Description

If I try to map rbd from a cluster where osd numbering is discontinuous it fails with message [85115.711643] libceph: corrupt full osdmap (-2) epoch 248869 off 10063. The cluster runs nautilus 14.2.18 on RHEL 7. The ceph-common package on client is also nautilus and the OS is RHEL 8. The mapping succeeds from clients running RHEL 7. I tried with mimic, nautilus and octopus ceph-client packages.

The dmesg output with kernel debugs enabled from client was too large to be attached. It can be downloaded from here
