I think this should be considered a bug
If you have a server crash, glusterfsd process obviously doesn't exit properly and thus this could least to IO stop ?
And server crashes are the main reason to use a redundant filesystem like gluster

This is exactly the problem,Systemctl stop glusterd does *not* kill the brick processes.On CentOS with gluster 3.10.x there is also a service, meant to only stop glusterfsd (brick processes). I think the reboot process may not be properly stopping glusterfsd or network or firewall may be stopped before glusterfsd and so the nodes go into the long timeout.Once again , in my case a simple reboot hangs my VMs, whereas stopping glusterd *and* glusterfsd processes, then reboot works perfectly.DiegoOn Sep 8, 2017 6:36 AM, "Pavel Szalbot" <pavel.szalbot@xxxxxxxxx> wrote:Hi Diego,
indeed glusterfsd processes are runnin and it is the reason I do
server reboot instead of systemctl glusterd stop. Is killall different
from reboot in a way glusterfsd processes are terminated in CentOS
(init 1?)?
However I will try this and let you know.
