I have a 3 node ceph cluster in my home lab. One of the pools spans 3 hdds, one on each node, and has size 2, min size 1. One of my nodes is currently down, and I have 160 pgs in 'unknown' state. The other 2 hosts are up and the cluster has quorum. Example `ceph health detail` output: pg 9.0 is stuck inactive for 25h, current state unknown, last acting [] I have 3 questions: Why would the pgs be in an unknown state? I would like to recover the cluster without recovering the failed node, primarily so that I know I can. Is that possible? The boot nvme of the host has failed, so I will most likely rebuild it. I'm running rook, and I will most likely delete the old node and create a new one with the same name. AFAIK, the OSDs are fine. When rook rediscovers the OSDs, will it add them back with data intact? If not, is there any way I can make it so it will?
