We're experiencing a very sporadic issue where the client and MDS
appear to be out of sync for some time. See the example below. When
this occurs there are no errors on the mds or any of the oss's, but
errors on the client like:
Jun 14 13:37:14 bulldogi kernel: Lustre:
3374:0:(namei.c:235:ll_mdc_blocking_ast()) More than 1 alias dir
95854042 alias 2
Jun 14 13:37:14 bulldogi kernel: Lustre:

3374:0:(namei.c:235:ll_mdc_blocking_ast()) More than 1 alias dir
95854042 alias 2
What does this mean? I see a similar unanswered question on the
mailing list dated May 15th regarding this.
Lustre is not heavily used yet, healthy, and all devices are up.
This problem persists for about one minute before reporting correct information.
