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@xxxxxxxxx> 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.
