This happens during a full Zimbra backup of certain accounts to /mnt/glusterfs/backups The first stage of the backup copies indexes and primary storage to /mnt/glusterfs/backups/tmp All of this data resides in local storage and the writing to gluster is successful. The next stage copies secondary storage to /mnt/glusterfs/backups/tmp This fails in the following way: Brick1 hangs with no errors Brick2 hangs with no errors Zimbra client hangs with no errors second client loses connectivity The second client bails after 2 min but cannot connect The Zimbra client never bails I then restart the bricks After both bricks are restarted, the second client reconnects and a hung df -h completes Zimbra client stays in a hung unconnected start ls -l /mnt/glusterfs hangs Only way is reset is kill -9 pidof glusterfs umount /mnt/glusterfs glusterfs Post mortem examination of /mnt/glusterfs/backups/tmp shows that a few files have the written from the secondary storage volume. I this can over 15,000 files should have been written. Note: this only happen with large email boxed with some large >10M files. Note: with patch-247 the zimbra client would seqfault. With 249 it just hangs in unrecoverable state.
