That is right. If you stop a volume, you stop it. If you are using the FUSE client and need HA, set up the gluster server packages on the client and add it as a peer to the cluster. Not a brick, just a peer. Instead of mounting like "mount -t glusterfs gluster-server-1.example.com:/your-volume /mnt/point" you can then exchange "glusterfs gluster-server-1.example.com" with "localhost". In the case of the failure of this node, the volume will continue to run and the mount point should continue to work - presuming your Gluster volume is set up correctly.
