Dear All,
old snapsahots seem to be the problem. In fact domain DATA_FC running in =
3.5 had some
lvm snapshot volume. Before deactivate DATA_FC=C2=A0 I didin't remove thi=
s=20
snapshots so when
I attach this volume to new ovirt 4.2 and import all vm at the same time =
I also import
all snapshots but now How I can remove them ? Throught ovirt web=20
interface the remove
tasks running are still hang. Are there any other methods ?
Thank to following this case.
Best Regads

All,<br I
have been
using ovirt
for a long
time with
three
hypervisors

<br This
three
hypervisors
have HBAs and
access to

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

with
taskcleaner.sh
I can't do
anything and
then I need to
know how I can
delete the old

3.5 without
