Thank you for your knowledge. I have a question. Which pool is affected
when the PG is down, and how can I show it?
When a PG is down, is only one pool affected or are multiple pools
affected?
If only 1 PG is down only 1 pool is affected.
The name of a PG is {pool-num}.{pg-id} and the pools number you find
with "ceph osd lspools".
ceph health detail
will show which PG is down and all other issues.
ceph pg ls
will show you all PG, their status and the OSD they are running on.
