mgr down : OSDMap.cc: 5155: FAILED ceph_assert(osd_weight.count(oid)

24 Aug 2023

      When ceph osd reweight <osd> 0 is executed, mgrs go down and after several retries, mgrs eventually go down.
In mgr.log and crashinfo, the following logs are displayed.

BUILD/ceph-17.2.3/src/osd/OSDMap.cc: 5155: FAILED ceph_assert(osd_weight.count(oid))

There seems to be a problem with the ceph_assert(osd_weight.count(oid)) part.
Anyone helps me.
