There's no way for one node to predict that all other nodes will also be unable to see the target. The only workarounds I see are: * Use a second ping target on a different path, if available * If the maintenance is planned, you could disable the relevant constraints during the window > > Thanks for any help ! > > Best regards, > Detlef _______________________________________________ Users mailing list: Users@clusterlabs.org http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
