gluster-block: strict-o-direct should be on
Backport of https://review.gluster.org/18120 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. >BUG: 1485962 >Change-Id: If9835d914821dfc4ff432dc96775677a55d2918f >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> BUG: 1486122 Change-Id: If9835d914821dfc4ff432dc96775677a55d2918f Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: https://review.gluster.org/18126 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> Tested-by: Krutika Dhananjay <kdhananj@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
