Linux RAID can already deal with such a problem IIRC but if the
filesystem superblock is missing or directory entries, you ain't going
no where. This kind of feature would require filesystem knowledge of
where the RAID split the device and would be better suited to a FS
like BTRFS which mirror superblock and metadata without any Linux
RAID.
Hi Jérôme
Thanks for the reply. I though BTRFS would be a good option as well,
but they don't seem to understand what I'm looking for :)
I have found a fuse base FS that seems to do this, so will play with that.
It's called http://romanrm.ru/en/mhddfs and seems to do what I need it
to do so will test :)
Thanks again for replying.

That looks like an interesting idea, and would be particularly useful if
you've already got several disks with filesystems and want to join them
together. However, I would never consider it for a /new/ setup. The
price of disk space is so low that I never again expect to set up a
computer without raid, unless it is a laptop with only space for one
disk, or a machine using some nameless inferior operating system that
doesn't support proper raid. Certainly if you are thinking of putting
three disks in a machine then raid10,far would be the natural choice, or
raid5 if you want a little more space for your pennies.
