Bob is correct to praise LiveUpgrade. It's pretty much risk-free when
used properly, provided you have some spare slices/disks.
At the same time, I'd say that this is probably an appropriate time to
escalate the bug with support - the answers you are getting aren't
satisfactory.
I would also consider creating a user/role with zfs admin privileges
only, and trying to run the scrub command from cron as this user - I
had a similar problem with an old ZFS version which I worked around by
issuing commands as a user other than root.
