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 checking for existing Lustre data: found CONFIGS/mountdata Reading CONFIGS/mountdata Read previous values: Target: scratch2-MDT0000 Index: 0 Lustre FS: scratch2 Mount type: ldiskfs Flags: 0x5 (MDT MGS ) Persistent mount opts: errors=panic,iopen_nopriv,user_xattr,maxdirsize=20000000 Parameters: lov.stripecount=4 failover.node=<failnode>@tcp1 failover.node=<failnode>@o2ib1 mdt.group_upcall=/usr/sbin/l_getgroups Permanent disk data: Target: scratch2-MDT0000 Index: 0 Lustre FS: scratch2 Mount type: ldiskfs Flags: 0x5 (MDT MGS ) Persistent mount opts: errors=panic,iopen_nopriv,user_xattr,maxdirsize=20000000 Parameters: lov.stripecount=4 failover.node=<failnode>@tcp1 failover.node=<failnode>@o2ib1 mdt.group_upcall=/usr/sbin/l_getgroups exiting before disk write.

I am really stuck and could really use some help.
