Description

See thread "[ceph-users] failed to open snapshot after 'rados cppool '" at e.g. http://www.spinics.net/lists/ceph-users/msg07357.html

After doing that cppool, an attempt to delete no-longer-existing rbd snapshots crashes the monitor with

osd/osd_types.cc: 799: FAILED assert(is_unmanaged_snaps_mode())

 ceph version 0.72.2 (a913ded2ff138aefb8cb84d347d72164099cfd60)
