I recently implemented a RAID-1 solution into my existing webserver. To do this I bought 2 identical brand new hdd's. I set up a raid and synced the drives per the handbook: http://www.freebsd.org/doc/handbook/geom-mirror.html
All was fine and gmirror status showed a status of 'Complete'. However today (about 3 days after the implementation) I had tons of error messages like the below appearing in my logs:
And of course when checking the results of gmirror status I see that the mirror is 'Degraded'.
Assuming ad1 isnt bad already, what can I do? Is it likely that I bought a faulty hdd?
