[ClusterLabs] Antw: [EXT] Cluster Removing VIP and Not Following Order Constraint

[Strahil Nikolov]

Shouldn't you use kind ' Mandatory' and simetrical TRUE ?
If true, the reverse of the constraint applies for the opposite action (for example, if B starts after A starts, then B stops before A stops).

I'm very sure you just made a configuration mistake.
But nobody can help you unless you show your configuration and example execution of events, plus the expected order of execution.
