Hello!

In some situations such as split-brain it is hard to predict syncronization
order of DRBD. So is it possible to ask DRBD to test whether it will be
SyncTarget or SyncSource? Or is it possible to specify synchronization order
without invalidating the whole device?

It will helps to recover after split-brains, so more actual data will not be
lost and total synchronization of 1.2 TB disk array will be avoided.

If it not already possible, I think it will be two very useful features of
cluster management:
1) Probing a synchronization order without starting the synchronization.
2) Explicit chosing the synchronization order without total invalidation,
   so sychronization can be quick.

Thanks.
