• Intel ICH9/10R raid 5 drive failure

  - by davpen

  About a year ago I was using the native Intel ICH9R Raid 5 an Intel P35 based motherboard. The system was running Vista x64 and when one of the drives failed Vista blue screened on boot until I had figured out which drive had failed and removed it (a rather nerve racking hit and miss affair). The same thing happened some months later on another similar system so it wasn't a once off. This wasn't the robust raid 5 drive failure behavior that I would have hoped for and expected. I moved to Highpoint Rocketraid 2300 and haven't had any problems although I have yet to have a drive fail with this set up. But I am now looking to build a new system based on an i7 and Windows 7. At the moment Highpoint doesn't have drivers for Windows 7 so I am considering moving back to the on board Intel Raid. Yes I know I that I might get away with using the Vista drivers but I don't really want to take that chance with critical data. The question then is has anyone else experienced a drive failure with Intel raid and how did the OS and drivers handle it? Is it safe to go back?

• Ram question in VMware Server 2

  - by ToreTrygg

  Hi, I understand from the VMware Server 2 documentation that VMware Server 2 is capable of running a 64-bit guest OS underneath a 32-bit host OS, as long as the hardware running the box is 64-bit capable. Here's my situation. We currently have an underutilized XEON X3220 Quad Core 64bit Server, running Server 2003, 32-bit and 2gb of RAM (the motherboard is capable of 8gb ram). The server is currently used mainly for file and print services. It is also running Active Directory, Novell eDirectory and Groupwise 6.5. We are planning a micration to Microsoft Exchange, so the Novell eDirectory and Groupwise services will eventually be purged from this box, leaving only Active Directory, File and Print services. Being that this server is underutilized we are hoping to save hardware costs and virtualize our new Exchange investment. My question is this. Will VMware allow access to the "invisible" extra memory that Windows 32-bit won't see. Meaning, if we increase the full amount of system ram to 8gb (yes, I know the 32-bit host OS will only see a maximum of 4gb), will I be able to assign maybe 5gb to the new Server 2008 64-bit OS running Exchange and leave 3gb for the Guest OS (or maybe even a 6, 2 split). The second part of that would be, would it be better to just convert the main OS currently running to an image, convert the machine itself to ESXi and run both OSes as images under ESXi. Downtime for this box is critical, so my preference is most definitly with the first option because it presents very minimal downtime. Doing the second would make downtime quite a few hours to image the machine and then convert the image to a VMware Image.

• hp proliant dl360 disk diagnostic issue

  - by user1039384

  We recently got two used drives (15000) and installed on our HP proliant dl360 G5 server. Created RAID1 and used HP SmartStart CD to perform diagnostics. Interestingly, the Diagnostic tab immidiately fails on Logical drive testing saying the Disk1 should be replaced, while the Test tab successfully runs all the complete tests on both disks and does not find any issue. At the meantime, when booting to esxi 5, vSphere periodically shows the Disk1 as Unknown and Logical drive in recovery process. This happens every 5-10 minutes. Here is the log from HP SmartScan diagnostic: 1 - Device, Test: Logical Drive 1, Storage Controller in Slot 0 1 - Description: The controller has reported a critical error in the drive error log. 1 - Recommended Repair: This drive should be replaced. 1 - Failed Count: 44 1 - Error code: F157 There is also another error log record (see below): 2 - Device, Test: test_components/libstorage.so ID 2 - Description: An unexpected exception occurred while performing an operation. Exception message: CISS_StatusHandler::evaluate: commandStatus = 4 (INVALID); hexdump of CISS_ErrorInfo: 00000000: __ __ 04 __ 20 __ __ __ __ __ __ __ __ __ __ __ .... ... ........ 00000010: __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ ........ ........ 00000020: __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ ........ ........ Device: Hard Drive 2, Storage Controller in Slot 0 Property name: Bad Target Count 2 - Recommended Repair: Reboot or restart Insight Diagnostics. Retry the test. If the problem persists, upgrade to the latest version of Insight Diagnostics. 2 - Failed Count: 48 2 - Error Code: F62 Note that rebooting didn't help and I was running the latest diagnostic software version. Anyone has a clue? Is this a real disk issue? BTW, the controller is Smart Array E200i Thanks in advance

• Windows 7 restarts while being idle

  - by Ondrej Slinták

  My Windows 7 almost always restarts when I keep it idle for ~20-30mins. It happened randomly before, but lately, if I leave the computer I can be sure it's gonna restart after those 30mins. It never happens when I play games or work tho, just when it's idle. It's a fresh install of Windows 7 64bit. I had also problems while installing it, it always crashed while finalizing the install and I had to reinstall again. Eventually it installed on 3rd or 4th try after I deleted all of my partitions and added them again. I thought it might have been a hardware problem, but temperatures seem to be okay and I have no idea how to track what might have been causing it. Any ideas? I'm running Windows 7 64bit on: Gigabyte EX58-UD4P Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz NVIDIA GeForce GTX 260 6GB of DDR3 1066Mhz RAM WDC WD1001FALS-00J7B0 1TB SATA II I have a very bad feeling it might be something with HDD and its compatibility with Windows 7 as I haven't had those problems for 1 year while I had Vista. Edit: I checked Event Viewer critical errors from this night. PC restarted first time at 11:12pm, then at 3:06am and since then every ~20min until I came back to it. Error message is: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Source: Kernel-Power

• How to publish internal data to the internet - as simple as possible

  - by mlarsen

  I Asked this at Staock Overflow, but I would like your oppinion too as it has as much to do with administration as it does with coding. We have a .net 2-tier application where a desktop program is talking to a database. We support MS SQL Server 2000, 2005, 2008 and Oracle 9, 10 and 11. The application is sold, not as shrink-wrap, but pretty close. It is quite important for us that the installation and configuration is as easy as possible as installation instructions are usually supplied in written form to the customers internal IT-department. Our application is usually not seen as mission critical for the IT-department, so we need to keep their work down to a minimum. Now we are starting to get wishes for a web application build on top of the same data. The web application will be hosted by us and delivered as a SaaS application. Now the challenge is how to move data back and forth between the web application and the customers internal database. as I see it we have some requirements: We must be ready to handle the situation where the customers database is not accessible from the DMZ. I guess the easiest solution is that all communication is initiated from inside the customers lan. As little firewall configuration as possible. The best is if we can run without any special configuration as long as outgoing traffic from the customers lan are not blocked. If we need something changed in the firewall, we must be able to document that the change is secure. It doesn't have to be real time. Moving data in batches every ten minutes or so is OK. Data moves both ways, but not the same tables, so we don't have to support merges. It would be nice if we don't have to roll our own framework completely. Looking forward to hear your suggestions.

• Distributing processing for an application that wasn't designed with that in mind

  - by Tim

  We've got the application at work that just sits and does a whole bunch of iterative processing on some data files to perform some simulations. This is done by an "old" Win32 application that isn't multi-processor aware, so new(ish) computers and workstations are mostly sitting idle running this application. However, since it's installed by a typical Windows Install Shield installer, I can't seem to install and run multiple copies of the application. The work can be split up manually before processing, enabling the work to be distributed across multiple machines, but we still can't take advantage of multiple core CPUs. The results can be joined back together after processing to make a complete simulation. Is there a product out there that would let me "compartmentalize" an installation (or 4) so I can take advantage of a multi-core CPU? I had thought of using MS Softgrid, but I believe that still depends on a remote server to do the heavy lifting (though please correct me if I'm wrong). Furthermore, is there a way I can distribute the workload off the one machine? So an input could be split into 50 chunks, handed out to 50 machines, and worked on? All without really changing the initial application? In a perfect world, I'd get the application to take advantage of a DesktopGrid (BOINC), but like most "mission critical corporate applications", the need is there, but the money is not. Thank you in advance (and sorry if this isn't appropriate for serverfault).

• Can I convert an existing Firefox installation to ESR without a re-install?

  - by Iszi

  It took some jumping through hoops (including a mailing list subscription that I apparently didn't need) but I finally found where to download the Firefox ESR. This is great for fresh installs, but I was wondering if there's a way to simply convert existing installations to the ESR configuration without having to do a full install. As I understand it, the only difference between ESR and regular Firefox will be how they receive updates. After the new standard version of Firefox comes out, ESR releases will only receive critical security updates and bug fixes for the remainder of their support life. Newer versions of Firefox's standard build will have all the latest and greatest features, while ESR releases are meant to provide stability for environments that can't be expected to keep up with a new full version number change as often as Mozilla does them. In regular Firefox, the About screen shows that I am using the "release" update channel. Is switching to ESR really just a matter of switching the update channel? I presume this can be done in about:config by changing app.update.channel and probably also app.update.url. However, I don't know what these values should be for ESR or if anything else should be tweaked. So, is it possible to switch to ESR without a reinstall and, if so, how? (Note: While this question was written originally for Firefox 10, I expect any answers will apply to future ESR versions as well.)

• Backing up large network (~200 clients) -- Enough Bandwidth?

  - by mtkoan

  My company wants to institute a backup plan for all of the clients on our network, which is about 200. We back up our servers and SQL databases regularly, but its been our policy to not backup individuals. What is most critical for people is their Documents and PST files in Outlook. PST files can be very large, and most people's are ~1-1.5 GB around here. So with PST files alone that is 200-300 GB of data needing to be transferred daily to a sever for backup. Or compressing first, then transferring, but many of the machines are VERY old and such a task would grind their computer to a halt. Isn't this the reason networks use things like VMware -- to reduce network traffic and streamline backups? Or is this only to reduce hardware costs? Would this much network traffic everyday drastically slow down our network? Enough to the point we'd have to mandate it to be done at night only? Or could we stagger then through out the day? Really appreciate any input, thank you.

• SSH attack CentOS Amazon EC2

  - by user37143

  Hi, I run a few Rightscale CentOS AMI based instances on Amazon EC2. Two months back I found that our SSHD security is compromised( I had added host.allow and host.deny for ssh). So I created new instances and done an IP based ssh that allows only our IPs through AWS Firewall(ec2-authorize) and chnaged the ssh 22 default port to some other port but two days back I found I was not able to login to the server and when I tried on 22 port the ssh got connected and I found that sshd_conf was changed and when I tried to edit sshd_config I found root had no write permission on the file. So I tried a chmod and it said access denied for 'root' user. This is very strange. I checked secure log and history and found nothing informative. I have PHP, Ruby On Rails, Java, Wordpress apps running on these server. This time I did a chkrootkit scan and found nothing. I renamed the /etc/ssh folder and reinstalled openssh through yum. I had faced this on 3 instances on CentOS(5.2, 5.4) I have instances on Debian as well those working fine. Is this a CentOS/Rightscale issue. Guys, what security measures I should take to prevent this. Please support me this is very critical. Thanks

• Is execution of sync(8) still required before shutting down linux?

  - by Amos Shapira

  I still see people recommend use of "sync; sync; sync; sleep 30; halt" incantations when talking about shutting down or rebooting Linux. I've been running Linux since its inception and although this was the recommended procedure in the BSD 4.2/4.3 and SunOS 4 days, I can't recall that I had to do that for at least the last ten years, during which I probably went through shutdown/reboot of Linux maybe thousands of times. I suspect that this is an anachronism since the days that the kernel couldn't unmount and sync the root filesystem and other critical filesystems required even during single-user mode (e.g. /tmp), and therefore it was necessary to tell it explicitly to flush as much data as it can to disk. These days, without finding the relevant code in the kernel source yet (digging through http://lxr.linux.no and google), I suspect that the kernel is smart enough to cleanly unmount even the root filesystem and the filesystem is smart enough to effectively do a sync(2) before unmounting itself during a normal "shutdown"/"reboot"/"poweorff". The "sync; sync; sync" is only necessary in extreme cases where the filesystem won't unmount cleanly (e.g. physical disk failure) or the system is in a state that only forcing a direct reboot(8) will get it out of its freeze (e.g. the load is too high to let it schedule the shutdown command). I also never do the "sync" procedure before unmounting removable devices, and never hit a problem. Another example - Xen allows the DomU to be sent a "shutdown" command from the Dom0, this is considered a "clean shutdown" without anyone having to login and type the magical "sync; sync; sync" first. Am I right or was I lucky for a few thousands of system shutdowns?

• How should I perform database maintenance on a 24x7 system

  - by solublefish

  I'm a software developer who inherited a part-time DBA role. I'm responsible for an application backed by a small, high-volume 24x7 database on SQL Server 2008. While there's other stuff in the DB, the critical piece is a 50GB, 7.5M row table that serves 100K requests/sec during peak load, and about half that at "night". This is 99%+ read traffic, but the writes are constant, and required. I need to be able to perform periodic maintenance without a maintenance window. Say an index rebuild, a job to purge old data, Windows Update, or hardware upgrade. Most of the advice I've seen is along the lines of "MAKE a maintenance window." While I appreciate the sentiment, I hope there's another way. If it will solve this problem, I do have the ability to purchase new hardware or modify the database, the clients (a set of web services servers), and much of the application code (ADO.NET + ASP.NET). I've been thinking along the lines of using the warm spare (or a 3rd server) to do the maintenance, and then "swap" it into production. 1 Synchronize the spare by restoring backups, including a current transaction log. 2 Perform the maintenance tasks. 3 Reconfigure clients to connect to the spare server. Existing connections are finished within a minute or so. 4 The spare server is now the production server. The problem remaining is that the new production server is now out of date by however long it took to perform maintenance. Is there some way that the original production server can be made to queue up changes and merge them to the spare between steps 2 and 3? Any other ideas?

• Symantec Backup Exec 12 Tape Alert.

  - by Adam

  Every day, I run 5 backups using 6 tapes. Each day, when I run the inventory, I get a tape alert Error. This occurs every day, on the same job. The error is: Job 'Inventory Daily ********' has reported Multiple Tape Alerts on server '******' Please refer to job log *****.xml for more information. When i look at the Job log, the Utility Job Information says: The device has reported the following TapeAlert diagnostic information Information- The library has been manually turned offline and is unavailable for use. Robotic library for device: PV132T 500 Warning - Library security has been compromised. Robotic Library for device: PV132T 500. Critical - The library has detected a inconsistency in its inventory. 1.Redo the library inventory to correct the inconsistency. 2. Restart the operation. Check the applications users manual or hardware users manual for specific instructions on redoing the library inventory. Roboric Library for Device PV132T 500. When I run the same inventory for a second time, the job completes successfully. I am using Symantec Backup Exec 12 running on Windows Server 2008. I am using a Dell Powervault 132T 500 tape drive. If anyone can help me on how to resolve this problem, it would be very much appreciated.

• Did chkdsk make it harder to restore files?

  - by neyl

  My friend asked me to try and fix his loaded Sansa Clip + which wasn't playing. After opening it in MSC mode I discovered that the Music directory was empty and total of all files was only a few MB. However Disk properties showed me that it was 7Gb full. I then ran Tools - Error Checking and Windows dutifully informed me that disk was corrupt and I should run again Allowing Windows to Fix Errors. I did that and it told me everything was fixed and that all files were placed in FOUND.000 Dir. FOUND.000 was about 7.5 GB with FILE0000-1546 . CHK. (I am aware of methods like ChkBack to scan and convert to mp3 etc BUT Original filenames and structure needed!) Now I started getting worried that I made things worse! I have plenty of experience with Data Recovery Programs - Recuva, Restore My Files etc. and I was anyhow planning to use them to scan the drive. But NOW after CHKDSK "fixed" the drive maybe it modified critical FAT information vital for data recovery. So I run these programs and 0!!!. No trace of files! I tried a ton of Recovery Programs with same results TILL EaseUS Data Recovery Wizard found all files and I purchased program for $55! My Question In your opinion - did running CHKDSK with automatic fixing of errors make matters worse (i.e. many data recovery progs. didn't find a trace and they would have done if not for chkdsk) or was the filesystem too corrupt anyhow for regular File Recovery Progs.? If I would be a Professional - would I be responsible for running CHKDSK - automatic Fixing. Do you know of a better Data Recovery Program than EaseUs Data Recovery wizard - According to my experience I haven't found better!? Thanks

• Should tripwire be entering /proc?

  - by dsadinoff

  When initializing the db with tripwire --init it spat out a bunch of errors pertaining to /proc: ### Warning: File system error. ### Filename: /proc/16982/fd/4 ### No such file or directory ### Continuing... ### Warning: File system error. ### Filename: /proc/16982/fdinfo/4 ### No such file or directory ### Continuing... ### Warning: File system error. ### Filename: /proc/16982/task/16982/fd/4 ### No such file or directory ### Continuing... ### Warning: File system error. ### Filename: /proc/16982/task/16982/fdinfo/4 ### No such file or directory ### Continuing... ### Warning: Duplicate object encountered. ### /proc/sys/net/ipv6/neigh This feels like noise. The twpol.txt file has the following clause: # # Critical devices # ( rulename = "Devices & Kernel information", severity = $(SIG_HI), ) { /dev -> $(Device) ; /proc -> $(Device) ; } Which, if I understand it right, is going to cause tripwire to care deeply about the entire contents of /proc. Shouldn't it just care about the static parts of /proc like the drivers and such, and not the per-pid stuff? Why does it ship like this?

• How can I prevent Apache from asking for credentials on non SSL site

  - by Scott

  I have a web server with several virtual hosts. Some of those hosts have an associated ssl site. I have a DirectoryMatch directive in my main config file which requires basic authentication to any directory with secured as part of the directory path. On sites that have an SSL site, I have a rewrite rule (located in the non ssl config for that site), that redirects to the SSL site, same uri. The problem is the http (80) site asks for credentials first, and then the https (443) site asks for credentials again. I would like to prevent the http site from asking and thus avoid the potential for someone entering credentials and having them sent in clear text. I know I could move the DirectoryMatch down to the specific site, and just put the auth statement in the SSL config, but that would introduce the possibility of forgetting to protect critical directories when creating new sites. Here are the pertinent declarations: httpd.conf (all sites): <DirectoryMatch "_secured_"> AuthType Basic AuthName "+ + + Restrcted Area on Server + + +" AuthUserFile /home/websvr/.auth/std.auth Require valid-user </DirectoryMatch> site.conf (specific to individual site) <DirectoryMatch "_secured_"> RewriteEngine On RewriteRule .*(_secured_.*) https://site.com/$1 </DirectoryMatch> Is there a way to leave DirectoryMatch in the main config file and prevent the request for authorization from the http site? Running Apache 2 on Ubuntu 10.04 server from the default package. I have AllowOverride set to none - I prefer to handle things in the config files instead of .htaccess.

• compile ntp without ssl

  - by Zulakis

  I need to deploy ntp to a very space-critical pxe-imaging-system. (Yes, each KB matters.) Footprint needs to be as small as possible, so I want to compile ntp without linking openssl. According to the manual this is should be possible: If available, the OpenSSL library from http://www.openssl.org is used to support public key cryptography. The library must be built and installed prior to building NTP. The procedures for doing that are included in the OpenSSL documentation. The library is found during the normal NTP configure phase and the interface routines compiled automatically. Only the libcrypto.a library file and openssl header files are needed. If the library is not available or disabled, this step is not required. I already tried out ./configure --without-openssl however, this didn't help. This is my ldd output: ldd ntpd/ntpd linux-gate.so.1 => (0xb7706000) libm.so.6 => /lib/i686/cmov/libm.so.6 (0xb76d5000) libcrypto.so.0.9.8 => /usr/lib/i686/cmov/libcrypto.so.0.9.8 (0xb7582000) librt.so.1 => /lib/i686/cmov/librt.so.1 (0xb7578000) libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb741d000) /lib/ld-linux.so.2 (0xb7707000) libdl.so.2 => /lib/i686/cmov/libdl.so.2 (0xb7419000) libz.so.1 => /usr/lib/libz.so.1 (0xb7404000) libpthread.so.0 => /lib/i686/cmov/libpthread.so.0 (0xb73eb000) The system I am compiling on is 32-bit debian lenny using openssl 0.9.8g-15+lenny16. What is the correct configure option to compile ntp without openssl?

• How to fix IE starting when I try to start Opera?

  - by Scott Leis

  I have a problem that started today, where trying to run any of the 3 versions of Opera I have installed causes Internet Explorer to start instead. The Opera versions I have installed are 9.64, 10.10, and 10.63. My OS is Windows Vista with the latest critical/important updates. The behaviour is the same regardless of whether I double-click a shortcut to Opera, double-click on Opera.exe in one of the install directories, or run Opera.exe with the full path from Start-Run. The only work-around I've found is to right-click Opera.exe or a shortcut, and click "Run as administrator". This starts Opera, and it appears to work normally. Opera seems to be the only program so affected. I've checked Firefox and a few other (non-browser) programs, and they work normally. When IE starts instead of Opera, there are always two instances of iexplore.exe started, and they both crash before I can do anything else. IE also crashes if I try to start it from its own shortcut, but I don't know if that only started today, since I hadn't used IE for a few weeks. Does anyone know what might cause this and how to fix it? It's possible my PC has a virus, but BitDefender (for which I have automatic updates enabled) hasn't detected anything.

• Barriers to IPv6 deployment: addressing

  - by sysadmin1138

  There are several things that are keeping IPv6 deployment from being a topic of active discussion here at my work. There are the usual technical issues, but one non-technical one appears to be a major stumbling block on the path to actually getting a deployment project going. Addresses, memorizing of. Specifically, IPv4 addresses are comprehensible, and IPv6 addresses just look like a big long string of hex. The human mind has real trouble memorizing lists of more than 7-8 items, and an IPv4 address (192.168.231.148) has four items in it which makes it easy for us to memorize. A fully populated IPv6 address has not only 8 sections, but each section has 4 hex digits in it. IPv6 addresses were not designed for memorization. To the technician who knows that the DNS server is at 192.168.42.42 (or more likely "42.42", since the company prefix is likely memorized), the idea of memorizing an IPv6 address fills them with dread. Which in turn makes them much less enthusiastic about participating in an IPv6 deployment project. Because of how our network works we're not fully dynamic in terms of v4 addressing. We have several to many subnets that are entirely statically assigned for a variety of reasons, chief among them being that the overhead of static DHCP assignments is perceived as being too great. Also, some devices still aren't smart enough to pull DNS addresses out of DHCP while also having a static assignment, and therefore require manually configured DNS settings. Therefore, some v6 address memorization will have to be done. We're not under any mandate to get v6 out the door, so we don't have pressure from the top. However, it is time to start prepping our infrastructure to handle IPv6 even if we don't convert wholesale. For those of you who have been in IPv6-land for a while, what short-cut methods do you use to discuss or keep track of subnets and specific/critical IP addresses? If I can help reduce some of the dread surrounding IPv6 we might get the project going.

• windows 7 turns off itself everyday at about 9am

  - by Radek

  I was given this comp at work and after a week or so this strange thing started to happen in the middle of doing something :-( It turns off itself at about 9.10am every morning Just once a day and it works fine after it had it little nap. it happens both if the comp was on all night or I turned it off before leaving the office. I tried to swapped the memory as I was told that there was an issue with memory. But moving or removing any memory did not make any difference. I am not aware that I would install any program that could cause that. I installed AVG and set it up to do every day scan about 8am + if restart is needed it requires user confirmation. 'The Software Protection service has stopped' few minutes before it turned off itself but it happened also at other times without the computer turned off. I turned off Windows automatic updates as the first thing when I got the comp configuration Windows 7 Ultimate Intel Core2 Quad Q9550 at 2.8GH, 8GB RAM ST31000528AS Barracuda 7200.12 SATA 3Gb/s 1TB Update Below message are logged when I turn the comp on again.

• Partitioning & Linux

  - by Zac

  Every tutorial on Linux-based partitioning schemes (or, just partitioning in general) will tell you that a PC can have either 4 primary partitions, or 3 primaries and 1 extended. They will all also tell you that Linux (in my case, Ubuntu) can be installed on either. It's also come to my attention that it is not too atypical for FHS directories, such as usr/, tmp/, etc/, home/ or var/ to be mounted separately on other partitions. Several questions I am unable to find the answers to, purely for my own edification: (1) By "PC", are we really talking about common PC disk types, like IDE or SATA? I guess I'm wondering why PC uses are limited to 4 primaries or 3 primaries + 1 extended (2) I'm choking on some basic OS concepts: it is said that a partition can be mounted by a file system or an OS. So I assume this means I can somehow instruct Ubuntu to mount to 1 partition, and then any part of, say, ReiserFS, to be mounted to another partition? How? (3)(a) What about creating swap partitions? Is there too much of a good thing with swap partitioning? If I have 4GB RAM over 320GB disk, what should my swap partition size be, and why? (3)(b) Are swap files the only way to create swap partitions? Wouldn't a Linux partitioning utility allow me to define a partition as being for virtual memory only? (4) Why are partitions limited to being "mounted" by just OSes and file systems? Why couldn't I write a program to take up its own, say, 512 MB partition, and then have it invoked or uses by an OS installed on another partition? Thanks for shedding any light here... not critical that I know this stuff, but it's got me thinking incessantly. And when I think incessantly, I...can't......sleep....

• Exchange 2010 Hub Transport Role Fails - Registry Keys Missing?

• Building vs buying a server for an academic lab [closed]

  - by Roy

  I'm looking for advice on the classic build vs buy question. We need a new linux server to run Matlab computation on in our lab (academic). Matlab parallel computing toolbox licence allows up to 12 local workers so we are aiming at a 12 core server with 4GB memory per core (total of 48gb). The system will have an SSD for the OS and a raid-5 (4x2tb) for data. I looked around and found a (relatively) cheap vendor, Silicon Mechanics, that offers a system to our liking (specs below) for $6732. However, buying the components from newegg cost only $4464! The difference is $2268 which is 50% of the base cost. If buying from a company can be thought of as a sort of insurance, basically my premiums are of 50% of the base cost which to me sounds like a lot. Of course any downtime is bad, but the work is not "mission critical", i.e. if it takes a few days to fix it when it breaks its no the end of the world. If it takes weeks to months then its a problem. If it breaks 2-3 times in 3 years, not too bad. If it breaks every month not good. In term of build experience, I set up a linux cluster in grad school (from existing computers) and I build my home pcs but I never built a server before. The server components I'm thinking about: 1 x SUPERMICRO SYS-7046T-6F 4U Tower Server Barebone Dual LGA 1366 Intel 5520 DDR3 1333/1066/800 ($1,050) 12 x Kingston 4GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) ECC Unbuffered Server Memory ($420) 2 x Intel Xeon E5645 Westmere-EP 2.4GHz LGA 1366 80W Six-Core ($1,116) 4 x Seagate Constellation ES 2TB 7200 RPM SATA 6.0Gb/s 3.5" ($1,040) 1 x SAMSUNG Internal DVD Writer Black SATA ($20) 1 x Intel 520 Series 2.5" 180GB SATA III MLC SSD $300 1 x LSI LSI00281 PCI-Express 2.0 x8 MD2 Low profile SATA / SAS MegaRAID SAS 9260CV-4i Controller Card, $695

• Rebuilding LVM after RAID recovery

  - by Xiong Chiamiov

  I have 4 disks RAID-5ed to create md0, and another 4 disks RAID-5ed to create md1. These are then combined via LVM to create one partition. There was a power outage while I was gone, and when I got back, it looked like one of the disks in md1 was out of sync - mdadm kept claiming that it only could find 3 of the 4 drives. The only thing I could do to get anything to happen was to use mdadm --create on those four disks, then let it rebuild the array. This seemed like a bad idea to me, but none of the stuff I had was critical (although it'd take a while to get it all back), and a thread somewhere claimed that this would fix things. If this trashed all of my data, then I suppose you can stop reading and just tell me that. After waiting four hours for the array to rebuild, md1 looked fine (I guess), but the lvm was complaining about not being able to find a device with the correct UUID, presumably because md1 changed UUIDs. I used the pvcreate and vgcfgrestore commands as documented here. Attempting to run an lvchange -a y on it, however, gives me a resume ioctl failed message. Is there any hope for me to recover my data, or have I completely mucked it up?

• How to track which process is failing logons?

  - by Massimo

  Windows Server 2003, VMWare VirtualCenter 2.5. Something is continuously trying to log on to VirtualCenter using a disabled domain account; the failed logon attempts are logged by VirtualCenter in its own logs and by Windows in the Security event log. This happens roughly every minute or two. The source of the logon attempts is 127.0.0.1, so it must be some process running on the server itself. There are no services running as this user account and no scheduled jobs on the system. The task manager doesn't show any proces running under this account, either. The user account's name is nowhere to be found in the Registry. But some process is trying to use it, and failing. It probably is not some critical process, as everything looks fine; it could be something that was installed long ago and forgotten there. Whatever it is, it probably is running under another user account (possibly a system one), but is trying to log on to VC using those credentials, which are probably saved in some configuration file, since they're not stored in the Registry. How can I track which process is trying (and failing) those logon attempts, either using Windows or VirtualCenter?
