[PVE-User] DRBD confusion in PVE wikki docs.

[Muhammad Yousuf Khan]

here is the proxmox official wikki doc.
http://pve.proxmox.com/wiki/DRBD

i agree with Robert, what document saying is ,
it suggest us to create two volume r0 and r1
on node1 we use r0
and on node2 use r1

if split brain occurred then we dont have to shift whole data we just
discard the old data from victim node and resync the drbd data.

for instance in my confusion case if we discard the data from node1 r1
and node2 r0
in case of split brain. so the concept of saying it will take few
minutes as it updates only the changes, doesn't fit in the scenario
and making me confuse.

if you please explain i'll be very thankful.
