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?
Thanks if anyone can explain to me what might have happened....
Rainer
