[Gluster-users] How to properly shutdown Gluster (glusterd *and* related processes)

[Guido De Rosa]

Hi, thanks for the replies!

My question, which originated this thread, raised from a Debian user
perspective: the package includes an init script which starts and
stops glusterd only.

As a comparison, I had a look at CentOS rpm: there are *two* init
scripts in there, one for glusterd and one for glusterfsd.

Jan's and Adam's are both good points imho, maybe the use of 2
different init scripts would answer both? And, so, other distros
should follow?
