Node joins/leaves do and should trigger new transitions, but that should not result in any actions if the node is in standby. The cluster will wait for any actions in progress (such as a live migration) to complete before beginning a new transition, so there is likely something else going on that is affecting the migration. > Logs and more details, please! Particularly the detail log on the DC should be helpful. It will have "pengine:" messages with "saving inputs" at each transition. > > > > Best regards, > > Jozsef > > ‑‑ > > E‑mail : kadlecsik.joz...@wigner.mta.hu > > PGP key: http://www.kfki.hu/~kadlec/pgp_public_key.txt > > Address: Wigner Research Centre for Physics, Hungarian Academy of > > Sciences > > H‑1525 Budapest 114, POB. 49, Hungary > > _______________________________________________ > > Users mailing list: Users@clusterlabs.org > > https://lists.clusterlabs.org/mailman/listinfo/users > > > > Project Home: http://www.clusterlabs.org > > Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratc > > h.pdf > > Bugs: http://bugs.clusterlabs.org > > > > _______________________________________________ > Users mailing list: Users@clusterlabs.org > https://lists.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 -- Ken Gaillot <kgail...@redhat.com> _______________________________________________ Users mailing list: Users@clusterlabs.org https://lists.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
