Ok so i have no idea whats going on or how to fix it. These are brand new hard drives that have only been in my freenas box for less than a month. There is no way there should be any problems with the drives. I dont exactly know what people need to know how to fix this but maybe this link should help. I dont know what any of it means. Please help? http://illumos.org/msg/ZFS-8000-8A

Were they tested/burned in before you started using them? You have checksum errors..

It would be useful if you posted server specs, the actual message, etc... you know.. like the forum rules ask for? ;)

How long ago was the system built? Did you not test ram or hard drives at all? Please post the full output (use putty) of "zpool status -v"..

Also the system doesn't meet ECC ram requirements.. It also has a Realtek LAN chipset which you might have problems with due to the low power from Celeron..

The system was built over a month ago. No i did not test them because clearly it was working for over a month. I dont know how to do what you are asking because i dont know computer code like you do so youre gonna need to walk me through what you are asking for. And this system is in a mirror array. Clearly one hard drive is working. Isnt there a way to wipe the hard drive thats giving corrupt data and rebuild it using the drive thats having no issues? Or would that not work

yeah.. I'm gonna bow out here.. realtek NIC, non-ECC RAM.. this is a disaster in the making.

Good luck!

Please download putty..
http://www.chiark.greenend.org.uk/~sgtatham/putty/

Ensure SSH is enabled in FreeNAS services.. (Is SMART enabled in FreeNAS Services?)

create an SSH/putty shell into your freenas box..

once logged in

run "zpool status -v"
run "camcontrol devlist"

Post the output here in code tags..

If you are getting degraded alert there is something obviously wrong.. I'd create a few more copies of that data!..

Did you run any testing at all (on ram /cpu/hdd) was the ram working pulls or new? Do you have email setup on the FreeNAS box?

Please ensure you have reviewed http://doc.freenas.org/index.php/Main_Page

Thanks,

sorry forgot to mention i only own macs so i can't use putty. But here is what I've done.
I went back to the disk that was showing checksum errors and brought it offline
After that i wiped that disk with zeros to clear any data that was on it.
I then resilvered the wiped drive to bring it back into the mirror and turns out all the checksum errors disappeared and my volume status returned back to healthy instead of degraded. Not sure what caused it to degrade in the first place but wiping the drive and brining it back into the array seemed to do the trick.

Im not sure if this is the same as what you were asking me to do using putty but i went into my shell and did the same commands and came back with this...
Im assuming all is good now?

Lol awesome help guys.

And what.. you expect us to bend to your needs? Sorry, this is a VOLUNTEER forum. Nobody is paid to be here, and nobody is being paid to help you either.
