Volume Import: Folders Empty due to Encrypted Discs?

[Aaron Chamberlain]

I'm semi-new to FreeNAS having configured a few systems but never in this fashion. A colleague in my University Department told me that they had an "old" (2014) NAS that wasn't working and if I could take a look. Turns out it was a FreeNAS 9.3 Install with a single pool of 2x4TB Western Digital Black Drives and 1x500GB Western Digital Blue Drive named "data". FreeNAS was running from a flash drive, but it's nowhere to found, so obviously the original configuration is not known to me. They couldn't give me much more information beyond that because the Grad Student who set it up has left and wasn't available.

So I dropped FreeNAS 11 on flash drive, did a Volume Import, and it found the ZFS pool of all 3 disks, including all the folders, but there are absolutely no contents in the folders (as determined by the fact that they are all 96KB in the FreeNAS GUI and running "ls -a" in the CLI returns nothing. The GUI reports them all as Healthy, so that doesn't seem to be the problem. I haven't upgraded the ZFS Flags yet from what they were on 9.3, but I don't imagine that being a problem either.

Could it be that the disks are encrypted and this is disallowing me from viewing files? Should I just detach the Pool and then run Volume Import this time as if they were encrypted?

Any way to approach this logically in hopes of restoring data? Their data hoarders so I'm sure they won't just let me wipe them easily.

It wouldn't mount if it was encrypted as you would have to supply the keys to unlock the volume.

That's what I figured, but can't seem to think of anything to marry the two truths I'm hearing from them. They claim they were regularly backing up to it and that data is present on there, but I'm not seeing it.

Maybe I need to configure user permissions?

EDIT: The default exists right now, which means root is the owner of all the directories and has read, write, execture permissions.

Did they have replicated snapshots configured? Run the command zfs list -t snapshot and paste the output using the [ code ] tags.

Smells like directories mounted over datasets or vice-versa.

Let's start with the simple stuff: what percentage of free space does the GUI display for the whole pool? If used is non-zero, some juggling of mounts may be necessary.
If it's zero, they should invest in a /dev/null device that uses less power than a server.

No snapshots from running zfs list -t snapshot except for the one automatically created when the new FreeNAS 11 flash drive attached to the existing pool.

Says only 9.9 MiB (0%) is used on the pool with 3.6 TiB available, since they are using one of the 4TB HDDs for redundancy.

EDIT: So I'm gonna say that there's no data on Disc. Don't know where it went since they claim they were backing up to it. If no one else has an idea, I'm probably just going to wipe it, and move them to a larger pool since they want to move 3 TB of stuff they have a Google Drive down to the server.
