Hi. OK. We've now tried that. We're on openSUSE 13.1. With the stock 2.3
ctdb:
Nothing is started.

With 2.5.3 from the ha repo indeed, smb starts, but both nodes are
reported as UNHEALTHY. Always.

We have drbd primary:primary and want both nodes live and running smbd.
If one goes down, we still have the other.
Qn. Is this possible?
Cheers,
Steve
