Did you try to boot from the livecd, or another boot cd, and see if
you can even mount your JFS partition?
Jim
Yes I have. It mounts fine when using the livecd to boot from. I can
read/write to it no problem, and all the file structure is there.
I've had a look at the bootlog with dmesg, and I'm now thinking that
the installed kernel doesn't have JFS modules/support in it......the
boot identifies the partitions (hda1, hda2 etc), but then it tries to
mount hda2 with almost every fs APART from my beloved jfs. It's tried
Reiser, XFS, ext2, ext3, vfs - everything but jfs.
