mounted UFS ro under linux but unable to read all folders


I have a low maybe medium experience with linux and no experience with unix and migrating from freenas to Ubuntu.
I'm trying to transfer 12 TB of data from UFS file system to ext3 file system under Ubuntu 10.04. The server has two 16TB virtual disks (raid10) and one 4TB virtual disk (raid10 too).

I mount the UFS virtual disk in Ubuntu with this command:

mount -r -t ufs -o ufstype=ufs2 /dev/sda1 /home/ufsdisk
I am able to read only 6TB of data instead of 12TB. The missing folders can be seen in midnight commander with a question mark in front of the folder (example: ?datafolder) and "Modify time" is 31 dec 1969.

Problematic folders are readable under free nas, I also fsckecked the virtual disk under freenas but mounted in linux I can only access 6TB.

Anyone else had similar problem?

yes! ufstype=ufs2 is the only ufstype option that works and lets me read the files except those folders with question mark.

Maybe there's a size limit for mounted UFS under linux?
