Install the smartmontools from

and post the output of
smartctl -a /dev/ad8
smartmontools was previously installed and running as daemon without
any bad reports.
I can not run "smartctl -a /dev/ad8" now, because my server housing
provider replaced HDD with the new one and after an hour of
synchronization "ad8: FAILURE - device detached". So provider
replaced whole server, only ad4 is original piece of HW.
On new server synchronization was much faster then in previous server
(1:30 hour compared to 5 hours in previous server) - so I think it
was HW problem.
Now I am running stresstest with copying /usr/ports to another
partition in infinite loop.
I will post results later. (On bad server, test failed after about 30
minutes. On another server the test is running fine second day, so I
think if disk will not fail after 1 day, problem is solved)
At last - now I think this was not GEOM/gmirror related. I tried
remove ad8 provider from gmirror (gm0), boot up system from gm0 with
one provider (ad4) and test ad8 mounted separately - ad8 failed again.
Just got another one..

6 days uptime when this occured... Both disks are tested with PowerMax
without a single problem (same with smartctl), both SATA cables are
new. So the only hwproblem that I cant rule out would be the mobo, but
that is quite new too...
Solutions? Try RELENG_6 as recommended earlier?
In my case, server (mobo) replacement solved the problem. In this time,
I got same problem on the second server. :(
You can try BIOS update first, then RELENG_6 (I do not thing it helps),
at last - replace mobo.
Please, send me info, if BIOS update solved your problem.
