• Type: Bug

Description

we have seen multiple times that the Lustre MDT did not start on the
failover server. This happened for different file systems. Either the
configuration is wrong or something causes the failover server to hang
during recovery.
This happened on the file system HC3WORK at Dec 20 2013 but also on the
pfs2dat1 file system at Mar 10 and on multiple file systems
(pfs2wor1, pfs2dat2, pfs2dat1, HC3WORK) while I tried to deactivate ACLs
at Mar 17.
