Hello,

I'd like to know if it's easy to write a RAID like device for tapes (RAIT)...
For block devices, hooks are present in the kernel code, but for char devices,
is there a way to implement a write function for example, which will write in
parallel to N /dev/stX tape devices ?

RAIT already exists in Amanda, in user space, but I'd like to see a generic
kernel RAIT driver which could be used by any backup program.

Cheers,
