Hi,
I just upgraded our servers from RHEL 5.4 -> RHEL 5.5 and went from lustre
1.8.3 to 1.8.5.
Now when I try to mount the OSTs I'm getting:
[root@aoss1 ~]# mount -t lustre /dev/disk/by-label/scratch2-OST0001
/mnt/lustre/local/scratch2-OST0001
mount.lustre: mount /dev/disk/by-label/scratch2-OST0001 at
/mnt/lustre/local/scratch2-OST0001 failed: No such file or directory
Is the MGS specification correct?
Is the filesystem name correct?
If upgrading, is the copied client log valid? (see upgrade docs)
tunefs.lustre looks okay on both the MDT (which is mounted) and the OSTs:
[root@amds1 ~]# tunefs.lustre /dev/disk/by-label/scratch2-MDT0000

I am really stuck and could really use some help.
Thanks.
