Hi, Atin keeps giving the same answer: "it is by design" I keep saying "the design is wrong and it should be changed to cater for standby servers" In the meantime this is the workaround I am using: When the single node starts I stop and start the volume, and then it becomes mountable. On CentOS 6 and CentOS 7 it works with release up to 3.7.4. Release 3.7.5 is broken so I reverted back to 3.7.4. In my experience glusterfs releases are a bit of a hit and miss. Often something stops working with newer releases, then after a few more releases it works again or there is a workaround ... Not quite the stability one would want for commercial use, and thus at the moment I can risk using it only for my home servers, hence the cluster with a node always ON and the second as STANDBY. MOUNT=/home LABEL="GlusterFS:" if grep -qs $MOUNT /proc/mounts; then echo "$LABEL $MOUNT is mounted"; gluster volume start gv_home 2>/dev/null else echo "$LABEL $MOUNT is NOT mounted"; echo "$LABEL Restarting gluster volume ..." yes|gluster volume stop gv_home > /dev/null gluster volume start gv_home mount -t glusterfs sirius-ib:/gv_home $MOUNT; if grep -qs $MOUNT /proc/mounts; then echo "$LABEL $MOUNT is mounted"; gluster volume start gv_home 2>/dev/null else echo "$LABEL failure to mount $MOUNT"; fi fi I hope this helps.
