Hello,

thanks for the info. Few questions inline below.

Sorry, I should have been more precise here. I was talking about the NFS 
glusterfs process which is started by glusterd on each brick if the NFS 
is enabled:
/usr/sbin/glusterfs -s localhost --volfile-id gluster/nfs -p 
/var/lib/glusterd/nfs/run/nfs.pid -l /var/log/glusterfs/nfs.log -S 
/var/run/c51406652e9e402c096101f64f8cba58.socket

This process doesn't get stopped even with the glusterfsd init.d script 
stop.

Stopping the whole volume is a bit too invasive. In case of failover 
setup one might not want to stop the whole volume, but just gracefully 
bring down a single brick (glusterd and all volumes attached to it). I 
guess the right way is to use both glusterfsd and glusterd init.d 
scripts for stopping and only glusterd for starting (assuming the volume 
wasn't stopped of course)?

Best regards
