Mod note:
For anyone reading this thread in 2018 or beyond:
Don't try to magically "fix" your hard drives. Even if you could, their firmware presents an interface far too abstract for you to accomplish anything meaningful.
If your drives are failing (in other words, presenting bad sectors or read/write errors or the like, not interface issues like CRC errors), replace them:

I am running a 6-disk setup in raidz2 (ZFS) and I recently noticed the following message:
Sometimes the above messages shows up a few times (only on ada2) and sometimes it doesn't show up.
Does this mean that one of the 6 harddisk is damaged and will soon stop completely? Or how do I need to read this?
And does this that I need to replace the harddisk soon? Since I am still pretty new to FreeNAS (and FreeBSD) is replacing a harddisk a raidz2 difficult within FreeNAS? Any pointers and / or advice?
I am really scared to lose any date...
Oh and, according to FreeNAS' Alert System it says: OK: The volume storage (ZFS) status is HEALTHY
Also scrubbing doesn't show any other errors. I am only getting messages like the one above...
