It is certainly possible to create a partitionable RAID device from a loop device. Should be possible to use nbd as well, but I can't seem to get nbd to work on 2.6.21-rc (my working system runs 2.6.17). > > example: >> kpartx -a /dev/mapper/loop0 >> >> # ls /dev/mapper/loop0* >> /dev/mapper/loop0 /dev/mapper/loop0p1 /dev/mapper/loop0p2 >> /dev/mapper/loop0p3 > > i have seen a patch for loop.c doing this, though. search the archives > for this > > regards > roland > > > > > > On Thu, Mar 22, 2007 at 02:33:14PM +0000, Al Viro wrote: >> Correction: current ABI is crap.
