SOLVED Update from 11.0-U4 to 11.1 now reports DEGRADED status on pool

Thanks for the link. One other question, how do I determine which physical disc ada2 is without pulling every disc out? Also there is nothing more that I can do at this point then other than replacing it?

 

[Ericloewe]

smartctl -a /dev/ada2 | grep Serial

 

[André Fettouhi]

smartctl -a /dev/ada2 | grep Serial

Was already aware of this. Thought maybe there was something more that could be done.

 

[Ericloewe]

Then why did you ask how to identify them?

The drives themselves look fine. Replace dubious cables and scrub the pool.

Performing a scrub of the pool now.

 

[wblock]

smartctl -a /dev/ada2 | grep Serial

That has been recommended for years, but the easier way is diskinfo -v ada2 | grep ident.

Water cooling is not necessary for a NAS. That and other gamer-type stuff can make the system less reliable, not more.

What gamer type stuff are you refering too specifically?

 

[wblock]

Water cooling, giant fans, add-on fan controllers, LED lighting, 97-button mice, that sort of thing. Some of those things have specific applications for gaming, but not so much for a NAS.

 

[Redcoat]

Overclocking?

 

[wblock]

Oh yes, definitely that too.

Swap cables, swap motherboard ports, possibly swap power cables. I'm pretty sure all this is covered in @joeschmuck's guide.

 

[André Fettouhi]

Well the scrub of the whole pool just completed and it just writes

Code:

Errors: 0			 Repaired: 122M

Something that confuses me a bit in the manual. Is a drive that has been flagged as DEGRADED considered OFFLINE and out of the pool? Because when I look at the drive that is DEGRADED in my pool, I see no Offline button only a Replace button.

 

[Redcoat]

See the manual section 8.1.10, point 1. "If there is no Offline button but only a Replace button, the disk is already offlined and this step can be skipped."

Well, I went through everything again on the server. Checked the connections again and pulled all the drives out in order to find out which drive was causing the issue. After identifying the problematic drive I turned the server on again. Now it reports the whole pool and the drive as healthy. No checksum errors at all and it has been running for 5 hours now. The new drive I ordered also arrived today, so I can switch the drive at any time. Bit unsure if I should replace it anyway now or just way and see it if the issue returns? I am getting though every two minutes in the console this warning

Code:

2017/12/18 14:49:09 [WARN] agent: Check 'service:nas-health' is now warning

Looking at the FreeNAS bugtracker this seems to be reported as bug. Or should I be concerned about this?

 

[Redcoat]

No, do not be concerned about that message.

It sounds as if replugging your drive may have eliminated the issue. I would run the SMART tests on the drive again. if it checks out OK I would continue to run the server and monitor it for any recurrence of issues.

I would just leave the drive and keep an eye on it. Making sure you have smart tests enabled and email notifications. You should also burn in that new drive to make sure it's actually ok to use.

 

[André Fettouhi]

Ran smart tests on the drive again and it came up clean. So I added the drive back into the weekly smart tests again and leave it as it is for now.
