Hi
I've had problems before with GEOM mirror and my SATA drives, and
i've posted about it here before too. The solution seemd to be a
change of motherboard, this reduced the crash very much (and also
the speeds archieved was greatly improved, from 10-15MB/s to
40-50MB/s..).
However after the change i had one or two crashes, but now it has
been running for well over 50-60 days or so without any problems.
Then, 11 days ago I upgraded to 6.1... And now I got these
"crashe"s again (the mirror is crashed that is, the system still
runs fine):

Anyone got any new clues? Afaik the disks should be working fine
(they are 6 months old and this same problem has occured multiple
times...)
Hope to solve this ;)
Thanks
Johan

However no read read timeouts etc as before, just this. 18 days
uptime this time (i've rebooted for other reasons since last mail).
It always seems to be ad4 that is disconnecting.. I'm going to do
some disk tests on it but i doubt it will give anything since i've
had similiar problems from day one (did tests at that time w/o
problems) with this gmirror setup (new disks).
Johan
Followup, I ran over the disk with Maxtors own test program, full
length test. Not a single problem.
After reboot the raid is rebuilding fine:
GEOM_MIRROR: Device gm0s1: rebuilding provider ad4s1.
As usual it seems i cannot get the controller/driver to redetect the
disk using atacontrol etc..
