*Hi All, *
* We are seeing the same failure sporadically in three different places
(hotunplug disk). We think this is a race condition which was introduced to
OST with the the live storage migration test (lock on the disk is
preventing the hotunplug). Test failed: [ 004_basic_sanity.hotunplug_disk]
