.The Ceph OSD benchmark test might get skipped
Currently, the Ceph OSD benchmark test boot-up might sometimes not run even with `osd_mclock_force_run_benchmark_on_init` parameter set to `true`.
As a consequence, the `osd_mclock_max_capacity_iops_[hdd,ssd]` parameter value is not overridden with the default values.
As a workaround, perform the following steps:
. Set `osd_mclock_force_run_benchmark_on_init` to `true`:
+
.Example
----
[ceph: root@host01 /]# ceph config set osd osd_mclock_force_run_benchmark_on_init true
----
. Remove the value on the respective OSD:
+
.Syntax
[source,subs="verbatim,quotes"]
----
ceph config rm OSD._OSD_ID_ osd_mclock_max_capacity_iops_[hdd,ssd]
----
+
.Example
----
[ceph: root@host01 /]# ceph config rm osd.0 osd_mclock_max_capacity_iops_hdd
----
. Restart the OSD
This results in the `osd_mclock_max_capacity_iops_[ssd,hdd]` parameter being either set with the default value or the new value if it is within the threshold setting.
