I'm seeing an error from the rbd map command running in ceph-container;
I had initially deployed this cluster as Luminous, but a pull of the
ceph/daemon container unexpectedly upgraded me to Mimic 13.2.1.
[root@nodeA2 ~]# ceph version
ceph version 13.2.1 (5533ecdc0fda920179d7ad84e0aa65a127b20d77) mimic
(stable)
[root@nodeA2 ~]# rbd info mysqlTB

[root@nodeA2 ~]# rbd map mysqlTB
rbd: failed to add secret 'client.admin' to kernel
In some cases useful info is found in syslog - try "dmesg | tail".
rbd: map failed: (1) Operation not permitted
[root@nodeA2 ~]# type rbd
rbd is a function
rbd ()
{
sudo docker exec ceph-mon-nodeA2 rbd --cluster ceph ${@}
}
[root@nodeA2 ~]# ls -alF /etc/ceph/ceph.client.admin.keyring
-rw------- 1 ceph ceph 159 May 21 09:27 /etc/ceph/ceph.client.admin.keyring
System is CentOS 7 with the elrepo mainline kernel:
[root@nodeA2 ~]# uname -a
Linux nodeA2 4.18.3-1.el7.elrepo.x86_64 #1 SMP Sat Aug 18 09:30:18 EDT

I see a similar question here with no answer:

dmesg shows nothing related:
