Imported ZFS pool can't see any of the data

TrueNAS General

I started by exporting a zfs pool on proxmox. Installed truenas scale and imported the pool successfully as I can tell. I see the expected usage and everything looks healthy.

However when I create a dataset and share. I can’t see my data. When I look in the pools mnt folder via shell I only see 'backup data disks ’ folder those just have 'dump images private ’ folders in them.

I am guessing it has something to do with old/different permission from Proxmox (or the SMB system I ran on it) to Truenas scale.
Can anyone assist?

Digging more, my root dataset’s total allocation is only of the available space on my imported pool. So that would explain why I can’t see it. How do I get a my root dataset to include the original data on the pool?

My pool name is tank.

zfs list command output of only tank info (excluded boot-pool)

tank                                                   31.6T  29.3T  31.6T  /mnt/tank

Can see the used of tank is 31.6T
Here is the mnt output

@truenas[/mnt/tank]# ls -al
total 3
drwxr-xr-x 5 root root 5 Oct 21 13:05 .
drwxr-xr-x 3 root root 3 Oct 21 12:01 ..

drwxr-xr-x 5 root root 5 Mar  2  2025 data
drwxr-xr-x 5 root root 5 Mar  2  2025 disks

Digging down into the data/images folder that listed as 32t I found a large .raw file.

root@truenas[/mnt/tank/data]# du -sh *
512     dump
32T     images

root@truenas[/mnt/tank/data]# cd images
root@truenas[/mnt/tank/data/images]# du -sh *
32T     100
root@truenas[/mnt/tank/data/images]# cd 100
root@truenas[/mnt/tank/data/images/100]# ls
vm-100-disk-0.raw
root@truenas[/mnt/tank/data/images/100]# ls -al

Now this zfs pool was created on proxmox, then had a vm running linux w/45drive cockpit to samba share it out.
