to use the async NFS server option, because it would apparently ignore COMMIT. I feel as if I had a local filesystem and I had to choose between syncing every file upon close and ignoring fsync altogether. What have I understood wrong?

  • Move the uploads folder in Wordpress

    - by Victor Hurdugaci
    Currently, my Wordpress' upload folder is located in \wp-content\uploads. Initially there was no structure so all files were put there. After a while it was changed to upload the files in \wp-content\uploads\YEAR\MONTH. Now that folder contains a mix of files (those starting with + are folders) like: +wp-content | +2010 | | +02 | | | File-1 | | | File-2 | | | .. | | | File-n | | +01 | | | File-1 | | | File-2 | | | .. | | | File-n | +2009 | | +12 | | | File-1 | | | File-2 | | | .. | | | File-n | | +11 | | | File-1 | | | File-2 | | | .. | | | File-n | +.. | | | .. | Unstructured-file-1 | Unstructured-file-2 | ... | Unstructured-file-n Based on the dates of the unstructured files, I would like to move them in a structured hierarchy (based on date, move it to a folder \wp-content\uploads\YEAR\MONTH). Now, my questions are: Where do I write and execute a script to the movement (I don't have full access to the server, just to a cPanel and to the Wordpress Admin page)? What must be updated so that the links in posts, that reference the unstructured files, point to the new location of those files? Not fully related to the previous description: is it alright to move the whole uploads folder to another location, like \uploads? PS: Moving the files/updating the database manually is not an option :)

  • Getting SEC to only monitor latest version of a log file?

    - by user439407
    I have been tasked with running SEC to help correlate PHP logs. The basic setup is pretty straightforward, the problem I'm having is that we want to monitor a log file whose name contains the date(php-2012-10-01.log for instance). How can I tell SEC to only monitor the latest version of the file(and of course switch to the newest log file every day at midnight) I could do something like create a latest version of the file that links to the latest version and run a cron job at midnight to update the link, but I am looking for a more elegant solution

  • Windows 7 mouse multi selection on windows explorer with CTRL and point to select / single click to open

    - by bortao
    This is something that have annoyed me since i changed to Windows 7. I don't do double click for a long time now since windows introduced 1 click selection (Folder Options Click items as follows Single click to open an item). The problem is, when i click Control and hover over the items, they select/deselect automatically every small amount of mouse movement i make. What i want is to select/deselect the items only when i enter/exit them. So to deselect an item im hovering, i have to move the mouse out of it, and then back in. I'm using Intellimouse Explorer official drivers. (edit) Here's another related annoyance: When you are hovering something and move the mouse inside other item (Holding Ctrl) The new item may or may not be selected. If you continue moving the mouse it gets selected/deselected as you move. (more edit) I have found that the parameter HKCU\Control Panel\Mouse\MouseHoverHeight / MouseHoverWidth have some influence here. If it's set to 2, the item select/deselect really quickly as you move the mouse. When set to larger numbers, its slower. But setting to 20 or 200 don't seem to be much different.

  • Linux: how to restore config file using apt-get/aptitude?

    - by o_O Tync
    I've occasionally lost my config file "/etc/mysql/my.cnf", and want to restore it. The file belongs to package mysql-common which is needed for some vital functionality so I can't just purge && install it: the dependencies would be also uninstalled (or if I can ignore them temporarily, they won't be working). Is there a way to restore the config file from a package without un-ar-ing the package file? dpkg-reconfigure mysql-common did not restore it.
