SOLVED Dying drive, I think

[aussiejuggalo]

Started having some problems about 5 months ago with a drive but was to busy / lazy to deal with it until I noticed 2 LED's on my HDD bays were off and only flashed red instead of soild blue, 1 drive I know has problems but I can't seem to hunt down the other drive in FreeNAS atm (unless the bay is just being stupid).

Drive da2 started having S.M.A.R.T. errors, I didn't think to much of it at the time but after finally getting around to running a long self test (I still haven't setup auto tests, I know stupid) it's coming back with "2 Currently unreadable (pending) sectors" & "Self-Test Log error count increased from 4 to 5". I've got 2 spare drives ready to go in if I have to replace it so that's not a problem.

So what do you think does it need to be replaced?

Quick question on S.M.A.R.T. tests can I run long tests on all the drives at once? same question about short tests.

Thanks :).

So what do you think does it need to be replaced?

Yes, that drive has been having read errors for the last 453 hours of it's life :-( (actually it's more)

Yes, log in to your Secure Shell and start those tests as fast as you can type the commands for each drive,
I would not bother with the short tests though...

The disk should still be in warranty, so RMA it. Failing SMART tests are plenty of justification for that.

Didn't realise it'd been having errors for that long oh well lol.

Why shouldn't I bother with short tests? I thought you use short tests every few days to a week then long every month.

Yeah it's still under warranty, only bought it at the start of last year so I'll RMA it.

The long test's read/verify segment tests the entire disk no matter how long it takes, the short test is
performed over a much smaller segment and is limited by time.

Ah ok, so how should I set the long tests up, once a month or a every 2 weeks etc?

 

[danb35]

how should I set the long tests up, once a month or a every 2 weeks etc?

For regular SMART tests, I run a short test daily and a long test weekly.

 

[BigDave]

I was suggesting only doing the long tests for a more immediate evaluation of your drive's current condition.
Not as a matter of standard maintenance. Sorry for the confusion...

Thanks, gonna try the short tests for this week and if they bug me I'll stop them.

I'll run long tests tonight on all the drives and see what they say before I replace any of them, hopefully no more than that 1 drive needs replacing.

 

[aussiejuggalo]

So been waiting for the last couple of days for long tests to run, however for some reason there not running even though I scheduled them. I set them to run at 11 pm for the last couple of nights but they haven't run, the short tests run fine every day though. Posted a pic of my S.M.A.R.T. tasks tab to see if I screwed up anything.

Also 2 quick questions

1. I was told recently that I need to keep half my pool free for cron jobs etc, is that true? my setup is 8 4TB drives in RAIDz2 on one pool so... heaps of storage and heaps unusable if that is true.

2. Is there a way to see current running S.M.A.R.T. jobs?

Thanks

 

[danb35]

I was told recently that I need to keep half my pool free for cron jobs

Not even close to true. Either someone's very badly misinformed, or you're very badly misunderstanding what they're saying.

Edit: I don't see anything wrong, as such, with your SMART test setup, but it's much more complicated than it needs to be. A single entry for the short tests on all drives, and a second entry for the long tests on all the drives, is all you need. No need to have a separate entry for each drive.

Edit 2: Just kick off the SMART tests at the CLI for now. smartctl -t long /dev/da0, repeat for each drive. After whenever it tells you to expect the test to be done, check the results with smartctl -a /dev/da0 (and again, repeat for each drive).

Probably misunderstanding them, it was on another forum where I did a build log for my NAS, this is what they said:

Also to add you want approx 1/2 free drive space ( in your case 9 tb). For everything else you dont see (cron jobs ect) on freenas

What i will be doing is making multiple zpools. That way muy personal media can be on smaller safer hard drives ( by safer I mean quicker to copy vs large
Large hdds ) and my media on large ones

freenas likes 50% freespace !

Oh, didn't realise you could select all drives at once, my bad .

Ah ok, I'll do that in a bit. I've got emails set up now to so I should get them hopefully.

 

[danb35]

this is what they said:

No, I'm going to say they're just wrong. Sure, any CoW filesystem (like ZFS) likes its free space, but we normally recommend at least 20% free (i.e., your pool not more than 80% full). There are use cases where we suggest more free space, mainly involving lots of VM storage and/or iSCSI use, but the general purpose recommendation is at least 20% free. And cron has nothing to do with anything.

 

[aussiejuggalo]

Ah ok, well I always have a rule with HDD / SSD anyway no more then 90% used even if it means buying a new drive.

Got around to replacing this drive today, reslivering atm. It threw me for a second though because it said "replace drive da7" then I realised either FreeNAS or the RAID card swapped the order of the drives, a quick check of the serials and I realised it was the right one, now to play the waiting game.

Got one more question, is it better to have 1 big pool like I have (8x 4TB in RAIDZ2) or 2 smaller pools? I mean better as in reliablity, resliver etc.

Thanks.

Edit, submitting the faulty drive for RMA, hope none of the others die in the mean time .
