query for individual pg, its unable to find it :( -------------------------------- *# ceph pg 1.1 queryError ENOENT: i don't have pgid 1.1* *# ceph pg 18.1a queryError ENOENT: i don't have pgid 18.1a* *# ceph pg 18.1b queryError ENOENT: i don't have pgid 18.1b* -------------------------------- As per https://docs.ceph.com/docs/master/rados/operations/pg-states/, --------------------------------- *unknown : *The ceph-mgr hasn’t yet received any information about the PG’s state from an OSD since mgr started up. --------------------------------- I confirmed that all ceph osds are up, and the ceph-mgr service is as well running. Is there anything else that I need to check to rectify the issue? -- Regards, Soumya
