@rzr Updates installed and running. I also run the snapshot-fixer.py and xapi_leaked_vbds.py scripts... The fixer found/fixed lots on many pools... @andriy.sultanov I have the same error... On one pool, I ran snapshot-fixer.py and it fixed about 50 of them, but xapi_leaked_vbds.py still returns an error (before and after fix): Traceback (most recent call last): File "./xapi_leaked_vbds.py", line 23, in <module> snap = xapi.VM.get_parent(snap) File "/usr/lib/python3.6/site-packages/XenAPI.py", line 317, in __call__ return self.__send(self.__name, args) File "/usr/lib/python3.6/site-packages/XenAPI.py", line 198, in xenapi_request result = _parse_result(getattr(self, methodname)(*full_params)) File "/usr/lib/python3.6/site-packages/XenAPI.py", line 292, in _parse_result raise Failure(result['ErrorDescription']) XenAPI.Failure: ['HANDLE_INVALID', 'VM', 'Ref:119']
