David, your correct those were the same device.

Just want to make sure I got this right before another attempt...

When the metadata is created the corresponding /dev/drbd0 resource is
also created and that will replace /dev/vg_cllakvm2/lv_vmstore as what
is mounted to the directory /vmstore ?  So the block device can have
data when it's made into a DRBD resource but not be still mounted as
an active filesystem.  If I'm missing something please correct me.
