Description

(Opening with increased priority since this appears to be a regression)

With a recent master, ceph-mgr --help stopped working. Instead of a help message, it displays:

# ceph-mgr --help
failed to fetch mon config (--no-mon-config to skip)

Also, not just ceph-mgr --help, but also trying to start the ceph-mgr process fails with the same error message.

Ricardo Dias found a workaround:

[mgr]
keyring = /var/lib/ceph/mgr/ceph-target137074025108/keyring

With this in ceph.conf, it becomes possible to start the ceph-mgr process with --no-mon-config

(NOTE: this is a Python 3 system; no Python 2 installed.)

An earlier build of master - 820dac980e9416fe05998d50cac633c81a87b9e3, v13.0.1-3181-g820dac980e - did not exhibit this problem in the same environment: that's why I believe it is a regression.
