lvm on top of drbd

[tobias]

Hi,

does anybody know how EXACTLY it works when we have lvm LV's on top of the drbd ...
I mean both nodes need to be aware of changes in order not to loose data when they are both primary/primary

is the pve-manager just starting a vgscan on both nodes or what?

or is clvm used?

thx

did you get this: http://pve.proxmox.com/wiki/DRBD

clvm is not used, we use our own locking.
