It looks this was caused by some commit between these two versions: https://github.com/ceph/ceph/blob/e407049a6a9cb588f27ab270948c404159aa2205/src/tools/rbd/action/DiskUsage.cc#L211 in 10.2.6 upstream version (culprit?): if (!found) { std::cerr << "specified image " << imgname << " is not found." << std::endl; return -ENOENT; } commit: https://github.com/ceph/ceph/commit/ce4c801cfc114f718ca51c32b657fec638ca9aaf#diff-c57e0e173b64b0dd61751c61dcb97a04 It may be caused by other commit, I have _NOT_ tested the 10.2.7-27 without this commit. The issue is still existing in Luminous: [root@mons-0 ~]# ceph version ceph version 12.2.1-39.el7cp (22e26be5a4920c95c43f647b31349484f663e4b9) luminous (stable) [root@mons-0 ~]# rbd du --cluster ceph -p rbd --format=json specified image [root@mons-0 ~]# Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: We have encountered bug, when since RHCS 2.3 version and newer "rbd du --cluster {cluster_name} -p {pool_name} --format=json" on empty pool returns "specified image" output # ceph version # and newer ceph version 10.2.7-27.el7cp (e0d2d4f2fac9d95a26486121257255260bbec8d5) # rbd du --cluster ceph -p rbd --format=json specified image # ceph df GLOBAL: SIZE AVAIL RAW USED %RAW USED 449G 449G 615M 0.13 POOLS: NAME ID USED %USED MAX AVAIL OBJECTS rbd 0 0 0 149G 0 iscsi_vmware 10 115 0 149G 4 The command in RHCS 2.3 version and newer still works fine in case of a pool with image: # rbd du --cluster ceph -p iscsi_vmware --format=json {"images":[{"name":"02iscsi_vmware","provisioned_size":1073741824,"used_size":0}],"total_provisioned_size":1073741824,"total_used_size":0} ------------- This command was working fine in RHCS 2.2 version: # ceph version # and older ceph version 10.2.5-37.el7cp (033f137cde8573cfc5a4662b4ed6a63b8a8d1464) # rbd du --cluster ceph -p rbd --format=json {"images":[],"total_provisioned_size":0,"total_used_size":0} # ceph df GLOBAL: SIZE AVAIL RAW USED %RAW USED 15326M 15227M 102056k 0.65 POOLS: NAME ID USED %USED MAX AVAIL OBJECTS rbd 0 0 0 5075M 0 Version-Release number of selected component (if applicable): 10.2.7-27.el7cp and newer How reproducible: Always Steps to Reproduce: 1. create ceph cluster on version 10.2.7-27.el7cp and newer 2. execute "rbd du --cluster {cluster_name} -p {pool_name} --format=json" on empty pool 3.
