UFS support needed

UFS support (both RO and RW) appears to have been removed from the kernel (at least it is not shown in /proc/filesystems) and attempts to mount using -t ufs do not work:

[dalbert@deforest ~]$ sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdb1 /mnt/hd21
mount: unknown filesystem type 'ufs'

I need to access data saved on a FreeBSD partition (UFS2)...is there any way to do this?
Any help would be much appreciated!

Re: UFS support needed

Unfortunately that topic is out of date (last post was 2007).  UFS support appears to have been removed entirely (including read-only).  I'm trying to find out if there is any way I can access an old FreeBSD UFS partition on a server that I moved to ArchLinux; it used to work, but at some point, even RO access appears to have been removed from Arch.

Re: UFS support needed

 $ grep UFS_FS /var/abs/core/linux/config*
/var/abs/core/linux/config:CONFIG_UFS_FS=m
/var/abs/core/linux/config:# CONFIG_UFS_FS_WRITE is not set
/var/abs/core/linux/config.x86_64:CONFIG_UFS_FS=m
/var/abs/core/linux/config.x86_64:# CONFIG_UFS_FS_WRITE is not set

modprobe ufs?

Re: UFS support needed

It turns out I needed to upgrade the kernel; this server was running 4.2.x (from October 2015) which did not include support for the ufs filesystem.  upgrading to 4.5.4-1 fixed the problem.  Thanks for the responses!
