[Gluster-users] Shutting down a server with no service disruption and Xen instance errors

[Torbjørn Thorsen]

Okay, so basically what Joe Julian said here:
http://www.gluster.org/pipermail/gluster-users/2013-September/037169.html
?

Just sending a TERM signal to the "glusterfsd" process using kill ?

I checked the init scripts, and they seem to only signal the "glusterd" process.
Could it be that the "glusterfsd" process aren't stopped gracefully by
the init script,
and they get killed hard when the server reboots ?

Is it so that if you do "service glusterfs-server stop", the
"glusterfsd" processes are stopped as well ?
