• How can I disable logging in Tomcat 7?

  - by WilliamMayor

  I have a Tomcat 7 server running in a VM that has very little disk space (20G). Over the course of a few days Tomcat will fill the space with logging info (usually about 15G before it runs out). I've tried turning down the log level (from INFO to SEVERE) in the logging.properties file, I've also tried sending the log info to /dev/null. It doesn't seem to work as I still get a full log directory after no time at all. Can I put a file size limit on the log files? Is something overriding the properties I'm setting? Where can I find this information? My Google Fu just returns information about logging from within an application using JULI.

• Reverse lookup of inode/file from offset in raw device on linux and ext3/4?

  - by lilinjn

  In linux, given an offset into a raw disk device, is it possible to map back to an partition + inode? For example, suppose I know that string "xyz" is contained at byte offset 1000000 on /dev/sda: (e.g. xxd -l 100 -s 1000000 /dev/sda shows a dump that begins with "xyz") 1) How do I figure out which partition (if any) offset 1000000 is located in?(I imagine this is easy, but am including it for completeness) 2) Assuming the offset is located in a partition, how do I go about finding which inode it belongs to (or determine that it is part of free space) ? Presumably this is filesystem specific, in which case does any one know how to do this for ext4 and ext3?

• Switching to Linux, Need backup help

  - by Stephen

  I have an existing Vista installation on my thinkpad x200 and I want to install Linux on my machine. I've done this several times already but I usually format the whole disk and dual boot on Windows and Linux. Which means I have to reinstall and reconfigure everything I had on Windows. What I want to do is backup my windows installation (into an image) and start a clean Linux installation, and run the windows image thru Vmware or Virtualbox. Whats the easiest way to do this? any free tools available? I've seen acronis but dont wanna buy it for a 1 time session only.

• Identify SATA hard drive

  - by Rob Nicholson

  Very similar question to: Physically Identify the failed hard drive But for Windows 2003 this time. Scenario: Four identical SATA hard drives plugged into motherboard (no RAID controller here) Configured as single drive in Windows as a spanned volume One of them is starting to fail with error "The driver detected a controller error on \Device\Harddisk3" How do you cross-reference Harddisk3 to the physical SATA connection on the motherboard so you know which drive to replace? I know replacing this drive will trash the spanned array requiring it to be rebuilt anyway so my rough and ready solution is: Delete the spanned partition Create individual partitions on each drive labelled E: F: G: and H: and work out which one is Harddisk3 Power down, remove each disk one at a time, power-up until the drive letter disappears But this seems a rather crude method of identifying the drive. The SATA connectors will be numbered on the motherboard but I appreciate this might not cross-match to what Windows calls them. Thanks, Rob.

• auspex LFS backups

  - by user1250465

  I have some backup tapes which existed on an AUSPEX file server. The backups were written to tape with the SunOs version of the CPIO command. Now that I need to restore them, (of course there are no more auspex servers in existance), the backups won't restore because the headers are not standard. I have dumped the tape images to disk. PAX, CPIO, and TAR cannot read the images. I've tried all of the CPIO format options. The errors I get are "name too long", "byte swapped in header", or just junk output. I can open up the images and read the contents of the files, but cannot restore the images. I have found that SunOs had a special header in CPIO V2.5 images. I have found the source for cpio, now I need definition of the SunOs header inside CPIO?

• How to get external 2.5 inch HD enclosure get recognised

  - by fireBand

  I am completely out of ideas. I have 2.5inch HDD from my old laptop, I have tried with 2 different HDD enclosures but my desktop does not recognize it. Not even showing in the disk management or BIOS. The HDD works fine if I use in a 3.5 inch enclosure with external power. I have tried 3 different Y USB cables. I have also got a 7 port self powered 2A USB hub. I have updated my chipset drivers as well. The problem is with my desktop , the enclosures work fine with my new laptop. Anything else that I should try? Thanks in advance.

• remove disks or other media press any key to restart

  - by Sam I am

  I'm having an issue regarding a disk imaging process. I have a WinPE image that will re-partition, the hard drive, and put a boot-able image on it. When I run the imaging process from an initial state, I get the following error remove disks or other media press any key to restart If I run the process subsequent times, It will work as desired, but I'm still interested in getting the process to work the first time. How do I figure out what's going on here? what should I be looking at? I'm a little bit out of my depth here, I don't know what to do next

• How can I improve performance over SMB/CIFS for an application that has poor write speeds?

  - by Jeremy

  I have a third party application that reads several large files and generates a third large file. Its performance is quite good when the generated file is stored on "local storage", i.e. either a direct attached or iSCSI-based disk. The source files that are read can be stored remotely on our NAS and accessed via SMB with little effect on performance. However, if we attempt to write the target file to any kind of SMB/CIFS share (Samba or Windows Server) the performance drops almost ten-fold. This is unacceptably slow in our case. Writing files to network shares is not otherwise slow. I can copy large files to SMB shares and get great performance - near what I would expect is possible given the disks and network in question. I have a theory that this application's problem with SMB shares has something to do with a lack of write caching over the share and perhaps lots of network roundtrips. Is this possible and is there anything that can be done about it?

• Why does diskpart set the volume attributes on all volumes?

  - by Nick

  I was trying to migrate a Win7 OS from a HDD to a SSD. I've created 2 partition with 1024KB offset, with diskpart: 100MB System Reserved and a 60GB for C:. I've cloned their contents using Easeus Disk Copy. I've loaded the Windows 7 Boot DVD, and wanted to use diskpart to drop the letter for the System Reserved partition and make it hidden. select volume 0 detail volume attribute volume set nodefaultdriveletter attribute volume set hidden These 2 attribute set commands actioned on both volumes (0 and 1, MSR and C:) instead of the selected one, and viceversa. I've tried to clear these attributes from volume 1, but it cleared them also from volume 0. Why does DiskPart have this behaviour?

• Allow READ access to local folders in 2003SBS AD

  - by Dan M.

  Have a SBS2003 client with a mess of a domain that is in process of being cleaned. But, for the life of me I cannot find a setting that will allow write access to the local hard disk for domain users with redirected profiles(to the server). This is needed only for one program that will not follow a symbolic link to the network path, instead it seems to be hard coded to the %appdata% folder but only on the c: drive.... So question is how can I allow "Domain users" write access to the local %appdata% directory? I have tried setting it manually on a machine but it kept resetting to RO no matter how many times I tried. Everytime I would uncheck the RO property it would reset sometime right after i hit OK. Thanks in advance! Dan

• 4TB HGST SATA drive only shows 1.62 TB in Windows Server 2012

  - by user136085

  I'm using a Supermicro X9SRE-3F motherboard with the latest BIOS and 2x 4TB drives connected to the on-board SATA controller. If I set the BIOS to RAID and create a RAID 1 array, the array shows up in the BIOS as 3.6TB. However when I boot Windows (on a separate RAID 1 array), the 4TB drives show up individually in disk manager as 2x 1.62TB drives. I could use Windows 2012 to set up software RAID 1, but when I set the BIOS back to 2x individual drives, they still show up in Windows as 2x 1.62TB drives. How do I access the full capacity of these drives? Thanks, Brian Bulaw

• Network backup for Macs and PCs - formatting question

  - by neilfein

  I'm trying to use a LaCie 2TB drive as an AirPort drive, for backup on a home network. We have one mac and two PC laptops. My plan is to create a Mac partition and a Windows partition. However, Disk Utility won't let me set the windows partition to Windows format; there's no option in the menu for it in the partition tab. Am I doing something wrong? Alternatively, is there a way to partition the drive with one partition that all three machines can see? We have a Mac G5 with 10.4 and two laptops with Windows 7. Thanks!

• VMWare Server lck file keeps coming back

  - by muncherelli

  I am running VMWare Server 2.0 on a Debian Lenny system as a host OS. I am getting this error when I try to start a Virtual Machine Cannot open the disk '/var/lib/vmware/Virtual Machines//.vmdk' or one of the snapshot disks it depends on. Reason: Failed to lock the file. So I looked around on the web and found that I need to delete the .lck folder and file in order to get this error This seems to happen any time I reboot my Debian Server. The Virtual Machines sometimes do not recover and this lck file is causing problems. Should I create a cron script that does a rm *.lck on each of my machines on reboot? Looking for any direction on how to resolve this. It seems when i do a "reboot" command it is maybe not gracefully shutting down the VMware containers so the lock files are still intact?

• How to resize root LVM partition in Fedora without LiveCD or Rebooting

  - by Cerin

  I have a virtual machine that recently had its disk image increased from 20GB to 50GB, and fdisk -l verifies that the VM can see this new size. Now I need to resize my root LVM partition to fill the extra 30GB. I've found several articles about resizing LVM, but the few that cover resizing the root partition all claim you need to boot from a LiveCD. Is there any way to do this without taking down the server? The server is critical, so I'd like to minimize downtime.

• SCSI vs SATA? Is SCSI "actually" better?

  - by earlz

  Well, I was talking with a guy about servers the other day. I was a bit shocked whenever I asked him if there was any significant difference between SCSI and SATA and why he always uses SCSI. (note, I'm not sure if by SCSI he meant SAS) He told me that SCSI is always faster and that the drives are always more reliable.. I mean, this seems like a bold statement. He told me something about how SCSI will always be faster than SATA because the OS sends the SCSI (controller?) a request to get a file and it will build the file inside of the SCSI controller, instead of searching all over the disk.. which I do not understand how that would work, so I figure it is BS. SAS and SATA currently have equivalent data rate speeds.. Is there any true backing for his reasoning that SCSI is always faster and more reliable than SATA?

• CPU fan turns on and off repeatedly without booting

  - by rnso

  My PC has suddenly stopped starting up. On checking with case open, the CPU fan starts running when the power is turned on, but it stops after about 2-3 seconds, restarts again after about 2-3 seconds and the loop is repeated. There is no beep and nothing appears on the screen. On searching the internet, I found there could be several reasons for this. I tried removing hard-disk, CD drive, tightening connections etc but of no avial. I also tried using a new power supply but the response is the same. Where could be the problem and how can it be solved? Thanks in advance.

• Solaris mounting partitions

  I'm trying to mount a partition in solaris 10... bash-3.00# mount /dev/dsk/c0t0d0s3 /data mount: /dev/dsk/c0t0d0s3 is already mounted or /data is busy As far as I know c0t0d0s3 isn't already mounted elsewhere, so what's really going on here?

• I want to version control my entire slice

  - by Tom

  I'm renting a slice (i.e., a VPS) from Slicehost. I've a spent a day or two filling up /usr with my favorite packages, /etc with configs and init scripts, and so on. Now I want to: save this whole setup somewhere (e.g., to load onto another machine). see what changes I've made to which files revert changes, tag revisions, and all that other good version control stuff Saving a disk image gives me (1), but not (2) and (3). Using Subversion (svn import / svn://someotherhost) might give me all three, but I expect problems if I actually try to check a project out into / and maintain .svn directories in root-owned areas. And to load my setup onto a fresh slice, I'd need to install an svn client on it first. Is there a good way to do what I want to do?

• Recommend a good DVD or BD replacement drive that can read older CD-R/DVD+R media?

  - by Irinotecan

  So I have a bunch of older CD-R (and a few DVD+R) discs that are either suffering from "bit rot", or a case of crappy no-name Chinese DVD drives being unable to read some or all of anymore. I just threw my last no-name DVD drive in the trash after it ejected a disk still spinning causing it to scratch to the point of being useless, so I'm looking for a replacement drive this time around with an eye for quality over a dirt cheap price. I'd prefer a BD drive, but I'll take any suggestions for good, reliable DVD or BD drives that people have reported having good success with for reading older burned media. Any takers?

• File corruption when copying different file on raid 1

  - by Stephan

  I have a RAID 1 configuration of 2 1TB drives on a Fedora 12 box. Most of what is stored there are video files that are numerical labeled. The problem I'm having is that I had one of the video files get corrupted. I copied a replacement from a backup and replaced the bad file and now it works fine. However, after doing this the next numbered file goes from 350MB to 200KB and all but about .5 second of video disappears. If I then replace that file it happens to the next one down the line. Ex: Replace corrupt file 1.avi and file 2.avi shrinks to 200KB. Replace now corrupted 2.avi and it works but 3.avi gets screwed up. I have run SMART tests on the drives and they report fine. Does anyone have any tests I can run to try to figure out what is going on? EDIT: It is a two disk software RAID 1 with an ext4 filesystem

• Windows 7, files reappear after deletion.

  - by HeavyWave

  I'm trying to delete some files from a folder. I've taken ownership of the files and the folder. When I delete these files Windows doesn't report any errors and deletes them. BUT, after I press F5 these files reappear again. There are no messages whatsoever, they are just undeletable. I know login off will help, but how do I fix it without going through the pain of closing everything down? P.S. Files disappear from the folder after aprox. 5 minutes. Update. Turns out my version of Windows did not properly upgrade from test version, so it had some weird disk drive issues.

• PC wont boot with more than 1 stick of RAM.

  - by Aidan

  Hi Guys, I've got the following computer and I've just put in a new CPU QX9650 and I've run into this problem since making this hardware change. Whenever I put more than 1 of my 4 sticks of ram into my machine it wont load an OS. It'll go through the BIOS but BSOD on windows load. It also wont let me install an OS from disk or boot into Linux. I've ran memtest with all 4 sticks in and I get 10k+ errors on test5. Each stick of ram on it's own is fine and functions properly. I only have problems when all 4 sticks are in the machine at the same time. System specs.. CPU: QX9650 Mobo: Asus P5B 2104 BIOS RAM: 2xPC25400 DDR2 , 2xPC2 6400 both OCZ. Is the problem on my end or is the CPU faulty?

• VMWare guest OS is not using full hard drive space

  - by syuusuke

  Hey everyone, I'm wondering if you can give me some insight on how to figure this out. I've recently virtualized a w2k3 server that had 10GB C:\ drive size. Once I finished virtualizing it, I expanded the disk to 20GB for C:\ and within guest OS (W2K3) computer management settings, you can see it recognizes as 20GB partition C:. But for some reason, if I opened windows explorer and see the properties of C:\, it will only show total size of 10GB. Does anyone know how to solve this or even had this problem before?

• How can I format a USB drive as FAT from a MacBook Pro?

  - by Edward Tanguay

  I plugged in a 250GB USB hard drive into my MacBook Pro and want to format it in FAT so I can transfer files back and forth between a windows machine. (My windows7 machine only formats in exFAT which my Snow Leopard 2.6.4 doesn't support until I do the update). So I want to format it on the mac. but when I right click on the drive, it gives me the options to eject, copy, but not to format. I can go into Disk Utilities, click on Partition, but the only option is the "Mac Journaled format". How can I Format my USB drive as FAT from my MacBook Pro?
