Heya, I had a question about what behavior to expect from a particular scenario. Given: A. Unclean leader elections are disabled B. A partition is led by Broker1 and followed by Broker2 C. Broker1 is on offset 100 D. Broker2 is on offset 90 E. Broker2 has fallen out of the ISR, leaving only Broker1 in the ISR F. Broker1 has a hard drive failure and goes down. All messages for the partition in question are permanently lost.
_As I understand it_, the only way for the partition to come back online is to bring Broker1 back online, and suffer the loss of 100 messages (as Broker2's log will be truncated to Broker1's offset, which will start from scratch due to the hard drive loss) Is there a procedure in such a case, to force-elect Broker2 the leader, and thus only lose 10 messages? Thanks! - Jordan Pilat
