similar to: Software RAID: on same IDE port or on different ones?

I have some old rack boxes which are going to get some bigger harddrives (IDE/ATA, not SATA) in Spring and I'm wondering if I should put two disks in them and use them as RAID 1 (software RAID). Objective being that the machine can hopefully carry on after (one) disk failure (including rebooting). I don't have any experience with software RAID. Can I do this during the normal CentOS

I just replaced two md-raided (RAID1) disks with bigger ones and decided to check out how far I get with them when I put them in another machine. The kernel boots and then panics when it wants to mount the root filesystem on the disk. md: Autodetecting RAID arrays md: autorun md: autorun DONE < not sure if this means it was successful or failed, I rather think it failed because it

CentOS 5, original kernel (xen and normal) and everything, Linux RAID 1. I rebooted one of my machines after doing some changes to RAID/LVM and now the two RAID partitions that I made changes to are "gone". I cannot boot into the system. On bootup it tells me that the devices md2 and md3 are busy or mounted and drops me to the repair shell. When I run fs check manually it just tells

It seems I can't smarm monitor disks on RAID controllers? I tried on several machines with two different controllers and on all I get this when starting up smartd: Jul 27 14:36:43 c1 smartd[5944]: Opened configuration file /etc/smartd.conf Jul 27 14:36:43 c1 smartd[5944]: Configuration file /etc/smartd.conf parsed.

Is there a program on CentOS which will sort my passwd/group etc. files by username or uid/gid? On Suse I can do this with a sysconfig switch and Suseconfig, is there something similar on RH-based systems?

This is my first major version update after using a local repo. It seems that before I can "yum update" I have to fetch the complete new 5.2 base? Is this correct? When I run yum update it now fails with various strange dependency errors although all the updates are synced. When I change to using the original repo file it wants to download many many more and shows a lot of files that

My update to 5.2 fails on one machine because of this error: Transaction Check Error: file /etc/init.d from install of chkconfig-1.3.30.1-2 conflicts with file from package AcronisAgentLinux-9.5.8076-1 file /etc/init.d from install of chkconfig-1.3.30.1-2 conflicts with file from package TrueImageAgent-9.5.8076-1 Obviously, both packages created (completely unnecessarily) the /etc/init.d

Using CentOS 5.1 with Xen 3.2. I'm trying to install a fully virtualized system for the first time and doing this with an old Suse 9.0 (this probably would run paravirtualized, maybe it won't run, anyway, because of hardware problems). I start with virt-manager and after choosing "fully virtualized" it presents me two options for install media: iso image and CD-ROM or DVD,

I have a machine on CentOS 5 with two disks in RAID1 using Linux software RAID. /dev/md0 is a small boot partition, /dev/md1 spans the rest of the disk(s). /dev/md1 is managed by LVM and holds the system partition and several other partitions. I had to take out disk sda from the RAID and low level format it with the tool provided by Samsung. Now I put it back and want to reassemble the array.

I converted a physical maschine running CentOS 4.6 to a Xen VM on a CentOS 5 host. Almost everything was running when I decided to rsync /lib and /usr a while later in order to get updated files and get the one or two non-working programs to work. There are differences because of the xenU kernel I didn't think about. I forgot to exclude rpm database and /lib/modules. Because the synced

I have a local mirror of CentOS5 base and updates. Now with 5 having become 5.1 and in case I just want to keep on updating (at the moment) is it enough that I update the mirror of updates or do I also need an update of the base repo?

The new virtual machine manager in Centos 5.1 displays some weird behavior here and I assume it's because the UUID of one running VM is the same as of a VM that is shut down. I used the same config file template for creating all my test VMs, so several have the same UUID. Didn't produce any problems with xm. But the new VM manager in Gnome shows active and inactive VMs and identifies

I took over a custom firewall script from my older Suse machines to my Dom-Us and it works just fine. Doing the same for Dom-0 immediately killed all traffic for the VMs. As there was no need before I had been dropping everything on the FORWARD chain. After ACCEPTing all for FORWARD my VMs are happy again. What's best practice on Dom-0, what do you do? Can I restrict the forwarding, in

The installed php on CentOS/RHEL is the CGI version. This means I should be able to get command line arguments with $GLOBALS[''argv''] or $_SERVER[''argv'']. That''s how the php documentation tells and how it works f.i. on Suse. However, on CentOS I get them only when I use the -n switch to php (no php.ini). The problem with -n is that php cannot find

What does the plus sign after the blocks value exactly mean in the fdisk output? Some research reveals that it indicates that not all the blocks are included in the fdisk value.

We are serving the mp3s with .nsv endings since that is what the oddcast plugin seems to send by default when mp3 is

All of a sudden yum hangs on a Centos 4.5 (updated to the latest patch before 4.6) when I try to use it. "clean metadata" didn't help. The output of -d5 shows it gets to the point of "Reading Local RPMDB" and then sits there. The process doesn't die, but doesn't seem to do anything from that point on. strace shows this: futex(0xb76dcae8, FUTEX_WAIT, 2, NULL I
