           Summary: gluster-block profile needs to have strict-o-direct
           Product: GlusterFS

+++ This bug was initially created as a clone of Bug #1485962 +++

Description of problem:
    tcmu-runner is not going to open block with O_SYNC anymore
    so writes have a chance of getting cached in write-behind
    when that happens, there is a chance that on failover some
    data could be stuck in cache and be lost. So strict-o-direct should be on
