Hi to all
i would like to spin up a new shared storage
should i use drbd 8 or 9?

Additionally and more important: are there any ways to totally avoid
splitbrains? Obviously, the network used for sync is fully redundant (at
least 2 or 3 bonded interfaces)

Is this enough?
if i understood properly, split brain happens when the two nodes loose
their interconnection,  thus each node will detect itself as the online
node and start to write.
when writes differs between nodes, i have a split brain

But if the sync network is redundant, no splitbrain should occur

Anything else to be aware of?
