Why is the warning 'failed to probe daemons or devices' showing up after upgrading Ceph from Red Hat Ceph Storage 5.0 to 5.1?
Issue
-
After upgrading Red Hat Ceph Storage ( RHCS ) from version 5.0x to version 5.1, the following warning shows in the
ceph health detail
output:[root@node01 ~]# ceph health detail HEALTH_WARN failed to probe daemons or devices [WRN] CEPHADM_REFRESH_FAILED: failed to probe daemons or devices host node01 `cephadm ceph-volume` failed: cephadm exited with an error code: 1, stderr:Inferring config /var/lib/ceph/<fsid>/mon.node01/config ERROR: [Errno 2] No such file or directory: '/var/lib/ceph/<fsid>/mon.node01/config'
The above error points to a non existing directory
/var/lib/ceph/<fsid>/mon.node01/config
. This directory holds the configuration files for a Ceph mon service, but oddly, the nodenode01
is not a monitor. -
Why is this message showing in a node that is not a monitor?

How to eliminate this warning?
Environment
