I will try to be short, I had FreeNAS system with 2 USB drives mirrored as boot devices and one of them failed today.
While trying to remove the failed USB and replace with a new one, I accidentally unplugged the good one which made it corrupted and no longer boot (will go to grub).
Trying to install FreeNAS and use "upgrade" so I could save the configuration file failed every time so I went to plan B - install FreeNAS from scratch and then connecting the corrupted USB so I could access it and retrieve the configuration file.

Right now I'm stuck as I can't access the files or to copy them even though I mounted the zpool and it show online.
The corrupted USB is "da1" under "oldpol"
Would love to get some help on how to access / copy the files from that dataset so I could retrieve the configuration file and go back to normal.
Thank you very much

Zpool status show:

In this case - even though the mount point show "/mnt/Main/oldbot" and "/mnt/Main/oldbot/ROOT" - those folders are empty when I'm trying to access them via shell
