dht: "replica.split-brain-status" attribute value is not correct
Problem: In a distributed-replicate volume attribute "replica.split-brain-status" value does not display split-brain condition though directory is in split-brain. If directory is in split brain on mutiple replica-pairs it does not show full list of replica pairs. Solution: Update the dht_aggregate code to aggregate the xattr value in this specific condition. Fix: 1) function getChoices returns the choices from split-brain status string. 2) function add_opt adding the choices to local buffer to store in dictionary 3) For the key "replica.split-brain-status" function dht_aggregate call dht_aggregate_split_brain_xattr to prepare the list. Test: To verify the patch followed below steps 1) Create a distributed replica volume and create mount point 2) Stop heal daemon 3) Touch file and directories on mount point mkdir test{1..5};touch tmp{1..5} 4) Down brick process on one of the replica set pkill -9 glusterfsd 5) Change permission of dir on mount point chmod 755 test{1..5} 6) Restart brick process on node with force option 7) kill brick process on other node in same replica set 8) Change permission of dir again on mount point chmod 766 test{1..5} 9) Reexecute same step from 4-9 on other replica set also 10) After check heal status on server it will show dir's are in split brain on all replica sets 11) After check the replica.split-brain-status attr on mount point it will show wrong status of split brain. 12) After apply the patch the attribute shows correct value. > Change-Id: Icdfd72005a4aa82337c342762775a3d1761bbe4a > Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> > Reviewed-on: http://review.gluster.org/15201 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > (cherry picked from commit c4e9ec653c946002ab6d4c71ee8e6df056438a04) Change-Id: Ia5234e8a2291a7e8a7211c82368f4df1c99fa099 Backport of commit c4e9ec653c946002ab6d4c71ee8e6df056438a04 BUG: 1375099 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> Reviewed-on: http://review.gluster.org/15466 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
