Mounting Darwin UFS

As hadn’t found it easily online I will post it here for the search engines to pick up, I was using CentOS 6.2, although this should work for most Linux versions.

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

Install How To

  1. Download the latest elrepo-release rpm from
  2. Install elrepo-release rpm:
    # rpm -Uvh elrepo-release*rpm
  3. Install kmod-ufs rpm package:
    # yum install kmod-ufs
  4. Mount with UFS type openstep
    # mount -t ufs -o ro,ufstype=openstep /dev/sdd1 /media/sdd1/

If you don’t have a Darmin UFS partition the other ufstypes you might want to try are:
old format of ufs
default value, supported os read-only

used in FreeBSD, NetBSD, OpenBSD
supported os read-write

used in FreeBSD 5.x
