I am considering switching from FreeNAS to OpenFiler. One issue I see with this is that all the hard drives in my NAS are formatted to UFS. I tried but was unable to mount them in Fedora. Is there any way I can extract my data from the UFS hard drive without a FreeBSD OS?
Linux should be able to mount UFS easily as read-only. Try modprobe ufs2 if it has trouble mounting it.
What distro are you using?
UFS2 read only support is included into linux kernel since version 2.6.5. For example:
mount -t ufs -o ufstype=ufs2 -o ro /dev/hda3 /mnt/bsd/
You still need an extra HDD to copy data from UFS drive.
