[DRBD-user] Data consistency question

I have a question regarding filesystem consistency - say I choose async protocol (A) and the master peer node crashes fatally in the middle of write operation.
The slave peer node will then be outdated, but what happens to the filesystem on the top of the replicated block device - will I be able to restore data from the outdated peer?
My understanding is that DRBD completely ignores the filesystem, so unless I choose synchronous replication protocol C, filesystem corruption can occur on the peer node.
Am I right?
