[Pacemaker] failure handling on a cloned resource

[Johan Huysmans]

Hi All,

I've created a bug for this issue i'm having
http://bugs.clusterlabs.org/show_bug.cgi?id=5154

I think this is a bug due to the fact that it worked on older releases.

Can someone verify it really is a bug, or just a configuration mistake.

Thanks!

Greetings,
Johan Huysmans
