Mounting UFS file systems in Ubuntu should be straight forward. Follow these simple steps to make sure that your are mounting your FreeNAS disks properly in Ubuntu:

Load the UFS module (or make sure its loaded)

sudo modprobe ufs

Make a directory where to mount the files on

mkdir ~/ufs_mount

To find out which device holds your UFS file system use the command fdisk -l, note which device you intend to mount.

Mount the file system to the directory your previously created

sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdb1 /home/<your_username>/ufs_mount
