Hi all,

ovirt 4.1 hosted engine on 2 node cluster and FC LUN Storage

I'm trying to clear some task pending from months using vdsClient but I
can't do anything.  Below are the steps (on node 1, the SPM):

1. Show all tasks:



















*# vdsClient -s 0 getAllTasksInfofd319af4-d160-48ce-b682-5a908333a5e1 :
     verb = createVolume         id =
fd319af4-d160-48ce-b682-5a908333a5e19bbc2bc4-3c73-4814-a785-6ea737904528 :
       verb = prepareMerge         id =
9bbc2bc4-3c73-4814-a785-6ea737904528e70feb21-964d-49d9-9b5a-8e3f70a92db1 :
       verb = prepareMerge         id =
e70feb21-964d-49d9-9b5a-8e3f70a92db1cf064461-f0ab-4e44-a68f-b2d58fa83a21 :
       verb = prepareMerge         id =
cf064461-f0ab-4e44-a68f-b2d58fa83a2185b7cf4e-d658-4785-94f0-391fe9616b41 :
       verb = prepareMerge         id =
85b7cf4e-d658-4785-94f0-391fe9616b417416627a-fe50-4353-b129-e01bba066a66 :
       verb = prepareMerge         id =
7416627a-fe50-4353-b129-e01bba066a66*


2. Stop all tasks (repeted for every task):

*# vdsClient -s 0 stopTask 7416627a-fe50-4353-b129-e01bba066a66 *
Task is aborted: u'7416627a-fe50-4353-b129-e01bba066a66' - code 411

3. Tring to clear tasks:

* # vdsClient -s 0 clearTask 7416627a-fe50-4353-b129-e01bba066a66*
*Operation is not allowed in this task state: ("can't clean in state
running",)*



*On Node 01 (the SPM) I have multiple errors in /var/log/vdsm/vdsm.log like
this:*

Can you help me?

Restart hosted engine don't solve the problem

Thank you


p.s. Related question: tasks above are the same/related reported by the
engine in the screenshot here? https://snag.gy/XDmoUt.jpg ... How Can I
clear also these tasks from engine?
