Hi Bill,

Which steps you ran through on the KVM hosts before trying to add them to the Cluster?

I'm trying to add 3 more nodes to an active cluster. 3 previous nodes are working fine.

I've tried 2 new nodes and they get the same error.

It seems strange to me cause the volume is mounted.

[root@ovirt5n prod vdsm]# df -h|grep rhev

Any ideas welcome.
