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
