[DRBD-user] drbd raid stays at state peer: Connecting

[G. Milo]

I doubt there's something blocking the resource "hastig" as I assume the
resource was working fine in the past on both nodes? Disabling firewall on
both nodes temporarily would rule out that possibility.Most likely you are
facing some kind of network congestion on the replication network.

Does "drbdadm disconnect hastig" followed by "drbdadm adjust hastig" make a
difference? Otherwise you may need to check the syslog for further clues. I
noticed that you have 4 volumes in that resource. Is there a specific need
to have them configured on one resource rather than creating a separate
resource for each ? I'm not saying it's wrong, it's kind of unusual...
