Hi, I'm a new member to the linux-cluster mailing list. I'm trying to set up a 2-node cluster using RedHat Cluster based on OpenAIS, with manual fencing (for now). When I reboot a node (l6-z-5), I get the following error messages in /var/log/syslog of the other node (l6-z-12): Oct 12 16:38:02 l6-z-12 fenced[4508]: fencing node "l6-z-5" Oct 12 16:38:02 l6-z-12 fenced[4508]: fence "l6-z-5" failed Probably because of that fencing failure, the service located on l6-z-5 doesn't failover to l6-z-12. The fenced error messages repeat until l6-z-5 rejoins the cluster. Does anyone know what's going on? My cluster.conf includes this for the fencing part: <fencedevices> <fencedevice agent="fencemanual" name="last_resort"/> </fencedevices> My distro is Ubuntu Edgy, which has packages for RedHat Cluster and OpenAIS. The version of cman seems to be 2.20061002, and the version of openais 0.80.1.
