Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Do I have to do something crazy like stack another LVM volume group on top of DRBD, then put a logical volume in that, then clone the VM onto the top of that? So: VM LV VG DRBD LV VG DISK or should it work to have just VM DRBD LV VG DISK as I'm currently attempting, if I just tweak some other aspect here? For clarity, the scheme is to have a 1-to-1 correspondence between each VM and its backing DRBD instance, so that the DRBD primary assignment is atomic, and can be switched per VM between the two hosts.
