• Centos expanding directory

  - by Ansell Cruz

  I currently have a file server, all the files are installed in /usr/local/nginx/html/. The setup is 1 hard disk with 1TB of data. This 1TB of storage is all used up. I asked the guys to add 2 HDDs with 2TB each. This new HDDs will be used for new storage of files. Now, if I mount this 2 new HDDs into /usr/local/nginx/html/, the current files in there will be deleted. My goal is to expand the storage in /usr/local/nginx/html/ without losing data in it. Would this be possible?

• Monitoring over Time with Nagios: How?

  - by David

  Nagios in its standard usage monitors with point-in-time checks: either something is - or is not - true. Other tools like SGI's PCP, HP's MeasureWare, and SEC provide monitoring over time - monitoring things like average disk access time over the last five minutes, or other similar items. Is there anything like this for Nagios? I'm already running NDOUtils, which seems like a natural source for such data. I'd like to have something that would monitor and fire off alarms based on a time-based check using historical data. Is there anything like this for Nagios?

• SQL Server Transaction Log RAID

  - by Eric Maibach

  We have three SQL Server servers, and each server has a about five or six databases on it. We are in the process of moving these servers to a new SAN and I am working on the best RAID configuration. Currently all of the log files for all of the databases share a RAID array, there is nothing else on this RAID array except for the log files, but all of the databases use this same array for their log files. I have read that it is best to have log files on separate disks. But in our case I am not sure whether it would be best to have one big array with about 8 drives that all the log files are on. Or would it be better to create four two disk arrays and give some of the larger databases their own dedicated disks for their log files?

• Make a file non-deletable in USB

  - by MegaNairda

  Somebody used my USB drive and upon returning it to me, I found a autorun.inf that is undeletable. I tried changing it's file attribute which is only H (not even set as a system file) but it keeps on saying Access Denied. The USB is set on FAT32, upon asking my friend, he told me that he uses Panda USB Vaccine http://research.pandasecurity.com/Panda-USB-and-AutoRun-Vaccine/ How do they do this? Im trying to use some Disk Sector editor but have no idea which hex file they change to make this kind of file and make it deletable again. Formatting the drive removes it, but I'm curious as to how to be able to set those kind of file attribute.

• How to choose my own filename format for subscribed podcast files?

  - by meomaxy

  I subscribe to several podcasts where the filenames of the downloaded mp3 files have no particular pattern to them. When I copy the directory of accumulated mp3 files into my mp3 player, the files play in alphabetical order. What I really want is to play the files chronologically by release date. I currently use iTunes on Windows XP to download the files. What I do now is manually rename the files, adding the date in YYYYMMDD format to the start of each filename so that an alphabetical listing of files will correspond to their chronological order when I listen to them later in PocketTunes on my Palm Centro. Is there some way to get the release date into the filename automatically? If so, I could automate or possibly skip the file renaming step. I would switch from iTunes to something else if that would solve my problem. The file creation time on my local disk isn't a reliable indicator because sometimes I download a few days worth of content at one time, and the files don't necessarily get downloaded in chronological order.

• Making GRUB see software RAID 0 under Ubuntu 10.10 LiveCD

  - by unknownthreat

  I just installed Windows 7 recently, and I expect that it would alter GRUB and it did. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. (Software RAID 0) I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". So what now? How can we make GRUB see RAID 0 under Ubuntu 10.10 LiveCD?

• How to pass an argument to a Windows Scheduled Task with spaces in it

  - by Rodney

  I need to set up a Windows Scheduled Task. It accepts 1 parameter/argument which is a path and can contain spaces. My Scheduled task does not work - it "breaks" the parameter up at the first space. If I run it in the Command Prompt I can just wrap the argument in " " and it works fine, however, this does not work in the Scheduled Task UI. e.g. C:\Program Files\xyz\FTP File Transfer\FTPFileTransferTask.exe "C:\Program Files\xyz\The Interface\Folder Path" I have tried wrapping the argument with " " ' ' [ ] () and have tried filling in the spaces with %20, ~1 etc. with no luck. I know of one solution to make a bat file and use " " around my argument but I don't want to add more complexity. I tried it on Windows 7 and Windows 2008 Server and both failed. There seems to be no discussions on this?

• Full Backup & Restore for Windows Vista

  - by Thomas Matthews

  I'm looking for a freeware or low cost application that will backup everything, including registry on Windows Vista Home Premium and to restore from a CDROM disk. The destination is an external hard drive on USB 2.0. Searching on SuperUser and Stack Overflow show articles, but don't mention full backup of the registry and complete restore using CDROM. I would also like to have compressed output and incremental backups. One article mentions CloneZilla, but their web page says that the incremental feature is not supported. I am using Windows Vista Home Premium, Service Pack 1. I need to backup 200 GB onto a 230 GB drive and would like to have multiple backups (thus the need for compression). Other requirements: Single file restore Quality is more important than performance. Application must run on Windows Vista. Extra: Run as daemon or background task on 4 user system. Thanks

• What parameters to mdadm, to re-create md device with payload starting at 0x22000 position on backing storage?

  - by Adam Ryczkowski

  I try to recover from mdadm raid disaster, which happened when moving from ubuntu server 10.04 to 12.04. I know the correct order of devices from dmesg log, but given this information, I still cannot access the data. The superblocks look messy; the mdadm --examine for each disk is on this question on askubuntu By inspecting the raw contents of backing storage, I found the beginning of my data (the LUKS container in my case) at position 0x22000 relative to the beginning of the first partition in the raid. Question: What is the combination of options issued to "mdadm --create" to re-create mdadm that starts with the given offset? Bitmap size? PS. The relevant information from syslog when the system was healthy are pasted here.

• Scheduled service/script/batch file to move files on condition of other files with similar filenames in same directory on windows

  - by ilasno

  On Windows Server (Data Center? 2008?), i'm trying to set up a scheduled task that will: Within a particular directory For every file in it If there exists (in the same directory) 2 files with similar names (actually the same name with extra extensions tagged on, ie. 'file1.mov' would need both 'file1.mov.flv' AND 'file1.mov.mpg' to exist), then move the file to another directory on a different disk. Following is what i have so far for a batch file, but i'm struggling. I'm also open to another technique/mechanism. @setlocal enableextensions enabledelayedexpansion @echo off SET MoveToDirectory=M:\_SourceVideosFromProduction ECHO MoveToDirectory=%MoveToDirectory% pause for /r %%i in (*) do ( REM ECHO %%i REM ECHO %%~nxi REM ECHO %%~ni REM ECHO filename=%filename% REM SET CurrentFilename=%%~ni REM ECHO CurrentFilename=%CurrentFilename% IF NOT %%~ni==__MoveSourceFiles ( IF NOT x%%%~ni:\.=%==x%%%~ni% DO ( REM SET HasDot=0 REM FOR /F %%g IN %filename% do ( REM IF %%g==.

• Test/Dummy SMTP server for Windows

  - by geoaxis

  I would like to install a Test/Dummy SMTP server on a Windows 2008 server (virtual box). I just want to test my web application on the machine it self so I don't need the mails to go out on the internet, but just to be written to disk (so that I can verify that the mail function was indeed called and the correct data was handed over to SMTP) Can you recommend some tool. I guess starting your own SMTP server in python is an option. I am looking for a simple (ready to use) solution, targeted for tests systems. I will need to integrate it to automated tests (Selenium) at a later stage. Thanks

• Looking for a sketch program with an infinite canvas

  - by Nils Riedemann

  Hi there, I'm not quite sure if such questions are allowed on SU. I was just wondering whether there is a sketch program like Adobe Ideas for iPad that has an infinite canvas but for OSX. It need not be feature rich and all that. Very simple, just for sketching out some stuff without thinking about the space. I was thinking about some vector tool where I could infinitely zoom in and draw. I'm sure you get the idea of what I am looking for. Any hints? OS is OS X.

• Finding the file that is on a bad block on a HFS+ volume (debugfs for HFS+)

  - by Blair Zajac

  I have a drive in our iMac that has bad blocks, as booting from an Ubuntu 11.10 live CD and using ddrescue -f /dev/sda /dev/null finds them. I'd like to get the drive to remap them by writing to the blocks, say using hdparm --write-sector, but I don't want to do this without knowing what's in those blocks and finding the file that owns them, so I can restore the file from another source. I found fileXray but don't feel like spending $79 to map a block to a file and hfsdebug has been taken offline. Are there suggestions on a tool or technique to use? I looked at all the Ubuntu HFS+ packages to see if they could provide this info but nothing jumped out at me. BTW, I used Disk Utility to erase the empty space, but it didn't get any of the bad blocks to be remapped, according to smartctl -A.

• Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not a "handsome prince"!

  - by Jim Dobbs

  Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

• Installing 2 DDR3 Sticks in MB with 4 Slots

  - by The Sasquatch

  Hey everyone, I just put together my first system that uses DDR3 memory. The motherboard I got is an ASUS M4A77T/USB3 and it has 4 DDR3 RAM slots. Looking in the manual for the MB it doesn't say anything about how to install the RAM as far as matching the pairs goes. I have 2 4GB sticks of RAM, and whether I put the sticks next to each other (of the 4 RAM slots, there are two blue ones next to each other and 2 black ones next to each other) or space them apart, The BIOS still shows that I have 8GB installed. I have been getting an IRQL_NOT_LESS_OR_EQUAL BSOD error, and have read in some other places that it could be hardware/RAM related. Does the RAM need to go in the A1, A2 slots (different colored but both A), or the A1 B1 slots? (A1 B1 are both the lovely blue color.) Any help would be awesome. THANKS!

• How to perform diagnostics (stress test) on HP Smartarray Controller

  - by pepoluan

  At my office, we have a server that we suspect its RAID controller (HP Smartarray) is failing. A cold boot, however, does not indicate anything. Can anyone recommend me a method to stress-test the controller? Symptoms that makes me suspect a failing controller: Disk access getting slower, queue getting longer Running dmesg on the XenServer console I see many messages similar to this one: end_request: I/O error, dev tda, sector 253655584 (the sector number is never the same) When we move the VM to another physical host, we no longer see the above message Running idle (without any running VM), the dmesg no longer emit the above message A search on Google indicated that the above message is most commonly associated with a failing SmartArray controller. How can I be sure that the SmartArray controller is failing?

• Restoring Box Sync (box.com) using physical media after OS reinstall

  - by sjrm

  I have my Box Folder on a different drive ( D: ) than my Operating System Drive ( C: ) I follow these instructions to set the local folder on the second drive. https://support.box.com/hc/en-us/articles/200852947-How-Can-I-Change-the-Default-Folder-Location-for-Box-Sync- I had to format and reinstall Windows 7, leaving the other drive (D: ) untouched. now i reinstalled Box Sync, and directed it to the same location where i already have all my files. However, Box Sync renamed the folder to (Box ([email protected]) ) as a bckup, and is downloading everything again. As i have like 30Gb of files, and it takes many hour to download them, i just want to use the files that i already have in my local disk. i tried copying all files again to the new local Box Folder, but files started to get duplicated. Is there any way to avoid downloading everything again each time i reinstall my OS ? Thanks

• Freebsd 7.2: View firmware version for disks?

  - by Stefan Lasiewski

  I'm running FreeBSD 7.2, with Seagate Cheetah (Model ST####) drives. We are having some problems with the SCSI drives on these machines. Our vendor says that updating the firmware on the drives may fix the problems, and a firmware update did seem to fix some SCSI problems on another FreeBSD host. How can I view the firmware version of these drives? I tried some tips from nixCraft, but nothing has worked so far. In dmesg, I see the Make and Model, but In Linux, this information is often in /var/log/dmesg (Although /var/log/dmesg is sometimes out of date), or I often find this information with something like sudo lshw -class disk, lshal or dmidecode.

• Can a 32-bit RHEL4 userland work with a 64-bit kernel?

  - by James

  Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries? On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy: http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r. What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.) Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.

  This happens when I am booting up into windows, shutdown or things in which I access the harddrive excessively. It doesn't happen all the time. I have checked it with "Crystal disk Info" and it displays no problem, and shows HDD to perfectly fine. Should I be worried about my HDD? I have Hitachi HDD in laptop. Some times my harddrive temps reach upto 43C while watching movies or playing games. What are the normal temps, which are safe for HDD to operate and increase the lifetime of HDD. Thanks

• Splitting a drive which has layout as mirrored and type as dynamic

  - by shiva

  I have a C drive/volume in my server with layout = mirror and type =dynamic and status as healthy(boot,pagefile,crashdump). I have some questions regarding this configuration: I think it is a raid configuration.Please correct me if I am wrong. I read that, mirroring is nothing but raid-1 configuration. All my software and OS is in this drive. I want my software to be in a separate drive, but I am not sure if I can create a separate drive from the above mentioned c drive. I want to know: a. If I can do it and how ?(using disk management) b. If this is a right approach ?

• Trigger ZFS dedup one-off scan/rededup

  - by Jake Wharton

  I have a ZFS filesystems which has been running for some time and I recently had the opportunity to upgrade it (finally!) to the latest ZSF version. Our data doesn't scream dedup but I firmly believe based on small tests that we could gain anywhere from 5-10% of our space back for free by utilizing it. I have enabled dedup on the filesystem and new files are slowly being dedupified but the majority (95%+) of our data already exists on the filesystem. Short of moving the data off-pool and then recopying it back, is there any way to trigger a dedup scan of existing data? It doesn't have to be asynchronous or live. (And FYI there isn't enough room on the pool to copy the entire filesystem to another and then just switch the mounts.)

• My computer resets when i try to install Windows 7 (USB/DVD)

  - by Ranhiru

  I had a troublesome software starting up when Windows 7 was starting and i had no way to remove it because i couldn't log in to Windows. Not even safe mode. But i used Hiren's Boot CD to edit the registry to stop that software from starting up... But my efforts were not useful as Windows kept on going to an ultimate freeze just before the login screen should have been shown. And just freezes and I cannot do anything. So i decided heck with it and i now want to format the disk and reinstall a fresh copy of Windows 7. But now regardless of USB or DVD i use to boot the setup, it loads fine till you see the animating Windows and it just resets the laptop! Just plain resets!
