Read SMART Error Log Failed

Device: /dev/ada4, Read SMART Error Log Failed
Device: /dev/ada5, Read SMART Error Log Failed

I built a NAS server not so long ago, and got 6 WD red drives in there.

Recently I've been getting these emails, and made nothing of it, however now it happens almost monthly.

It started out being ada2, then ada4 now its ada4 and ada5.

Can anybody give me a straight answer to whats happening here? Should I be worried?

Bump :/

What OS is the the NAS running?

FreeNAS latest version

First, i would recommend reading this and check the drives health and test the drives with smartctl. On the second link the examples on how to use it will be the FreeBSD ones since under the hood FreeNAS is FreeBSD bundled with a few other things. You are going to need to SSH into the the FreeNAS box and su into a root shell to run the commands.

smartctl is now running, will keep you posted.

Results are in, however I am not sure how to read them.

/dev/ada4
