Hi Eugen, this is the output: ceph mgr module ls
{
"always_on_modules": [
"balancer",
"crash",
"devicehealth",
"orchestrator",
"pg_autoscaler",
"progress",
"rbd_support",
"status",
"telemetry",
"volumes"
],
"enabled_modules": [
"cephadm",
"dashboard",
"diskprediction_local",
"iostat",
"prometheus",
"restful"
],
"disabled_modules": [
...
}
As you see balancer/crash/… are in section always_on. I checked it on all of the 3 monitor nodes with the same output.
Then, checking disabled_modules I’ve seen many modules that could help to track some more information (logs) on our problem, like:
- alerts
- insights
- test_orchestrator
- and other…
But we are not sure if we can enable some of them. Now all the logs we have from Ceph are not showing errors. Would it help to see more logs to enable some of those modules?
On the other hand, as for what you indicate us of the commands that hang, we see that the containers that launch it remain executing, since they are waiting to finish. So you can see here the list of tests that remain running (hung):

So the containers will have to be eliminated.
As for the logs of these containers nothing appears inside the container (docker logs xxxx), only, when you kill it you can see (--verbose):
[ceph: root@spsrc-mon-1 /]# ceph —verbose pg stat
….
validate_command: pg stat
better match: 2.5 > 0: pg stat
bestcmds_sorted:
[{'flags': 8,

'sig': [argdesc(<class 'ceph_argparse.CephPrefix'>, req=True, name=prefix, n=1, numseen=0, prefix=pg),
argdesc(<class 'ceph_argparse.CephPrefix'>, req=True, name=prefix, n=1, numseen=0, prefix=stat)]}]
Submitting command: {'prefix': 'pg stat', 'target': ('mon-mgr', '')}
submit ['{"prefix": "pg stat", "target": ["mon-mgr", ""]}'] to mon-mgr
[hung forever …]
Kind regards,
Manu.
