Assuming this is the same problem that's been discussed here previously (and I think it is), I need to clarify that this is neither system-specific nor a topology issue. The problem is a firmware bug in these Seagate disk drives that causes them to report an unreasonably low temperature threshold. When the reported temperature passes that threshold, we properly decide something is wrong. Another poster reported that this problem was specific to a particular Seagate firmware revision; if it were me, I'd search the archives and get myself the less-broken firmware instead of telling FMA to STFU. ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
