Mounting a FreeBSD UFS hard drive on Debian/Ubuntu

F

FreeDomBSD

My storage woes continue! Because this is not FreeBSD stuff, but Debian I have thought I'd put it in OT, please move it where it should be if I am mistaken.



There is a 2TB UFS-formated hard drive in a modular non-RAID external USB enclosure.

I get this popup error when I plug the drive in and Ubuntu tries to automount:


Code: 
 Unable to access “2.0 TB Volume”

Error mounting /dev/sdd1 at /media/a4090/disk: Command-line `mount -t "ufs" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdd1" "/media/a4090/disk"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so



At this point I entered commands to mount UFS manually (using this as a reference http://askubuntu.com/questions/85154/mount-ufs-filesystem )
This is the output from the CLI:

Code: 
a4090@x785:~$ sudo modprobe ufs
[sudo] password for aaa:
a4090@x785:~$ mkdir ~/ufs_mount
a4090@x785:~$ sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdd1 /home/aaa/ufs_mount
a4090@x785:~$

After these manipulations I go to the file manager that now sees the volume in question as mounted, but when I click on it I get the following popup error:

Code: 
 This location could not be displayed.

You do not have the permissions necessary to view the contents of “ufs_mount”.




In the file manager, when I navigate to /home/aaa/ufs_mount (with a mouse, of course) I am able to open the folder with no errors, but there are no visible files within it.


(Same simptoms in both Ubuntu and Debian)
 
Code: 
$ sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdd1 /home/aaa/ufs_mount

What does mount show after you issued the above command?
 
After restarting I've issued the command:

(note the sdd1 changed to sdb1)


Code: 
aaa@x785:~$ sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdb1 /home/aaa/ufs_mount

Login as root. Then quiry the mount directory from the console. You can use sudo also. I mean, if you haven't already tried this.
 
$ su
:
# ls -la $PATH_TO_UFS2_MOUNT <</home/aaa/ufsmount in your case>>
$OUTPUT

Those commands.
