5 so namespaces won't work for me at the moment. Could you please explain what the magic behind "class rbd metadata_list" is? Is it thought to "simply" allow access to the basepool (rbd in my case), so I authorize access to the pool instead of a namespaces? And if th

[ceph-users] ceph -s finds 4 pools but ceph osd lspools says no pool which is the expected answer

ght afterwards. In this case the pool is created and ceph -s shows one pool more (5) and if delete this pool again the counter in ceph -s goes back to 4 again. How can I fix the system so that ceph -s also understands that are actually no pools? There must be some inconsistency. Any ideas? Thanks R
