>"Split-brain" meaning all but one of the bookies suddenly couldn't connect to the cluster. @devinbost I think we need more Bookie logs for this. Is it possible for you to share some of those? As @eolivelli said, when bookies come up they announce their membership to the cluster via a cookie. If there is a cookie mismatch, it will fail to come up. Hence for this reason, it would be helpful to see the bookie start up logs for that failed bookie. Spinning up a new bookie would help when autorecovery notices underreplicated ledgers and starts copying them to the new bookie to satisfy write quorum ratios. Then again, due to our quorum writes you shouldn't have had any actual data loss I hope. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
