Hi Kristoffer, ok I see, but why maintain both? Let a coin decide which one, but I think its not very helpful to maintain both. best regards Stefan > Gesendet: Mittwoch, 27.

OK I see, but it would be good if somebody mark one of this as deprecated and then delete it. So that noone get confused about these. best regards Stefan > Gesendet: Dienstag, 26.

At one time, there were two different open-source clustering environments, each with its own set of fence agents. The community eventually settled on Pacemaker as a sort of merged evolution of the earlier environments, and so it supports both styles of fence agents. Thus, you often see an "external/*" agent and a "fence_*" agent available for the same physical device. However, they are completely different implementations, so there may be substantive differences as well. I'm not familiar enough with these two to address that, maybe someone else can. -- Ken Gaillot ___ 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

As I understand it, external/ipmi is deprecated and fence_X are the agents that should be used now. -- Digimer Papers and Projects: https://alteeve.com/w/ "I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops." - Stephen Jay Gould ___ 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
[ClusterLabs] difference between external/ipmi and fence_ipmilan
Hello, can somebody tell me the difference between external/ipmi and fence_ipmilan? Are there preferences? Is one of these more common or has some advantages?
