i've been working on kenfs as we needed a way to have
automatic offsite backup. i am using aoe to do the offsite
bit so theoretically, one could have a kenfs with no disks.
i've also rewritten the marvell sata driver, added the intel
ahci driver, revamped mmu code. finally, i have a slight
change to the on-disk layout of the c part of the cw that
results in a 20x speed improvement. (this change can be
used on old fses if you dump and then recover using
the new code.) i've also implemented a new compile-time
option "fastworm" that inhibits copying from the worm to
the cache.
my current testing setup is
filsys main cp(a0)0.10{a1e99.0[e64.<0-3>]}
where
dev driver target
a? ahci
e99.0 aoe sr421
e64.? aoe pata shelf accessed over wireless link.
if you have any interest in this, please drop me a note
with the hardware you're using and i'll figure out how
to arrange access.
