After collecting all of the information in my previous mailing, I then tried restarting the service using clusvcadm -R, to no avail: | $ sudo clusvcadm -R dn | Local machine trying to restart service:dn... And so it stood for over a minute, with no evidence that it was actually trying to start anything, so I hit ^C. Next, I restarted rgmanager on all three nodes simultaneously, using "sudo service rgmanager restart". When rgmanager came back up, the service was in status "recoverable" and then soon after, it got started successully on node2. So now the service is running, but it's still a complete mystery to me why it never got restarted before, and why I had to restart rgmanager to get it to bring the service up. I also don't know what, if anything, I need to do to prevent this from happening again. [I did try killing processes a few times and observed successful relocations and restarts, so the cluster seems to be in a good state for now...] -- Cos -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
