raid1 disk status

dindome · 02-13-2007, 03:04 PM

I have created software RAID1 with LSI Logic utility on
HS21 blade that has redhat OS. I am new to linux and I am trying to find out the equivalent of AIX commnad lsvg -p volumegroup for Linux. I have used vgdisplay, however I cannot tell whether my disks are mirrored. Thanks.

Hi.

I have used this on RHEL4/U4:

Code:

$ cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb2[1] sda2[0]
      312464128 blocks [2/2] [UU]

md0 : active raid1 sdb1[1] sda1[0]
      104320 blocks [2/2] [UU]

unused devices: <none>

this also provides status when you are re-syncing ... cheers, makyo
