happens only from healing code of afr/ec. And this can only happen if the source brick doesn't have gfid, which doesn't seem to match with the situation you explained.

more thing that I noticed was when the attributes were manually set when glusterd was up then on starting the volume the attributes were again lost. Had to stop glusterd set attributes and then start glusterd. After that the volume start succeeded.</span><u></u><u></u></p>

<p class="MsoNormal"> We faced an issue in the production today. We had to stop the volume and reboot all the servers in the cluster. Once the servers rebooted starting of the volume failed because
the following extended attributes were not present on all the bricks on 2 servers.
