[Gluster-users] changing replication count without remounting

We have a setup that uses the gluster clients on the nodes where the
storage is located
for a replicated file system.

Is there a way to expand the replica count and not have to remount the
volume on the other nodes or delete/re-create the volume?

Currently we do the following:
gluster peer probe $clusteraddr
mount -t glusterfs $clusteraddr:$global_volume $MOUNT_POINT

get some data....
echo 'y' | gluster volume stop $global_volume
echo 'y' | gluster volume delete $global_volume

gluster volume create $global_volume replica $numreplicas node1:back_store
node2:/back_store node3:/backstore
gluster volume start $global_volume
mount -t glusterfs localhost:$global_volume $MOUNT_POINT
find $MOUNT_POINT -print0 | xargs --null stat >/dev/null

Then on the other nodes we have to
mount -t glusterfs localhost:$global_volume $MOUNT_POINT
