I downloaded LCMC 1.0.2 to try it out. Pointed it to my existing
DRBD/Corosync/Pacemaker cluster and had it retrieve all the details and then
it crashed with a null pointer exception. If I fire it up now, it has
remembered the details of the cluster and asks for my ssh passphrase to
connect to both machines, asks for my sudo password for both nodes, pulls a
bunch of info, paints some icons then crashes with
AppError.Text
release: 1.0.2
java: Sun Microsystems Inc. 1.6.0_26
uncaught exception
java.lang.NullPointerException
null

Hi,

it could be that there are some colocation or order constraints, that
don't point to any resource and LCMC doesn't handle it right. Can you
send your Pacemaker config?
