Ceph configuration: mon_osd_down_out_interval

[some-admins]

How do I change the Ceph configuration of a running cluster?

I edited /etc/pve/ceph.conf

[mon]
         mon_osd_adjust_down_out_interval = false
         mon_osd_down_out_interval = 10

Even after rebooting the node, I still get:

root@px01:~# ceph --admin-daemon /var/run/ceph/ceph-osd.0.asok config show | grep down_out_interval
    "mon_osd_adjust_down_out_interval": "true",
    "mon_osd_down_out_interval": "600"

All MONs need to have the same truth. And then it depends, if the config can be changed on a running service.

See Ceph docs on how to change the running config.
