Hi all,

on a 1.8.4 test system, I tried prepare for lfsck and got an error from

mds:~# e2fsck -n -v --mdsdb /tmp/mdsdb /dev/sdb2
e2fsck 1.41.10.sun2 (24-Feb-2010)
lustre-MDT0000 lustre database creation, check forced.
Pass 1: Checking inodes, blocks, and sizes
MDS: ost_idx 0 max_id 190010
MDS: ost_idx 1 max_id 179671
MDS: ost_idx 2 max_id 43436
MDS: ost_idx 3 max_id 97654
MDS: ost_idx 4 max_id 78973

MDS: num_osts = 5
mds info db file written
error: only handle v1 LOV EAs, not 0bd30bd0
e2fsck: aborted

The mdsdb file is created, but the OSTs can't use it:

oss:~# ...
Pass 6: Acquiring information for lfsck
error getting mds_hdr (3685469441:8) in /tmp/mdsdb: DB_NOTFOUND: No
matching key/data pair found

However, the stub mdsdb.mdshdr is acceptable for the OSTs, e2fsck goes
through and produces its ostNdbs, but then the lfsck fails on the
client, of course.

No traces of this error message on the internet, so I'm asking here.
General error / misconfiguration / bad e2fsprogs ?
