I have been using ovirt for
a long time with three
hypervisors and an external
engine running in a centos
vm .<br>
<br>
This three hypervisors have
HBAs and access to fiber
channel storage. Until
recently I used version 3.5,
then I reinstalled
everything from scratch and
now I have 4.2.<br>
<br>
Before formatting
everything, I detach the
storage data domani (FC)
with the virtual machines
and reimported it to the new
4.2 and all went well. In<br>
this domain there were
virtual machines with and
without snapshots.<br>
<br>
Now I have two problems. The
first is that if I try to
delete a snapshot the
process is not end
successful and remains
hanging and the second
problem is that<br>
in one case I lost the
virtual machine !!!<br>

<div><br>
</div>
<div><br>
</div>
<div>Not sure that I fully
understand the scneario.'</div>
<div>How was the virtual
machine got lost if you only
tried to delete a snapshot?</div>

<blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> <br>
So I need your help to kill
the three running zombie
tasks because with
taskcleaner.sh I can't do
anything and then I need to
know how I can delete the
old snapshots<br>
made with the 3.5 without
losing other data or without
having new processes that
terminate correctly.<br>
<br>
If you want some log files
please let me know.<br>
