The root cause behind this problem seems to one I debugged a short while back. When we reboot. When we reboot gfs_serv1, so that we can unmount the bricks, we kill off the glusterfsd processes on it. At this point, as the tcp connection between the mount client on gfs_serv0 and the glusterfsd on gfs_serv1 breaks, the former makes portmap queries to the glusterd on gfs_serv1 to get the port number for glusterfsd. At this point, if glusterd is not aware that glusterfsd is dead, it is possible that glusterd will return the port number of the dead glusterfsd process. This will cause the portmap query to succeed, but no actual connection will be established between mount client and brick, and then updates to files on gfs_serv0 will not be immediately propagated to the replica on gfs_serv1. More details in the mail below: http://www.gluster.org/pipermail/gluster-users/2015-February/020770.html has all the technical details. GlusterFS 3.7.0 has been released (http://www.gluster.org/pipermail/gluster-users/2015-May/021901.html), and the Gluster project maintains N-2 supported releases. The last two releases before 3.7 are still maintained, at the moment these are 3.6 and 3.5. This bug has been filed against the 3,4 release, and will not get fixed in a 3.4 version any more. Please verify if newer versions are affected with the reported problem. If that is the case, update the bug with a note, and update the version if you can. In case updating the version is not possible, leave a comment in this bug report with the version you tested, and set the "Need additional information the selected bugs from" below the comment box to "bugs". If there is no response by the end of the month, this bug will get automatically closed. GlusterFS 3.4.x has reached end-of-life. If this bug still exists in a later release please reopen this and change the version or open a new bug.
