[Lustre-discuss] LBUG under 1.8.4

[Gary Molenkamp]

On Wednesday we had an OSS hang due to a disk controller lockup on one
of our lustre installs. Since then we've seen this error on the MDS:

lund-adm1 kernel: LustreError: 6923:0:(mds_open.c:1295:mds_open())
ASSERTION(!mds_inode_is_orphan(dchild->d_inode)) failed: dchild
b668006:144d828c (ffff8104651d9d20) inode
ffff81046e94a138/191266822/340624012

Message from syslogd@ at Fri Dec 17 02:05:54 2010 ...
lund-adm1 kernel: LustreError: 6923:0:(mds_open.c:1295:mds_open()) LBUG


We did an e2fsck on all OSS and the MDS which cleaned up some orphan
inode on the MDS and all of the OSS's were clean.   I also searched
through BZ but all I found on the error was a bug from 1.4.

Is a full lfsck needed here?  Any suggestions would be appreciated.
