Hello. Yesterday I installed drbd for the first time, to see how it works. And almost immediately come across a problem where I don't see an immediate solution.
I followed the howto, built a resource, syncronized it, created a filesystem on it, switched roles (pri/sec) between two hosts, made it primary on two nodes, did some writes etc. So far so good, it all worked just fine. Next, I added "verify-alg sha1;" on both sides and ran `drbdadm adjust' on both nodes. Next I ran 'drbdadm verify'. There was no activity on the resource during this time (between editing and running verify, at least). Now, drbd declared a split-brain situation, and refuses to work. I've no idea where the split-brain come from, since the content should be identical on both sides, and verify should've prove it. I also don't have an idea what to do next, ie, how to resolve the "conflict". Restarting stuff does not help. Since I don't have any data on the volume yet, it's ok to just throw it away. But I'd better learn how to deal with this situation because if it were happened with real data, throwing it away isn't an option ;) And re-creating the resource does not sound right either. Note that I'm a newbie with drbd still... ;) And oh, almost forgot... It's drbd-8.3.3, module built from current git (it says it's 8.3.3rc2), kernel 2.6.31.4-amd64 on both ends, userspace is 32bit. Comments? Thanks! /mjt _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
