[lustre-discuss] missing option mgsnode

[Paul Edmon]

We have a filesystem that we have running Lustre 2.10.4 in HA mode using 
IML.  One of our OST's had some disk failures and after reconstruction 
of the RAID set it won't remount but gives:

[root at holylfs02oss06 ~]# mount -t lustre /dev/mapper/mpathd 
/mnt/holylfs2-OST001f
Failed to initialize ZFS library: 256
mount.lustre: missing option mgsnode=<nid>

The weird thing is that we didn't build this with ZFS, the devices are 
all ldiskfs.  We suspect some of the data is corrupt on the disk but we 
were wondering if anyone had seen this error before and if there was a 
solution.
