current Lustre release: 2.1.5 recently upgraded from 2.1.3
OS: Rhel5 (server), Rhel6 (clients),
[...] the /mountpoint/.lustre (fsname=test) directory has been accidentally
moved to a different place on a Lustre client with Lustre mounted.
Later on, I rebooted the system and tried to mount the mdt (fsname=test) on
the mds again, which wasn't possible anymore. The mgs and other mdt's on
the same system were still fully operational.
I tried to regenerate the Lustre configuration logs, with no luck...
The solution was to mount the mdt (fsname=test) via -t ldiskfs on the mds.
mount -t ldiskfs /dev/dm-4 /mnt/MDT4
now, I changed to the ROOT directory and moved the .lustre directory back
[root@xxx ROOT]# pwd
[root@xxx ROOT]# ls -al
drwxr-xr-x 5 root root 4096 Apr 22 16:24 .
drwxr-xr-x 8 root root 4096 Jan 27 12:19 ..
drwxr-xr-x 2 root root 4096 Jan 27 12:19 .lustre
drwxr-xr-x 2 root root 4096 Apr 22 16:24 nobackup
It solved the problem and I was able to mount the mdt (fsname=test) with
the -t lustre option again.

What version of Lustre are you running? Also, did you remove this
directory with Lustre mounted on a client or with the MDT mounted locally
