Freenas output: should I be worried?

[dfsdfgfkjsefoiqzemnd]

I rebooted my NAS earlier this week (I turn it off when I'm away from home for a day or more) and the next morning found this message in my inbox.

da6 is one of the 8 WD Reds that make up the main RAIDZ2 pool.  The drives were all bought new in the summer of 2015

This is the second time I've seen this message for this drive, but it doesn't happen with every reboot.  Sometimes it gets no errors at all, as demonstrated by my reboot from a couple of days earlier :

Should I be worried?  Is it time to buy a couple of spare drives?  
Or did I indeed read that it is a CRC error, which means that fiddling with the cable could do the trick?

what does smart data say?

[dfsdfgfkjsefoiqzemnd]

No idea, I can't get a proper smart reading. 

smartctl -a /dev/da6 gives an answer that's larger than the shell window.  Scrolling up is not an option.

 

If it makes any difference : I'm still on 9.3 , haven't updated yet because I've always been too busy to flash my HBA from firmware 16 to 20.  (last time I had to flash it, it took hours of preparation because I had to tear half of my main PC down to make room for the card.  Not looking forward to doing that again)

The "normal" way to get the whole smart message would be to connect via SSH i guess.. but to get it done quickly, you can just type "smartctl -a /dev/da6 >> smart.txt" and the read the file with nano or w/e tool you prefer i.e. "nano smart.txt" and later delete it.

 

the screen does not show any longer smart test, do you have a task for those set?

 

EDIT: is this the first time the error showed up? you might also check your SATA cable, heard a bad one produces errors like this.

[dfsdfgfkjsefoiqzemnd]

I didn't set up any tasks etc at all, merely configured the pools and started using the NAS.  Only times I've ever used the control panel was to apply updates.

I don't mind setting stuff up, but once it works I prefer to not mess with settings and command lines etc.  I honestly never looked into mastering Freenas, all I want it to do is to store my data and to have it accessible to my PC and laptop.

Classic case in point : I can't figure out how to copy-paste the text here or save the file locally.  At least I'm good with Paintshop, so here's a stitched-together screenshot.

 

 

 

It looks like I've got CRC errors indeed.  Perhaps it's time to upgrade my SAS->SATA cables, IIRC those were no-name ones that I quickly ordered because the LSI card didn't come with any.

Funnily enough, I have a 4-drive (256GB 850PRO) RAID5 array in the main PC that kicked one drive out due to CRC errors too.  Been meaning to fix that for months too, but time is always an issue.
