Hard drive errors, how to tell if replacement is needed?

[Lycergician]

Hey,

Been running the latest stable Freenas 10 (haven't upgraded to 11 yet) on a 32 gig ecc xeon on a Supermicro x10sl7-F with the built in Lsi 2308 flashed to the correct bios for 10 (I forget the exact lsi, 16?)

Have 4, 4 TB drives in striped mirrors. Been working flawless, and still is but have been getting some write errors as pasted in below. The errors were at 6, cleared them, didn't see anything for a few months. Now at 9 on a drive.

Checking status of zfs pools:

using 'zpool clear' or replace the device with 'zpool replace'.

Should I replace the drive? What steps can I take to check to see if the drive is still "OK?" This should be an HGST Coolspin 4TB drive that is less than a year old. I ran full HD tests before I installed the 4 drives and everything came back clean about 10 months ago.

Thanks, my first Freenas box and was looking to upgrade it to 11, but wanted to make sure the drive is ok first.

Thanks for any pointers.
