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.

2) Use the drbd-user list for that kind of questions.
