    Description

      After a failover, lfsck is started.
      2016-11-04 15:18:59,065:fsmgmt.fsmgmt:INFO lfsck started on lola-8
      lfsck never completes.
      2016-11-06 01:08:25,976:fsmgmt.fsmgmt:INFO lfsck still in progress for soaked-MDT0000 after 122865s
      Examining the logs, we see that the connection to OST0002 is going up and down, orphans cannot be cleaned up.
