Reinstall gluster server or upgrade is a dangerous task before it it's
better to backup /etc/glusterfs /var/lib/glusterd.
/var/lib/glusterd/glusterd.info contains the uuid of current server
and /var/lib/glusterd/peers contain it's peers
make sure above two files are all correct
If other servers status are fine then with only above configuration
files you can start current host and gluster volumes files will
automatically sync to current host.
Always remember backup
