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.
