While logged in to UMC in the UVMM module an error occured “internal server error”.
The logfile shows the following entries:
Interner Server-Fehler in "uvmm/domain/put". AttributeError: 'NoneType' object has no attribute 'status' success = result.status == 'OK' File "/usr/lib/pymodules/python2.7/univention/management/console/modules/uvmm/uvmmd.py", line 113, in response return self.response(data) File "/usr/lib/pymodules/python2.7/univention/management/console/modules/uvmm/uvmmd.py", line 106, in request return self._function( *tmp, **self._kwargs ) File "/usr/lib/pymodules/python2.7/notifier/__init__.py", line 104, in __call__ tmp = self._function() File "/usr/lib/pymodules/python2.7/notifier/threads.py", line 82, in _run Traceback (most recent call last): Request: uvmm/domain/put Interner Server-Fehler in "uvmm/domain/put".
On the host a very demanding
rsync task was running putting a very high load of I/O waits to the server’s hardware. This led to the delayed responses of UVMM.
Start your task with
ionice -c3 rsync ...
This will make sure other processes get higher IO priority when needed.
