RAID on Red Hat Linux 7.2

Hi all

I have an old Compaq DL380 (G1) server with 4 hard disks. It is running Red Hat Linux 7.2

One of the disks died. I didn't build the box myself. How would I determine if software RAID was configured? I had a look a /etc/fstab, but it's only referring to ida/c0d0

The /var/log/messages file is logging "non fatal" errors on ida/c0d0.

Thanks

Check if software raid is setup. Have a look in the Red-Hat Documentation on how you should setup this.

Thanks for that. However, the documentation you referred me to only contains the "graphical configuration" instructions for RAID and it's "during installation" and not "after installation" instructions.

I'm using software RAID (mirroring) on my Linux box. If I run df, I see this:

Code:
$ df -k
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/md0               5036160    111016   4669320   3% /
df: `/proc/bus/usb': Permission denied
/dev/hda9              1296568     37360   1193344   4% /boot
/dev/md1              18136968   1455148  16681820   9% /home
/dev/md2              40313848  12277432  25988540  33% /usr
/dev/md3              10072680    764916   8796100   9% /var

And my vstab output looks like this:

Code:
none /dev/pts devpts mode=0620 0 0
/dev/md1 /home ext3 defaults 1 2
/dev/hdb /mnt/cdrom auto user,iocharset=iso8859-1,codepage=850,noauto,ro,exec 0 0
/dev/scd0 /mnt/cdrom2 auto user,iocharset=iso8859-1,codepage=850,noauto,ro,exec 0 0
none /proc proc defaults 0 0
/dev/md2 /usr ext3 defaults 1 2
/dev/md3 /var ext3 defaults 1 2
/dev/hda5 swap swap defaults 0 0
/dev/hdc5 swap swap defaults 0 0

The /dev/mdn are the "Metadevices".

It's been a while since I set mine up but from your fstab output, I'd say you were not running a software RAID.
