Im trying to use drbd and kvm and it works ok, but getting a problem I
could figure out yet.

I have 2nodes, kvm, and instaling virtual machines on drdb devices.
The vm create partitions on the drbd devices

My problem is that on the hypervisor this partitions are scaned and after
you cant bring the device up

drbdadm up r0
comes with this error
1: Failure: (104) Can not open backing device.

After I clean the partition links on dmsetup remove xxxx
drbdadm start device ok

I filter drbd backing device on lvm.conf and on lvm level everything ok,
just the partition /dev/mapper gets me in troubles

anyone with the same issue?
what could I do? udev rules? some script to clean partitions?
