Hi,
it would be nice if stonith-resources that only shoot one node automatically
set the anti-location constraint. But I fear you gotta do this by hand.
While an ipmi-stonith killing itself will work in that the machine dies, it
can't report back to pacemaker and then afair pacemaker hangs and

Hi,
I went with running lsb:libvirt in the cluster too. That way you can define
dependencies. And when corosync isn't started automatically (like when you do
maintainance without switching init-levels) libvirt is stopped too.
Have fun,

This is what we did (spoiler: no pacemaker)
We connect the openvpn-hosts via tinc (could also be openvpn but tinc is
more flexible when servers both initiate the connection) and put these
tunnels into a bridge (with stp).
Then all these nodes have openvpn with server-certificates from the same

Unfortunately that didn't help. But changing "use_logd: yes" to "use_logd: no"
made all the output appear in /var/log/corosync/corosync.log..
