Description krishnaram Karthick 2016-09-08 15:41:27 UTC

Description of problem:
Detach tier commit operation should not be allowed when detach tier start operation has gone into failed state. There might be files which are not moved from hot to cold tier when a detach tier operation fails. Allowing to commit the operation removes off the hot tier bricks, thereby making those data in hot tier inaccessible.

rpm -qa | grep 'gluster'
