Well, it's hard to say, but I am an idiot with big I. Sorry for bothering you with non-existing problem - trouble was not in DRBD but in me. I was executing one command with missing parameter and I haven't noticed it. And this command silently rewrote the partition table on the disk, not drbd. Well, again, I am sorry and I will think four or five times before I write a message to drbd-user list. Luke
