Subject: Re: [pve-devel] corosync bug: cluster break after 1 node clean shutdown

Yes, but at shutdown, it could be great to stop pmxcfs before corosync ?
I ask the question, because the 2 times I have problem, it was when shutting down a server.
So maybe some strange behaviour occur with both corosync && pmxcfs are stopped at same time ?


looking at the pve-cluster unit file,
why do we have "Before=corosync.service" and not "After=corosync.service" ?

I have tried to change this, but even with that, both are still shutting down in parallel.

the only way I have found to have clean shutdown, is "Requires=corosync.server" + "After=corosync.service".
But that mean than if you restart corosync, it's restart pmxcfs too first.

I have looked at systemd doc, After= should be enough (as at shutdown it's doing the reverse order),
but I don't known why corosync don't wait than pve-cluster ???


(Also, I think than pmxcfs is also stopping after syslog, because I never see the pmxcfs "teardown filesystem" logs at shutdown)

This is by intention - we do not want to stop pmxcfs only because coorosync service stops.
