All,<br I
have been
using ovirt
for a long
time with
three
hypervisors
and an
external
engine running
in a centos vm

<br This
three
hypervisors
have HBAs and
access to

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

So I need your
help to kill
the three

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

without having

=C2=A0=C2=A0 Dear All,
Are there tools to remove this task (in attach) ?
taskcleaner.sh it's seems doens't work:
[root@ovirt-new dbutils]# ./taskcleaner.sh -v -r
select exists (select * from information_schema.tables where=20
table_schema =3D 'public' and table_name =3D 'command_entities');
=C2=A0t
SELECT DeleteAllCommands();
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=
=C2=A0=C2=A0=C2=A0=C2=A0 6
[root@ovirt-new dbutils]# ./taskcleaner.sh -v -R
select exists (select * from information_schema.tables where=20
table_schema =3D 'public' and table_name =3D 'command_entities');
=C2=A0t
=C2=A0This will remove all async_tasks table content!!!
Caution, this operation should be used with care. Please contact=20
support prior to running this command
Are you sure you want to proceed? [y/n]
y
TRUNCATE TABLE async_tasks cascade;
TRUNCATE TABLE
after that I see the same running tasks . Does It make sense ?
Thanks
Best Regards
Enrico
