Update on "ceph-s". A machine was in the process of crashing when I took the original snapshot. Here it is after the reboot: [root@dell02 ~]# ceph -s cluster: id: 278fcd86-0861-11ee-a7df-9c5c8e86cf8f health: HEALTH_WARN 1 filesystem is degraded 25 client(s) laggy due to laggy OSDs services: mon: 3 daemons, quorum dell02,www7,ceph03 (age 8m) mgr: ceph08.tlocfi(active, since 81m), standbys: www7.rxagfn, dell02.odtbqw mds: 1/1 daemons up, 2 standby osd: 7 osds: 7 up (since 12h), 7 in (since 19h); 308 remapped pgs rgw: 2 daemons active (2 hosts, 1 zones) data: volumes: 0/1 healthy, 1 recovering pools: 22 pools, 681 pgs objects: 125.10k objects, 36 GiB usage: 91 GiB used, 759 GiB / 850 GiB avail pgs: 47772/369076 objects misplaced (12.944%) 373 active+clean 308 active+clean+remapped io: client: 170 B/s rd, 0 op/s rd, 0 op/s wr On Sat, 2024-07-27 at 11:31 -0400, Tim Holloway wrote:
I was in the middle of tuning my OSDs when lightning blew me off the Internet. Had to wait 5 days for my ISP to send a tech and replace a fried cable. In the mean time, among other things. I had some serious time drift between servers thanks to the OS upgrades replacing NTP with chrony and me not having thought to re-establish a master in-house timeserver.
Ceph tried really hard to keep up with all that, but eventually it was just too much. Now I've got an offline filesystem and apparently it's stuck trying to get back online again.
