Hi all,

on a mimic 13.2.8 cluster I have set

  mon                      advanced mon_osd_down_out_subtree_limit    host

According to the documentation:

=======================
mon osd down out subtree limit

Description

    The smallest CRUSH unit type that Ceph will not automatically mark out. For 
instance, if set to host and if all OSDs of a host are down, Ceph will not 
automatically mark out these OSDs.
=======================

if I shut down all OSDs on this host, these OSDs should not be marked out 
automatically after mon_osd_down_out_interval(=600) seconds. I did a test today 
and, unfortunately, the OSDs do get marked as out. Ceph status was showing 1 
host down as expected.

Am I doing something wrong or misreading the documentation?

Thanks!
