Hello, before I ran the update to 14.2.8 I checked that the state was healthy with all OSDs up and in. I still have the command history I typed visible in my kde terminal buffer and there I see that after the update but before the reboot I ran a ceph -s and there were 144 osd's up and in the state was HEALTH_OK. Could it be of interest that the node rebooted was a monitor node and should mon_osd_down_out_interval at least in theory have prevented what happened to my cluster? Thanks Rainer Am 05.03.20 um 09:49 schrieb Dan van der Ster:
Did you have `144 total, 144 up, 144 in` also before the upgrade? If an osd was out, then you upgraded/restarted and it went back in, it would trigger data movement. (I usually set noin before an upgrade).

I found some information in ceph.log that might help to find out what happened. node2 was the one I rebooted:

Hello,
at the moment my ceph is still working but in a degraded state after I upgraded one (in 9) hosts from 14.2.7 to 14.2.8 and rebooting this host (node2, one monitor in 3) after the upgrade.
Usually before rebooting I set
ceph osd set noout ceph osd set nobackfill ceph osd set norecover
before rebooting, but I fogot this time. After having realized my error I thought, ok I forgot to set the flags but I configured mon_osd_down_out_interval to 900sec:
# ceph config get mon.mon_osd_down_out_interval WHO MASK LEVEL OPTION VALUE RO mon advanced mon_osd_down_out_interval 900
The reboot took 5min so I expected nothing to happen. But it did and now I do not understand why and if there are more timeout values I could/should set to avoid this happening again if I ever should again forget to set the noout , nobackfill, norecover flags prior to a reboot?
