Ah, after researching some more I think I got hit by this bug:
https://github.com/ceph/ceph/pull/25585
At least that's exactly what I see in the logs: "Interpreter change
detected - this module can only be loaded into one interpreter per process."
Ceph modules don't seem to work at all with the newest Ubuntu version.
Only one module can be loaded. Sad :-(
Hope this will be fixed soon...

Hi my beloved Ceph list,
After an upgrade from Ubuntu Cosmic to Ubuntu Disco (and according
Ceph packages updated from 13.2.2 to 13.2.4), I now get this when I
enter "ceph health":
HEALTH_WARN 3 modules have failed dependencies
"ceph mgr module ls" only reports those 3 modules enabled:
"enabled_modules": [
"dashboard",
"restful",
"status"
],
...
Then I found this page here:
docs.ceph.com/docs/master/rados/operations/health-checks
Under "MGR_MODULE_DEPENDENCY" it says:
"An enabled manager module is failing its dependency check. This
health check should come with an explanatory message from the module
about the problem."
What is "this health check"? If the page talks about "ceph health" or
"ceph -s" then, no, there is no explanatory message there on what's wrong.
Furthermore, it says:
"This health check is only applied to enabled modules. If a module is
not enabled, you can see whether it is reporting dependency issues in
the output of ceph module ls."
The command "ceph module ls", however, doesn't exist. If "ceph mgr
module ls" is really meant, then I get this:
{
"enabled_modules": [
"dashboard",
"restful",
"status"
],
"disabled_modules": [
{
"name": "balancer",
"can_run": true,
"error_string": ""
},
{
"name": "hello",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
},
{
"name": "influx",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
},
{
"name": "iostat",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
},
{
"name": "localpool",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
},
{
"name": "prometheus",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
},
{
"name": "selftest",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
},
{
"name": "smart",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
},
{
"name": "telegraf",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
},
{
"name": "telemetry",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
},
{
"name": "zabbix",
"can_run": false,
"error_string": "Interpreter change detected - this module
can only be loaded into one interpreter per process."
}
]
}
Usually the Ceph documentation is great, very detailed and helpful.
But I can find nothing on how to resolve this problem. Any help is
much appreciated.
Thank you / Best regards
Ranjan
