I understand this is not directly oVirt/RHEV related, but I really don't get why this ctdb cluster has worked for months, and stopped recently (I'll have to deeply dig into the release notes of the upgraded packages and try to find something useful).
I post that here to : - ask if some of you are also running clusters amongst VMs (not particularly amongst datacenters - VM discussion amongst hosts may also be an issue) - leave a trace in case that may help debug some setups
Still archiving for future googlers : I was not very found of modifying every hypervisors in my oVirt datacenters, so I finally switched my cman's cluster.conf into "transport=updu" and it did the trick. I guess in a two-nodes cluster, this has no downside. In a hundred nodes one, things could be different. -- Nicolas Ecarnot
