Hi there, We are trying to upgrade a cluster in our test environment to Nautilus, and we ran into this hurdle after upgrading Mons and Mgrs. Restarting the first OSD, we noticed that ceph -s is reporting many PG's state as unknown:
[root@cephosd0041 ceph]# ceph pg stat 996 pgs: 263 active+clean, 733 unknown; 71 GiB data, 364 GiB used, 11 TiB / 11 TiB avail; 340 B/s rd, 3.0 KiB/s wr, 36 op/s As far I can research this is basically MGR's reporting that it didn't receive information from OSD's, what can we do to resolve this? or is this just a red herring by any chance? Thank you, -- Eric Choi Senior Software Engineer 2 | Core Platform
