Ceph

the ceph warn is
22 pgs degrade 24 undersized.

do the command "ceph health detail" to show the unhealth pgs

and do the command ceph pg pair PGid ,but no available, the warn still exist
and do the command ceph pg deep-scrub PGID , no available, then warn still exist
and do the command ceph osd-create-pg pgid --yes-i-really-mean-it no available, the warn still exist

and do the command ceph pg PGID query ,
I find all the PGS‘s copy(1/3),one is in the same host.
and i debug the osd'slogs I also find when i do the command above (eph pg pair PGid,ceph pg deep-scrub PGID,ceph osd-create-pg pgid etc), the main osd's log can not get it these command ,( but normal pgs can get the logs).

I am lost, my comany bussine are in the ceph cluster. so I want to ge help from ceph experts ,I am very sorry.
