I have installed a linux distro on a partition of my machine (latest Mandriva i686, default installation). I only need it to use a piece of software for Nikon Coolscan IV film scanner (yes, sane works, but a cheap commercial package called vuescan has better interface and uses some hardware features like infrared channel that sane does not support, at least in current stable version). Now I would like to mount ext3 partition from FreeBSD at least for reading, or vice versa, UFS2 from linux for writing. With kernel option EXT2FS, I can $ mount -t etx2fs /dev/ad12s7 /linux but then if I do $ ls /linux I get a 'Bad file descriptor' for directory /linux. e2fsprogs are installed, and fsck.ext2 or fsck.ext3 think well of the partition. Also, df seems to show it correctly, with size and free space. I have FreeBSD 7.0 for amd64, Linux is 32-bit version. Also the partition is 'extended', i.e. fdisk on FreeBSD shows a DOS partition, but linux's fdisk shows a couple of ext3 partitions. However, /dev/ad12s7 does correspond to the correct linux partition and, when mounted, df shows the right size and utilization. Any advice how to share a partition between these 2 systems? I only want to use linux to scan the film and store the pictures on disk, then boot into FreeBSD where I spend most of my life as a user. I feel more comfortable pulling from FreeBSD rather than pushing to it because (1) it is easier for me to recompile FreeBSD kernel or install packages if necessary, and (2) I would mind much less a corruption on the linux partition than on UFS; I can simply reinstall the default installation for Linux, but FreeBSD has important data and is finely tuned for me over the years.
