Resizing raids would be really cool...
Andrew Clausen <[EMAIL PROTECTED]> is writting a program called
parted
that can do similar things to what partition magic does.
Parted is suppsed to be a frontend to the fat resizer (also done by him) and
extresize which has passed v1 now.
It would be great to see raid support for a program such as this.
Ive been thinking i would like to try and hack grub or lilo to recognise
raid partitions, im not sure how dificult it would be, but its a shame that
the kernel supports boot from striped raid but no bootloaders do.
