Since the built in kernel doesn't have the raid10 module for some reason, I would like to custom compile a kernel that does, and install with it. How would I go about doing this? Russ

We have a RHEL2 server that has had one of the drives in the raid array fail. I would like to do a full backup of the system before we replace the raided drive, in case the second drive decides to die during the procedure. What is the recommended way to back up a linux system? I was thinking of doing a snapshot, but the system is ext3 with no LVM. It has been suggested to hook up a usb

I just downloaded solaris. They have two versions, the split DVD that comes with two 1.2GB zipped chunks and an exe which is 1.2GB but uncompresses to the full 2.5+GB. I found some info on them here: http://www.nosltd.com/nosso.html Any idea how they achieve such great compression? Looks like they're using a proprietary algorithm and don't offer any downloads. Also looks like

I had a raid5 on an onboard Intel ICH9R chip under windows. Windows crashed, as it often does, and the array became degraded. At some point during the rebuild, I was doing some hardware maintanence and unplugged one of the drives, and forgot to plug it back in. When I booted up, the array came back as failed. I turned off the PC, plugged the drive back in and powered it back on, but the

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Are there any repositories for CentOS 5.5 that keep the latest MySQL versions? After enabling everything I can think off (CentOS, rpmforge, epel), I'm still only seeing 5.0.77-4.el5_5.4. 5.5 came out yesterday and 5.1 has been around for a while.

I just installed Windows 2008 x86_64 on Xen 3.2 that I compiled from source on CentOS 5.1. Are there any windows guest tools available that run shutdown when I issue xm reboot in dom0?

Hello all, The question is not necessarily CentOS-specific - but there are lots of bright people on here, and - quite possibly - the final implementation will be on CentOS hence I figured I'd ask it here. Here is the situation. I need to configure a Linux-based network load balancer (NLB) solution. The idea is this. Let us say I have a public facing load balancer machine with an public IP

So after troubleshooting this for about a week, I was finally able to create a raid 10 device by installing the system, copying the md modules onto a floppy, and loading the raid10 module during the install. Now the problem is that I can't get it to show up in anaconda. It detects the other arrays (raid0 and raid1) fine, but the raid10 array won't show up. Looking through the logs

We have an application that was build on a windows platform that expects a case insensitive file system. Is there a way to set one up in CentOS? NTFS should work, I think, but I feel uneasy using that under Linux. Russ

So when I couldn't get the raid10 to work, I decided to do raid5. Everything installed and looked good. I left it overnight to rebuild the array, and when I came in this morning, everything was frozen. Upon reboot, it said that 2 of the 4 devices for the raid5 array failed. Luckily, I didn't have any data on it, but how do I know that the same thing won't happen when I have

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm working with XenServer 5.5u2, which is basically CentOS 5. I'm having trouble creating a partition. I should still have free space in the extended partition, but it won't let me create any more logical partitions. Is there anything I'm doing wrong or is this a bug in fdisk?

Is there such a filesystem available? It seems like it wouldn't be too hard to implement... Basically do things on a block by block basis. Store md5 of a block in the table, and when writing a new block, check if the md5 already exists and then point the new block to the old block. Since md5 is not guaranteed unique, might need to do a diff between the 2 blocks and if the blocks are indeed

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am looking to set up a CentOS server for hosting a high traffic PHP site (specifically Drupal 6). I am trying to figure out what's the best way of setting up PHP. The standard mod_php seems to not be a good solution, as it requires apache to be in the prefork configuration, due to PHP not being thread safe. Something like mod_fcgi seems to be

Hi guys Has anyone have any workarounds with Internet Explorer 6 not displaying the mailbox on Outlook Web Access properly? My specs: Wine 0.9 on FC4, IE6 installed using ies4linux The problems (as I can see): the right-click context menu on the mailbox doesn't work (it doesn't display anything) and the compose email interface is missing the place where you can actually type your mail

I have recently upgraded from NexentaStor 2 to NexentaStor 3 and somehow one of my volumes got corrupted. Its showing up as a socket. Has anyone seen this before? Is there a way to get my data back? It seems like it''s still there, but not recognized as a folder. I ran zpool scrub, but it came back clean. Attached is the output of #zdb data/rt 2.0K sr-xr-xr-x 17 root root 17 Jul

I'm running CentOS 5.1 with all updates, and the xen kernel. For some reason the OS is not seeing the full amount of ram. #uname -a Linux CentOS-VM-A 2.6.18-53.1.21.el5xen #1 SMP Tue May 20 10:03:27 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux # free total used free shared buffers cached Mem: 6104064 3445136 2658928 0 1412236

I'm trying to back up our svn repositories, and I found a nice little backup command line bzip's the backup and creates the md5 hash all in one: svnadmin dump --deltas /repo |bzip2 |tee dump.bz2 | md5sum >dump.md5 The problem is I need to split the backups, so this doesn't really work. Is there perhaps another way of piping things to allow for splitting of the backups?

I'm trying to use the CentOS server for windows backups. I want to use rsync to get the data over there. I downloaded cwrsync, but I'm having issues getting it to work. I keep getting: "Disconnecting: Timeout, server not responding." Has anyone seen anything like this? Here is a transcript: C:\Documents and Settings\Russ>rsync -vvvvvvv /cygdrive/c/temp/xr backup-db

I successfully installed CentOS on 3ware 9650SE controller. Due to some issues with compatibility with my motherboard, I replaced it with a 9690SA. Now the system won't boot (although interestingly enough, it find the boot menu fine, just won't boot past a certain point in the bootup phase. I thought I would reinstall, but anaconda doesn't find the raid array. 3ware does have

I'm using VMWare Server 2 RC1 to on top of CentOS 5.2 x86_64 running a CentOS 5.2 i386 guest. I have enabled VMI in VMware, so I guess it won't let me install if VMI wasn't available in the kernel? How do I know whether VMI is supported/enabled and what performance benefits can I expect from it? I'm still not getting full hard drive speeds (only getting about 1/3 when using
