To clear up a few misconceptions here: * RBD keyrings should use the "profile rbd" permissions, everything else is *wrong* and should be fixed asap * Manually adding the blacklist permission might work but isn't future-proof, fix the keyring instead * The suggestion to mount them elsewhere to fix this only works because "elsewhere" probably has an admin keyring, this is a bad work-around, fix the keyring instead * This is unrelated to openstack and will happen with *any* reasonably configured hypervisor that uses exclusive locking This problem usually happens after upgrading to Luminous without reading the change log. The change log tells you to adjust the keyring permissions accordingly Paul -- Paul Emmerich Looking for help with your Ceph cluster?
