SOLVED Can't import former proxmox pool into TrueNAS Scale

[Johnross2007]

I previously ran proxmox on this machine, but just installed TrueNAS Scale instead (proxmox is now on a new machine). When I used the Import Pool tool, it gave me the following error: [EFAULT] Failed to update properties: ZFSException('NFS share creation failed')
I will put the full error output at the end of this message. I went to the CLI to import and it said the pool was already imported. It doesn't show in the GUI. I rebooted and it still didn't show in the GUI, but it also doesn't show in the CLI for zpool list. It only shows after the failed import. This happens for both pools.

Here it the full output:

The above exception was the direct cause of the following exception:

This guy had the same issue, but didn't resolve it. He destroyed his pool instead. I'd rather not do that....

I tried it in CLI and got this similar error:

root@truenas[~]# zpool import tank
Unable to create temporary file: Operation not permittedcannot share 'tank/Media: system error': NFS share creation failed
root@truenas[~]#

 

[Johnross2007]

I fixed it! I figured some NFS flag was the issue, so I ran this command in CLI:

zfs set sharenfs=off tank

Then I rebooted, as the GUI seems confused after a failed import. After reboot, the GUI import function worked!!!!!

edit: I had to do this for every sub-pool (can't remember the technical term for this). For example, I also had to run it on "tank/Media." Maybe there's a way to do it recursively, but I'm not familiar enough with ZFS for that.
