Hi,
Does anybody encounter problem configuring software RAID 1 with FC2?
I have 2 identical HDDs, the 1st one where I install FC2 and the 2nd HDD is unformatted. Here is the error messages I got:
# mkraid /dev/md0 handling MD device /dev/md0 analyzing super-block disk 0: /dev/hda, 29316672kB, raid superblock at 29316608kB disk 1: /dev/hdc, 29316672kB, raid superblock at 29316608kB mkraid: aborted. (In addition to the above messages, see the syslog and /proc/mdstat as well for potential clues.) #
Here is error from log file:
kernel: md: could not lock hda. kernel: md: error, md_import_device() returned -16
# cat /proc/mdstat Personalities : md0 : inactive unused devices: <none>
# cat /etc/raidtab raiddev /dev/md0 raid-level 1 nr-raid-disks 2 nr-spare-disks 0 chunk-size 4 persistent-superblock 1 device /dev/hda raid-disk 0 device /dev/hdc raid-disk 1 #
Any comments and help would be appreciated. Thanks.

Needs to be /dev/hdaX and /dev/hdcY where X and Y are partitions. You need to partition hda and hdc using fdisk or cfdisk. Create partitions of type fd (Linux RAID autodetect). So it might look like this:
/dev/hda1 ext3 (/boot) 100MB /dev/hda2 swap (swap) 500MB /dev/hda3 fd (RAID partition) 6GB /dev/hdc1 fd (RAID partition) 6GB
then your /etc/raidtab would look like this:
device /dev/hda3 raid-disk 0 device /dev/hdc1 raid-disk 1
Make sense?

You apparently defined a raid 1 device during install, then used one of the raw drives to install. To eliminate the errors you will need to remove the raid device.
