Swapped Disk Still Degraded

[Colin Fox]

Currently running the latest trueNas. I had a WD 3TB drive that was showing up as having problems. I bought a replacement drive - actually I bought 3 just to be save. This was a 4TB drive, as the store was out of 3TB's. Both the original drive and the new drive are WD RED drives.

When I did the swap, I didn't do anything in truenas first (so the drive remained configured and reporting errors). I powered down the machine, pulled the drive, put the new 4TB drive in it's place, and powered it back up. The original drive was in the list as "ada5", and the new drive came up as "ada5" as well, but now showing the new serial # and new size.

I've tried running SMART tests & scrubbing the pool, and nothing is helping. So either this brand new drive is also having problems, or there's a hardware issue, or there's still some step I need to take in TrueNAS.

I don't recall seeing any explicit instructions on what to do when replacing a drive - do you have to take it out of a pool first, or do any software reconfiguration, or are you normally supposed to just be able to shut it down, swap the drive and start it up, and it magically works? Did I miss something?

Any help would be greatly appreciated.

Seems that you might have an SMR drive there if it is a RED and not a RED PLUS which will not play well with TrueNAS.
From your description you did not do a "replace " ?

[NugentS]

zpool status -v
smartctl --scan
Please
It would also help if you followed the forum rules and posted your hardware setup

Did you click the replace button under the drive section?

Thanks for the link - I hadn't seen these docs before. I did not "offline" the disk before removing it, so the subsequent issues are quite likely based on that.

NugentS asked me to run zpool status -v & startctl --scan:

Since I replaced it without offlining first, how do I recover from this point? I tried offlining the current disk, but it just says "Faulted" and doesn't go offline.

 

[Colin Fox]

Did you click the replace button under the drive section?

Yes. I didn't offline the original problem disk. I just told the software to shutdown the computer, then once it shut down I pulled the old disk and inserted the new one and did a "Replace". Once it finished whatever it was doing, it indicated the new drive details (4TB instead of 3TB) but was still showing it having errors.

 

[Alecmascot]

Not offlining, but swapping the disk will be ok.
The symptoms you have look like those from a SMR drive.
What are the drive models : WD40-EFAX would be SMR; EFRX would be CMR; EFZX would be CMR.

I added the details in my signature. The drive I replaced was a WDC WD30EFRX-68EUZN0, and I replaced it with a WDC WD40EFZX-68AWUN0. I originally started with two WDC WD30EFRX-68EUZN0, but did the swap after one died.

Looks like the new drive is duff.
Pull the smart data for the drive: smartctl -a /dev/ada5

I also tried the `zpool clear data` but the drive is still listed as `FAULTED`. Also, a resilvering process had started, and in the 7 hours I was gone it hadn't moved past 0% done, so I restarted the server. When it came up, the disk is still FAULTED and the pool is still degraded.

I n tbe tail end of the last smart log there are 400 crc errors and resets. Lets separate ada5 from its cabling/port. Swap it with ada4 and reboot. Do zpool clear aftedwards. Tell me about the chassis and motherboard.

Sorry for the long delay. My mobo is a Gigabyte GA-z170-hd3. Not sure what you mean by the chassis - just an ordinary PC case. Anyway - I took your suggestion and swapped the SATA cables with another drive, and when it booted, everything came up ok! It's currently resilvering, but not reporting any errors on any disk. The bad disk ada5 is now the good disk ada0.
UPDATE: After silvering, the system is all in the green, so I think the issue is fixed. When I swapped the SATA cables, I noticed that one was not very well connected, so the disk issue might just have been me not properly plugging it in.
