Can't tell what HDD is failing or making it go slower

[TJ Dowling]

Can't tell why I can't copy files to/from my FreeNAS....

How can I tell what drive is bad if any?

In the Web GUI, go to Storage, click on your volume, then click the Volume Status button (looks like a sheet of paper) at the bottom. You also really need to either remove some data, or increase the pool capacity.

Or you can use the shell and type "zpool status".

OP, you have a number of issues I think. Let's start with which drive is failing.

Can you use pastebin to show the output of these commands:

smartctl -x /dev/ada0
smartctl -x /dev/ada1
smartctl -x /dev/ada2

Separate pastebin for each, and give us the links, please.
