Hi
I'm currently fiddling with a cluster of xen domains on different
physical machines.
Physical Machine 1 runs virtual Machine A
Physical Machine 2 runs virtual Machine B
A and B are my HA nodes.
I modified the xen-stonith plugin from [1] to work with 2 dom0 hosts and
configured stonith to use this plugin. It works great.
One thing this can not accomplish is a node reboot if dom0 loses all
network connections (3, so I have some redundancy here). Total loss of
network connectivity (in dom0 !!) causes splitbrain.
I think suicide might help here. It should be done in the node if no
ping hosts are available.
So here are my questions:
Can I configure multiple stonith devices (extern/xen and suicide) at a time?
Could someone share some cib.xml snippet that says "if no ping hosts are
reachable, commit suicide"?
Regards
Dominik
