Hi,
With 3 replicas, a pg hs 3 osds. If all those 3 osds are down, the pg becomes unknow. Is that right?
Yes. As no OSD can report the status to the MONs.
If those 3 osds are replaced and in and on, is that pg going to be eventually back to active? Or anything else has to be done to fix it?
If you can bring back the OSDs without wiping them: Yes As you mention the word 'replaced' I was wondering what you mean by that. If you replace the disks without data recovery the PGs will be lost. So you need to bring back the OSDs with their data in tact for the PG to come back online. Wido
