Title: A little RAID Help?
Post by: gbentley on May 16, 2011, 03:03:36 PM

Just installed new larger [300GB] SCSI drives to repalce some old 73GB ones. Did them one at a time and everything seemed to go ok [new discs detected, raid resize event completed fine]

Now I have come to grow the discs using these lines from howto ;

mdadm --grow /dev/md2 --size=max
pvresize /dev/md2
lvresize -l +100%FREE main/root
ext2online -C0 /dev/main/root 

Line 1,2 as expected but line 3 reports ;

Volume group "main" not found

[root@server log]# cat /proc/mdstat
Personalities : [raid1]
md2 : active raid1 sda2[0] sdb2[1]
      292856832 blocks [2/2] [UU]

md1 : active raid1 sda1[0] sdb1[1]
      104320 blocks [2/2] [UU]

unused devices: <none>
[root@server log]#

Any help appreciated :)
