Hi, We have 4 hosts on Version 4.2.1.7-1.el7.centos, but we have got an issue with vdsm on our SPM which is causing some issues and we cannot migrate any VM's from that host. If I run 'vdsm-client Host getAllTasksStatuses' on the host, it returns 4 tasks, message: running job 1 of 1, code:0, ........ taskState:running for all 4 tasks. However we have no operations in the engine that should be running (not a hosted engine), just a stuck task that logs every minute or so 'Clearing asynchronous task Unknown that started at Thu Dec 06 14:42:03 GMT 2018'. If I try to manually stop the task, 'vdsm-client Task stop taskID=' we get 'code=411, message=Task is aborted: u'task guid' - code 411'. So then If I try and clean the task it can't because its in a running state: vdsm-client: Command Task.clear with args {'taskID': 'task guid'} failed: (code=410, message=Operation is not allowed in this task state: ("can't clean in state running",)) Attached is part of the (sanitised) VDSM log that is recurring. VDSM version is: vdsm-client-4.20.17-1.el7.centos.noarch Does anyone have any ideas other than shutting down all the VM's on that host and restarting it? Not sure if I can restart the VDSM service with VM's running? Thanks, Nick
