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

Hi,
I have done a new test, this time with "systemctl stop corosync", wait 15s, "systemctl start corosync", wait 15s.
I was able to reproduce it at corosync stop on node1, 1second later /etc/pve was locked on all other nodes.
I have started corosync 10min later on node1, and /etc/pve has become writeable again on all nodes
node1: corosync stop: 01:26:50
node2 : /etc/pve locked : 01:26:51

pmxcfs: coredump :http://odisoweb1.odiso.net/core.17995.gz
node1:corosync start: 01:35:36
http://odisoweb1.odiso.net/corosync-start.log
BTW, I have been contacted in pm on the forum by a user following this mailing thread,
and he had exactly the same problem with a 7 nodes cluster recently.
(shutting down 1 node, /etc/pve was locked until the node was restarted)

thanks, I'm now using this specific one, had a similar (but all nodes writes)
running here since ~ two hours without luck yet, lets see how this behaves.
