Are there tools to remove this task (in attach) ?<br>

select exists (select * from information_schema.tables where

t<br>
This will remove all async_tasks table content!!! <br>
Caution, this operation should be used with care. Please contact
support prior to running this command<br>
Are you sure you want to proceed? [y/n]<br>
y<br>
TRUNCATE TABLE async_tasks cascade;<br>
TRUNCATE TABLE<br>
<br>
after that I see the same running tasks . Does It make sense ?<br>

<div class="moz-cite-prefix">Dear All,<br>
old snapsahots seem to be the problem. In fact domain DATA_FC
running in 3.5 had some<br>
lvm snapshot volume. Before deactivate DATA_FC I didin't
remove this snapshots so when<br>
I attach this volume to new ovirt 4.2 and import all vm at the
same time I also import<br>
all snapshots but now How I can remove them ? Throught ovirt
web interface the remove <br>
tasks running are still hang. Are there any other methods ?<br>
Thank to following this case.<br>

All,<br>
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>

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>

If you want
