Subject: RAIT device driver feasibility
Date: Thu, 13 Jan 2005 16:42:44 +0100	[thread overview]
Message-ID: <41E696F4.3070700@linbox.com> (raw)

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,
