Protocol is indeed irrelevant to the error: we reproduced the problem while protocol was 'C'. Today, we ran this test: filesystem was mounted on /dev/md3 (without drbd), and we generated high traffic on the network interface (by running netcat from /dev/zero on one host to /dev/null on another). There where NO filesystem errors. We are planning to run a test when the filesystem is mounted from drbd, and the gigabit interface is completely idle. When we do that, we'll know for sure, but so far it *seems* that there is no relation between the appearance of errors and network activity. Another test that we ran: we waited until a filesystem error on drbd device appeared, did *not* run fsck, removed drbd module and mounted the filesystem from md device. It works for almost 24 hours now, there are no errors! Apparently, the filesystem errors indeed appear only in the in-memory copy only. I figure that this is an important symptom to narrow down the search. I'll come back when we have more information.
