I can'tchange cables by myself, servers are dedicated from provider, but as I can saw, they picked whole new machine from their HW storage and put new Samsung disk drives in. So these two last machines are brand new with new cables. (Probably with a same type of cables - all machines are ASUSRS120)I can confirm the same behaviour with a ULi M1689/Newcastle Athlon64 based system running 6.1-RELEASE-p3 (i386). ad6 just detaches without warning and it takes a reboot to bring it back. atacontrol reinit has no effect. Triedthe following to resolve the problems:- Changed cables (both ad4 and ad6) - Changed SATA power to legacy- Moved the NIC and anything else from the shared PCI INT (thought I'd cracked it at this point as it was stable for a month, then it lost ad6 on a nightlydump)- Remade my gmirror array as an ar. Put it straight back to gmirror again whenI found out what a pain it is to rebuild after ad6 disappears.I am not sure if it is related, but... I experienced a similar sort ofproblem, although the details in my case are quite different. What was similar was that I would "lose" two ATA drives from an array,inexplicably. Reconfiguring the same drives and rebuilding would causethem to work perfectly again -- for some number of days, after which the same failure would occur. What is different is that this was with a 3Ware RAID controller -- which made removing/raconfiguring/rebuilding much easier -- but I was seeing the exact same errors.
No your errors are not related. As of my experience (and the experience of others) the controller forgetting or loosing drives is a "feature" 3ware. We had similar problems with 3ware-7500-8 ATA controllers and i was reported of the same errors with 3ware-9000 series. Our in-house 3ware-9500S are not showing this kind of errors.
This errors are not driver or OS dependent such as they appear on FreeBSD as well on different Linux distros. Since not all controllers suffering of these errors it is maybe depending on the firmware or board/chip revisions.
