Re: Raid on Debian PPC
FWIW, I'm running a new style RAID0 with raidtools2 on a powerpc box. Took some
question-asking, and some other work, but it's runnung fine now. Used the
kernel-source-2.2.17.deb, applied the patch from ingo's site, ran the standard make
menuconfig,, make-kpkg, etc, and had no problems.
So it does work on a G3-all-in-one with a pair of 4-gig drives raided together.
