I run a small single-node ceph cluster (the plan was to scale out when I could get more equipment) for home file storage deployed by cephadm. It was running bare-metal, and I attempted a physical-to-virtual migration to a Proxmox VM After doing so, all of my PGs seemed to be "unknown". Initial after a boot, the OSDs appear to be up, but after a while, they go down. I assume some sort of timeout in the OSD start process. The systemd processes (and podman containers) are still running and appear to be happy. I don't see anything that jumps out at me in their logs. I'm relatively new to Ceph, so I don't really know where to go from here. Can anyone provide any guidance? **ceph -s** ``` cluster: id: 768819b0-a83f-11ee-81d6-74563c5bfc7b health: HEALTH_WARN Reduced data availability: 545 pgs inactive 139 pgs not deep-scrubbed in time 17 slow ops, oldest one blocked for 1668 sec, mon.fileserver has slow ops services: mon: 1 daemons, quorum fileserver (age 28m) mgr: fileserver.rgtdvr(active, since 28m), standbys: fileserver.gikddq osd: 17 osds: 5 up (since 116m), 5 in (since 10m) data: pools: 3 pools, 545 pgs objects: 1.97M objects, 7.5 TiB usage: 7.7 TiB used, 1.4 TiB / 9.1 TiB avail pgs: 100.000% pgs unknown 545 unknown ``` **ceph osd df** ``` ID CLASS WEIGHT REWEIGHT SIZE RAW USE DATA OMAP META AVAIL %USE VAR PGS STATUS 0 hdd 1.81940 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 0 down 1 hdd 3.63869 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 0 down 3 hdd 1.81940 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 112 down 4 hdd 1.81940 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 117 down 5 hdd 3.63869 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 0 down 6 hdd 3.63869 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 0 down 7 hdd 1.81940 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 0 down 8 hdd 1.81940 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 106 down 20 hdd 1.81940 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 115 down 21 hdd 1.81940 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 94 down 22 hdd 1.81940 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 98 down 23 hdd 1.81940 0 0 B 0 B 0 B 0 B 0 B 0 B 0 0 109 down 24 hdd 1.81940 1.00000 1.8 TiB 1.6 TiB 1.6 TiB 4 KiB 3.0 GiB 186 GiB 90.00 1.06 117 up 25 hdd 1.81940 1.00000 1.8 TiB 1.6 TiB 1.6 TiB 10 KiB 2.8 GiB 220 GiB 88.18 1.04 114 up 26 hdd 1.81940 1.00000 1.8 TiB 1.5 TiB 1.5 TiB 9 KiB 2.8 GiB 297 GiB 84.07 0.99 109 up 27 hdd 1.81940 1.00000 1.8 TiB 1.4 TiB 1.4 TiB 7 KiB 2.5 GiB 474 GiB 74.58 0.88 98 up 28 hdd 1.81940 1.00000 1.8 TiB 1.6 TiB 1.6 TiB 10 KiB 3.0 GiB 206 GiB 88.93 1.04 115 up TOTAL 9.1 TiB 7.7 TiB 7.7 TiB 42 KiB 14 GiB 1.4 TiB 85.15 MIN/MAX VAR: 0.88/1.06 STDDEV: 5.65 ``` **ceph pg stat** ``` 545 pgs: 545 unknown;
