My dmesg shows the following (extract):

However, smartctl -a /dev/ada0 shows no errors. I've ran a short and a conveyance test on the disk and no errors are shown.

This is on a Proliant Microserver Gen8 with 2 x 3TB and 2 x 1TB Western Digital disks. The error refers to one of the 3TB disks. FreeNAS is running with 12GB RAM.

Should I be worried about the messages, given that there are no SMART errors?

Welcome to the forums :)

This is typically indicative of a bad cable (SATA or power). If smartctl is not showing any errors and you're running regular short and long SMART tests then it's the most likely cause.

I powered off, reseated all the disks and fired it up. No errors :)

Hi all, think i have the same problem here.
Could you please tell me how to run the smartctl check?

Thanks in advance.

Have you tried doing the same? Replace the cable for ada1. Also, suggest you create your own thread instead of hijacking this one.

yes i've tried replacing the sata cable, but didn't worked.
So i'd like to discard the faulty disk option.
