I'm setting a peacemaker cluster with DRBD active/passive. Everything
works as expected (starting/stopping /migrating DRBD resources),
however if I put any node in standby all the DRBD resources age going
to "Unmanaged" mode. As I understand form log files, stopping of DRBD
resource on the standby node fails for some reason (still don't have
any clue why) after that, obviously, cluster says "Preventing
ms_drbd_resourcename from re-starting anywhere in the cluster". For
setting the cluster I used the documentation on DRBD site. I'd
appreciate any help. The corresponding snips form configuration are
below.
Tanks everybody in advance,
Vlad.
