Hi,

Is it possible to have more infos or announce about this problem ?

I'm currently waiting to migrate from luminious to mimic, (I need new quota feature for cephfs)

is it safe to upgrade to 13.2.2 ?  

or better to wait to 13.2.3 ? or install 13.2.1 for now ?

This issue is being tracked here: http://tracker.ceph.com/issues/36346 

The problem was caused by a backport of the wrong commit which 
unfortunately was not caught. The backport was not done to Luminous; 
only Mimic 13.2.2 is affected. New deployments on 13.2.2 are also 
affected but do not require immediate action. A procedure for handling 
upgrades of fresh deployments from 13.2.2 to 13.2.3 will be included 
in the release notes for 13.2.3.
