Hello,
I'm still building a xen cluster managed by pacemaker/openais.
Things are quite close to be OK I think, execpt when I want to put a
node in standby mode:
When it happens, all XEN VM are shut down and restarted on the other node.
When I ask for ressource migration, XEN Live Migration does the job so
that no downtime occurs.
Is there any way to "slow down" standby mode so that XEN VM can migrate
gracefully ?
Bellow you can find my cluster configuration, if it can help.
Thanks,
JB
