Ubuntu – Error trying to mount FreeBSD/UFS partition from FreeNAS

mountnas

I get this strange error trying to mount UFS partition.

   sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdb2 /home/tim/ufs_mount
   mount: wrong fs type, bad option, bad superblock on /dev/sdb2,
          missing codepage or helper program, or other error
          In some cases useful info is found in syslog - try
          dmesg | tail  or so

I'm a Ubuntu newbie and just switched from FreeNAS.

tim@T3:~$ sudo fdisk -l

  • You need to get the bsd partition, that fdisk -l cant show you.

    First:

    $ dmesg|grep bsd
    
    [    3.467958]  sde1: <bsd:bad subpartition - ignored
    [    3.467959]  sde2: <bsd: sde5 >
    

    Look after a partion, in this case sde5 seemed to be the one fore me.

    Then:

    $ sudo mount -t ufs -r -o ufstype=ufs2 /dev/sde5 ~/freebsd
