The cephadm.log should show some details why it fails to deploy the daemon. If there's not much, look into the daemon logs as well (cephadm logs --name prometheus.ceph02.mousetech.com). Could it be that there's a non-cephadm prometheus already listening on port 9095?

Zitat von Tim Holloway <t...@mousetech.com>:

I finally got brave and migrated from Pacific to Reef, did some banging and hammering and for the first time in a long time got a complete "HEALTH OK" status.

However, the dashboard is still not happy. It cannot contact the Prometheus API on port 9095.

I have redeployed Prometheus multiple times without result.

I'm pretty sure that at one time there were no less than 3 different Prometheus containers running on one of the configured Prometheus servers, but now all I can get is the node-exporter.

Worse, if I do:

ceph orch reconfig prometheus

I get:

Error EINVAL: No daemons exist under service name "prometheus". View currently running services using "ceph orch ls"

But if I do:

ceph orch ls

I get:

prometheus                         ?:9095           0/1 -          116s  ceph02.mousetech.com

Suggestions?
