I have a Mandrake 10 server with a 40gb boot drive and a three 200gb disk
software raid 5 array using reiserfs. A disk went bad; so i have replaced
it.
Doing the normal things to get it back up don't work:
[root@server root]#raidhotadd /dev/md0 /dev/hdg
....
# cat /etc/raidtab
raiddev /dev/md0
raid-level 5
chunk-size 128k
persistent-superblock 1
nr-raid-disks 3
device /dev/hdg1
raid-disk 0
device /dev/hdi1
raid-disk 1
device /dev/hdk1
raid-disk 2
so you replaced the first disk in the array?
raidtools are not capable of handling this.
switch to mdadm
echo "DEVICE partitions" >> /etc/mdadm.conf
mdadm -Esc partitions | grep ARRAY >> /etc/mdadm.conf
mdadm -ARs
mdadm -a /dev/md0 /dev/hdg1
mv /etc/raidtab /etc/raidtab.FOOBAR (this is important)
