    Description

      When the lustre servers have OST configured with multipath devices, there are I/O errors that can lead to a server crash.

      The following error appears in the system log:

      Mar 31 00:02:44 oss01 kernel: device-mapper: multipath: Failing path 8:160.

      Followed by several I/O errors
