<div><span style="font-family: arial, helvetica,sans-serif; font-size: 10pt; color: #000000;">Yes indeed I had some connectivity troubles on this server, a strange bonding problem I am investigating on since yesterday. But with just one link, it is working ok, I have no similar errors after the ones you saw.</span></div>
<div> </div>
<div><span style="font-family: arial, helvetica,sans-serif; font-size: 10pt; color: #000000;">What can I do to really remove the task from the list ? Manual database cleanup ?</span></div>

<div>According to the logs, it seems that you had some connectivity issue while you tried to preview the snapshot.</div>
<div>The preview operation rolled back but according to you failed to finish.</div>

<div>It seems like you still have a connectivity issue with that host (<span style="color: #222222; font-family: arial, sans-serif; font-size: small; font-style: normal; font-weight: 400; letter-spacing: normal; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; background-color: #ffff00; float: none; display: inline;">'pfm-srv-virt-1.pfm-ad.pfm.loc</span>), try to see what happens to it.</div>

<div>Thanks for your reply.</div>
<div> </div>
<div>Yesterday, I realized I was doing nothing good with some the software I planed to install in a VM, so I tried to revert to a snapshot a took just after OS installation, as I always do.</div>
<div> </div>
<div>As I had added a second disk to the VM in between, I choose to revert to snapshot without taking care of the second disk contents.</div>
<div> </div>
<div>But the preview operation never ended. So I restarted the engine vm but nothing changed.</div>
<div> </div>
<div>This morning I tried to cleanup things, using "taskcleaner" and "unlock_entity". I could regain control over the VM, but the task is still in "finalizing" state in the GUI.</div>
<div> </div>
<div>I even remove the second disk to see if it was better, but nothing.</div>
<div> </div>
<div>You will find the engine logfile and the "vdsm.log" from the server the task is running on.</div>
<div> </div>
<div>I am not sure how to check engine version precisely, so I queried the rpm database in the vm : ovirt-engine-4.2.2-1.el7.centos.noarch</div>
<div> </div>
<div>Regards</div>
