Eeek! Don't run `osd_find_best_info_ignore_history_les = true` -- that leads to data loss even such that you don't expect. Are you sure all OSDs are up? Query a PG to find out why it is unknown: `ceph pg <id> query`. Feel free to share that In fact, the 'unknown' state means the MGR doesn't know the state of the PG -- is your MGR running correctly now? -- Dan On Fri, Feb 5, 2021 at 4:49 PM Jeremy Austin <jhaustin@gmail.com> wrote:
I was in the middle of a rebalance on a small test cluster with about 1% of pgs degraded, and shut the cluster entirely down for maintenance.
On startup, many pgs are entirely unknown, and most stale. In fact most pgs can't be queried! No mon failures. Would osd logs tell me why pgs aren't even moving to an inactive state?
I'm not concerned about data loss due to the shutdown (all activity to the cluster had been stopped), so should I be setting some or all OSDs " osd_find_best_info_ignore_history_les = true"?
Thank you,
