Ouch! Talk about a performance bottleneck (using ATA drives as
"slaves"). And I don't want to even get started with the Promise
cards and drivers themselves.

Er, by this time, you could have spend a few buck more and gotten a
4-channel 3Ware Escalade 6000 or, better yet, 7000-series
(~$200-225). Then you'd have _real_, independent,
microcontroller-driven hardware RAID-5 from the system perspective.
Then "device" would then look like a single, "dumb" drive. Plus the
3Ware driver has been in the stock kernel since 2.2.15.

I thought the whole 2.4 kernel and software RAID-5 was not
recommended, no matter what fs you use?
