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

i am confuse a bit in recovery on split-brain situation with DRBD.
because there are two contradicting statement which i can not
understand therefore i need some help to understand the scenario.

at the end of the section "Recovery from split brain when using two
DRBD volume" there is written "
In most cases the recovery will take a few minutes since DRBD only
needs to copy the data that has changed since the split-brain

this is quite contradicting the statement written in "Recovery from
communication failure" which says that

"In this case it will be necessary to discard the data of one of the
nodes. Normally one would choose to discard the data of the
least-active node."

 so on one side it is written that we need to delete the whole data
and re-sync  and on the other hand it is written that the process will
take few minutes (probably) because most of the time DRBD updates only
the changes that have been made since splint brain.

anyone please help.
