Hi,<br>
<br>
We're trying to delete an auto-generated live snapshot that has been created after migrating an online VM's storage to a different domain. oVirt version is 3.6.6 and VDSM version is 4.17.28. Most relevant log lines are:<br>

<br>
I'm attaching relevant logs (both for ovirt-engine and SPM's vdsm).<br>
<br>
What could be the reason for this error?<br>

@Nir,<br>
<br>
that looks like some issue in VDSM please have a look<br>

</blockquote>
This means there was a previous attempt to merge, and the block job<br>
did not complete yet.<br>
<br>
Engine should detect that there is an active block job and wait until<br>
it completes.<br>
<br>
This is probably engine bug, please file a bug and attach complete vdsm and<br>
engine logs.<br>
<br>
Ala, can you look at this?<br>
