gluster (graceful, reliable) services stop

ref/base: https://github.com/gluster/glusterfs/blob/master/extras/stop-all-gluster-processes.sh

also:

killall glusterfs glusterfsd glusterd before issuing shutdown or reboot. If it is a replica or EC volume, ensure that there are no pending heals before bringing down a node. i.e. gluster volume heal volname info should show 0 entries.

Seen something like that.

It looks like the processes are sent SIGKILL first and not SIGTERM by systemd. Maybe the glusterd.service needs some updates.

There is a script /usr/share/glusterfs/scripts/stop-all-gluster-processes.sh that can be used to shutdown gluster.
