Thank you for your reply.
Now I want to try to add another lvm vg for the storage, but how to do?
I think i would overwrite the existing config when doing the following, do

volume-group = storagepool # or the value of drbdctrl-vg if it is set and
volume-group is unset
lvm-path = /sbin
dev-path = /dev/

Or is this then an additional entry next to drbdpool?

Best Regards,
