I just had to reboot my TrueNAS server. Upon reboot, I successfully decrypted my main dataset, but I couldn’t decrypt my GELI-encrypted SSD dataset – it threw an error despite me using a password manager.
Upon further inspection on the “Pools” page of TrueNAS, the SSD is assigned to pool “N/A”, and zpool status -v doesn’t list the pool at all. The SSD has, however, just passed a short SMART test, and the pool continues to appear in TrueNAS’s “Pools” page.
There are no alerts from TrueNAS about this.
So it would appear that the SSD became detached from its pool somehow, that ZFS knows this, but that TrueNAS partly does and partly doesn’t.
My only option in the pool’s pop-up menu in “Pools” is “Export/Disconnect”, so it seems that this is the only option I have, barring something in the terminal. But before I pull the trigger, I wanted to ask if this is indeed the way to go, and what else I should do to get this pool back online.
Sure. Here’s the info you requested. My hardware and TrueNAS details are in my sig.
$ zpool status

status: Some supported and requested features are not enabled on the pool.
The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(7) for details.

As you can see, I only have my boot and storage (tank) pools. The pool that disappeared was named “SSD2”, and it’s not here.
$ zpool import
no pools available to import
Note that both my boot and tank pools are already mounted.
Yes, it’s a single-drive pool. Used for a VM and some jails.

I’m running the long SMART test right now.
The story here is that this pool was single-disk for a long time, and, realizing the error of my ways, I bought another 2TB SSD to make it into a mirror. But it turned out that the new SSD was like 400 MB smaller than the old one, and so TrueNAS wouldn’t let me use it to make a mirror. So I repeated the process with a different 2TB SSD and… same story!
ada3 is the third SSD I’ve bought in an attempt to turn this pool into a mirrored one. It’s actually big enough to do this, but TrueNAS failed twice when trying to add this disk to the pool. The first time the error was [EFAULT] Failed to wipe disk ada1: [Errno 1] Operation not permitted: '/dev/ada3', and the second it was [EFAULT] Unable to GPT format the disk "ada3": gpart: geom 'ada1': File exists.
That debacle is documented here in case you’re interested. I still haven’t been able to solve it, and have just left the disk in in the meantime. (If you do read it, ada3 appears as ada1 there; the disk was on a different SATA port at the time).
The drive is healthy, and I have no clue why it is not even presented as an importable pool.
Mayebe someone having experience with GELI encryption would have an idea?
This just shows partitions and their limits. The main teaching is that… ada1 is NOT there although it is listed by camcontrol and should have partitions.
Do you see an “Export” button in the GUI for a pool which is not in zpool status and not available to import? I suppose that you may try (don’t tick the box to wipe the pool!).
Yeah, should being the operative word there, but doesn’t appear to have them anymore. Those attempts to mirror the drive appear to have nuked the partitions.
In theory one can restore a partition table, but that’s black magic to me and I don’t know how to go about it or if it even applies to this case (it might just be when it’s “corrupt” as opposed to gone) Plus it’s an SSD, so I am not sure how well that jives with scanning for the lost partition table.
It may well be too late at this point.
Does specifying the device with gpart /dev/ada1 show anything?
Is testdisk available in CORE?
Partitions were purposefully nuked during the attempts to mirror the drive, but that was one month ago so I suppose that @StrandedCamel targeted the right drive…
Or not?
I’ve been using this SSD for three or four weeks, hitting it quite hard as it has some jails and a VM running on it, and I’ve had no issues. Also, a scrub was successfully run on it two days ago. The problem appeared just last night after I rebooted. So I strongly suspect I tried to nuke the right drive.
I’m still not sure how to proceed, and would appreciate some guidance. When I go to Storage | Import Disk in the TrueNAS management GUI, I get an error: Error getting disk data. I’m at a loss. What the heck do I do now?
Well, I’ve just tried to Export/Disconnect my pool, and TrueNAS fails at even that! Here’s the error:
Error: Traceback (most recent call last):

disk_path = os.path.join('/dev', d['devname'])
KeyError: 'devname'
What the heck is going on here? Everything related to this pool and disk is broken. Nothing works, and nothing has been able to solve the problems.
I should add that these problems all persist across reboots.
So my situation is that I can do nothing with the SSD in question and nothing with the pool. The SSD pool shows up in TrueNAS but not in zpool list. The SSD shows up as belonging to pool “N/A” in storage. I can’t, however, export/disconnect the pool, though I can download its encryption key. I can’t reimport it. And I can’t even try and create a new pool-- I get Key Error: devname when I try.
I suppose that you may try (don’t tick the box to wipe the pool!).
