Hi,

i'm currently a bit confused. I have several resources running as VirtualDomains, the vm reside on plain logical volumes without fs, these lv's reside themself on a FC SAN. 
In that scenario i need cLVM to distribute the lvm metadata between the nodes.
For playing around a bit and getting used to it i created a DRBD partition. It resides on a logical volume (one on each node), which should be possible following the documentation on linbit.
The lv's reside each on a node on the local storage, not on the SAN (which would be a very strange configuration).
But nevertheless it's a cLVM configuration. I don't think it's possible to have a cLVM and non-cLVM configuration at the same time on the same node.
Is that possible what i try to do ?


Bernd
