I am having trouble getting rid of an error after creating a new ceph cluster.  The error is: Module 'cephadm' has failed: auth get failed: failed to find client.crash.ceph-0 in keyring retval: -2 Checking the keyrings and disguising the keys: # ceph auth ls ... client.crash.ceph-0.data.igb.illinois.edu         key: keyA         caps: [mgr] profile crash         caps: [mon] profile crash ... mgr.ceph-0.uymvya         key: keyB         caps: [mds] allow *         caps: [mon] profile mgr         caps: [osd] allow * ... Then on the node: # cat mgr.ceph-0.uymvya/keyring [mgr.ceph-0.uymvya]         key = keyB         caps mds = "allow *"         caps mon = "profile mgr"         caps osd = "allow *" So the keys match where they should, but I am thinking that the domain missing off the mgr might be the issue.  This is keeping me from getting rados working since the cluster is showing a health issue.  It looks like this is an issue in my version of ceph (15.2.4)?  Can someone point me to the fix or at minimum tell me how to remove the mgr on ceph-0 from the config so that I can get the system healthy. thanks, Dan
