[ceph-users] Re: All monitors fall down simultaneously when I try to map rbd on client

yes, this is a bug, indeed. https://www.spinics.net/lists/ceph-users/msg82468.html

Remove mappings by: $ `ceph osd dump` For each pg_upmap_primary entry in the above output: $ `ceph osd rm-pg-upmap-primary <pgid>`
