4 years in, first failing drive? Weee!

sremick · Nov 28, 2018

So I've been running my FreeNAS box for a tad over 4 years. Looks like I might have my first failing drive. Unfortunately a changed email password resulted in me not getting automatic notifications, so I caught it by chance while in the GUI for another reason.

Code:

CRITICAL: Nov. 28, 2018, 4:02 p.m. - Device: /dev/ada2, 1 Currently unreadable (pending) sectors

Just 1 sector? Hmm.

So, please guide me so I don't fsck this up. Options:
A) "It's just 1 sector. Do _____________________ and you should be fine (unless you start seeing more bad sectors)"
B) "You probably should replace the drive, but you're probably fine to use the NAS in the meantime."
C) "SHUT THAT BABY OFF ASAP UNTIL YOUR NEW DRIVE ARRIVES!!!"

Fear not, I have tried to RTFA and I have this link on speeddial for when the time comes:

(this is not mission-critical, so that's why no cold spare)

I just noticed that the SMART tests weren't running. :( This was mysterious and frustrating since I know I read about doing this and clearly remember creating the tasks.
So I go and look... sure enough, the tasks are there... but I now see an UI thing I didn't notice before: although it lists all the disks, you actually have to ctrl-click on them to select the disks you want that scheduled task to run on. Doh! That wasn't really obvious (I saw them displayed and just thought it ran on the displayed disks). Suffice it to say I've remedied this.

sremick · Nov 28, 2018

So I took the opportunity to manually run short and long tests on all 6 drives. I happen to notice the following on the console:

Code:

Device: /dev/ada3, Self-Test Log error count increased from 15 to 16

Another drive? :(

It seems your ada3 has been failing smart tests since its 12714 hour anniversary.... and it's now over 35k hours!

I'd be more concerned about this.
I'd advise to change this drive. You could also try to wipe the drive and restart a long test to see if it was an unreadable sector and if it has been remapped... (that's what I did on my backup system but... it's backup so less critical).

For ada2, depending on your sensitivity and on the importance of the data, you could either wait to see if the count of currently unreadable (pending) sectors is rising or not. But I would monitor that closely.

Let's see also what other forum members advise...

But keep in mind, I suppose you have a RAIDz2 pool and now 2 disks have issues (they are not failing but those are indicators) and you have 2 disks redundancy... so, still ok but not the most comfortable!

Typically, between 4 and 5 years of wear is where drives fail most frequently. Around the beginning of this year I had to replace all the drives in both of my FreeNAS systems because they were all over 5 years of age and I was loosing a drive or two every month. So I bought a case of drives:

I have 12 dries in each of my two home FreeNAS systems... Drives don't last forever and it is time for you to start preparing.

PS. Your ada3 drive needs to be changed ASAP and I would change ada2 also. These drives are of an age that they are ticking time bombs.

I do suggest used SSDs for boot drives but for storage drives I recommend new. I have done the used drive thing for my personal storage, but those drives have a higher failure rate and I don't suggest that unless you really can't afford new. If I were buying drives and I couldn't afford new, I would probably go with something like this:

Well I've got one new drive in to replace ada3. Currently doing a burn-in and test on a separate computer. My intention was always to replace the 3TB drives with larger as they failed, so that eventually when I replaced the 6th drive poof more storage, so this burn-in might take a while (8TB).

I recently did a burn-in on 6 TB drives and I think it was three days.

These big drives are really fun...

Just an update that the burn-in and replacement process of ada3 went fine.
Main issue now is the alternate screw spacing on the high-capacity drives that does not line up with the 4 holes my Node 304 uses.

That is pretty terrible, but you might be able to get replacement drive brackets from the manufacturer. I remember some other people running into that problem.

That is pretty terrible, but you might be able to get replacement drive brackets from the manufacturer. I remember some other people running into that problem.

Haven't heard back from them yet, but from what I've read they don't sell just the brackets. There also used to be an adapter/shim they sold on the website but it's out of stock with no ETA.

The new Node 304s come with modified drive brackets with a 5th hole. But they won't sell just the brackets to all the previous owners?

I'm seriously considering buying a new case, taking the brackets, and then reselling it on eBay w/ my original brackets (being up-front about it all of course). Whatever loss I take is effectively my cost for the brackets.

I looked into it a little and I don't think the brackets are interchangeable. You would probably need to move your build into the new case and sell the entire old case.
