This one is lustre over zfs.
Running tunefs.lustre with writeconf didn't seem to help either.
Still get the same messages trying to mount MDT, though
all pools have data.

Anjana,
Does this look similar - https://jira.hpdd.intel.com/browse/LU-4634 ?

Would it make sense to run
"tunefs.lustre --mgs --writeconf --mgs --mdt /dev/sda /dev/sdb" ?
The original mkfs command used to create the MDT was
mkfs.lustre --reformat --fsname=iconfs --mgs --mdt --backfstype=zfs
--device-size 131072 \
--index=0 lustre-mgs-mdt/mgsmdt0 mirror /dev/sda /dev/sdb
Not sure if both device names should be included or the zpool name.
The latest 2.5.x version also fails to mount MDT with similar
messages, though
zpool seems intact... is there anyway to get MDT to mount?
