Disks failed to attach when auto importing and decrypting ZFS disks

[Dainis Berzins]

I was running FreeNAS 9.1 and started getting smartd errors occasionally on a disk that was one of three Western Digital Green 2TB disks in a ZFS volume, but FreeNAS ran well for several months. Then, after a reboot, FreeNAS failed to start. The boot failed early on with a disk-related message, ("Primary GEOM is corrupted" or something similar). My assumption was that the disk had failed and for some reason FreeNAS had not been able to handle the disk failure.

I installed FreeNAS-9.2.1.6-RELEASE-x86 on the same USB drive and can now boot and log in. I then tried to auto import the ZFS volume that I had on the 3 disks, selecting the 3 disks, browsing to the recovery key and entering the passphrase. When I click OK I get an error message saying:

Code:

The following disks failed to attach: gptid/582e2578-11bb-11e3-a71d-0018f32de2e9, gptid/57920bea-11bb-11e3-a71d-0018f32de2e9, gptid/56d22023-11bb-11e3-a71d-0018f32de2e9

I tried removing the suspect disk and attempting to auto-import, but I get the same message, although referring to only 2 disks, of course.

I had removed the disks, so I can't be certain that I have connected the drives to the same ports on the motherboard, in case that could be relevant.

My hardware:

• HP dc7800 small form factor motherboard.
• Intel Core 2 Duo
• 2 GB RAM (yes, I know it would be good to have more, but it worked well for several months)

Any suggestions for how I can manage to install the old ZFS volume?

I attach the full console output from reboot to after the attempt to auto import:

"Stupid" idea: can you try first adding more ram if u have spare ram laying around?

 

[Dainis Berzins]

If I had, I would, but the system ran just fine with the 2 Gb for several months. I am sure the performance would be better, but I doubt the limited RAM is causing this specific issue.

 

[enemy85]

Was just a try if it was easy to apply. I don't have experience with encripted volumes, but i guess they are more "heavy" to handle by the system

Sorry, that's a *really* bad reason to argue it will be okay. In fact, there's a distinct chance you've lost your data as a result of this argument.

They aren't significantly heavier to handle, but when you are short on RAM then processes terminate in appropriately and next thing you know disks won't decrypt, your zpools won't create properly, etc and we end up with oddball threads like this that nobody else has ever experienced and the error messages make it look like a hopeless situation.

So I'd upgrade to 8GB before you try to do *anything* else with your pool. Failure to do so could (and it looks like it has) cost you your data.

Of course, this is where I ask if you have backups and hope you answer with "yes"...

 

[Dainis Berzins]

Thanks for the reply. Clearly I will upgrade the RAM asap. And yes, I do have the critical data backed up, thankfully.

But is there any way to get more clarity as to why the decryption / attach failed?

Also if I have attached the drives to different SATA ports than when the encryption was performed, could that make a difference or should FreeNAS be able to deal with this?

 

[enemy85]

Freenas can handle different sata ports, that's not the problem.

 

[Dainis Berzins]

OK, good to know.

So can anyone suggest any commands I could run to try to learn more about what specifically is causing the decryption / attach to fail?

 

[cyberjock]

If its failing to decrypt with your keys then the keystore on your disks are corrupted or overwritten. Who knows why that would be the case (low RAM comes to mind....) and proving the actual cause will be nearly impossible. However, since this hasn't been a problem with users like myself who *do* use the correct amount of RAM I tend to have a hypothesis...
