            Bug ID: 1724184
           Summary: Thin-arbiter: SHD takes lock and inspects the state on
                    TA during every index crawl
           Product: GlusterFS
           Version: mainline
            Status: ASSIGNED
         Component: replicate
          Assignee: ksubrahm at redhat.com

                CC: bugs at gluster.org
  Target Milestone: ---
    Classification: Community



Description of problem:

For thin arbiter volumes, even if there are no entries needing heal, SHD will
take a lock on TA in AFR_TA_DOM_NOTIFY domain and gets the state and then
unlocks. This will lead to invalidation of cached information on clients about
the bricks state even though there is no pending heal. This happens during
index crawl at every heal-timeout interval.

SHD should not take the lock on TA and invalidate the cached data on clients if
there is no pending heal.
