OSD reporting status

If a Ceph OSD Daemon does not report to a Ceph Monitor, the Ceph Monitor marks the Ceph OSD Daemon down after the mon_osd_report_timeout, which is 900 seconds, elapses. A Ceph OSD Daemon sends a report to a Ceph Monitor when a reportable event such as a failure, a change in placement group stats, a change in up_thru or when it boots within 5 seconds.

You can change the Ceph OSD Daemon minimum report interval by setting the osd_mon_report_interval value at runtime:

Syntax

ceph config set osd osd_mon_report_interval TIME_IN_SECONDS

To get, set, and verify the config you can use the following example:

Example

[ceph: root@host01 /]# ceph config get osd osd_mon_report_interval
5

[ceph: root@host01 /]# ceph config set osd osd_mon_report_interval 
20

[ceph: root@host01 /]# ceph config dump | grep osd
