On any node that is already in the cluster... I always use the first

In that case it is exactly as drbdmanage told you:

CAUTION! Note that:
* Any previous drbdmanage cluster information may be removed
* Any remaining resources managed by a previous drbdmanage installation
that still exist on this system will no longer be managed by drbdmanage

The control volume gets overwritten, the old information is lost.

1) Don't TO/CC me, I'm on the list.
2) Use the drbd-user list for that kind of questions.
