            Bug ID: 1434302
           Summary: Move spit-brain msg in read txn to debug
           Product: GlusterFS
           Version: 3.8
         Component: replicate
          Keywords: Triaged
          Assignee: bugs at gluster.org
          Reporter: ravishankar at redhat.com
                CC: bugs at gluster.org
        Depends On: 1433838



+++ This bug was initially created as a clone of Bug #1433838 +++

I am seeing a lot of messages in qe/customer logs where read_txn
    complains that file is possibly in split-brain because of no readable
    subvol being found, does inode refresh and then there is no split-brain
    message post the inode refresh. This means that a lookup was not issued
    on the indoe to populate 'readable' or it can mean one brick is source
    for data and the other for metadata, making readable to be zero (because
    readable=intersection of (data,metadata readable) since commit
    7a1c1e290470149696.

    Since we anyway log actual split-brains post inode-refresh, move this
    message to DEBUG log level.
