[Lustre-discuss] Need help

[Mervini, Joseph A]

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 at 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 at amds1 ~]# tunefs.lustre /dev/disk/by-label/scratch2-MDT0000 
checking for existing Lustre data: found CONFIGS/mountdata

exiting before disk write.

I am really stuck and could really use some help.

Thanks.
