Re: Raw Partition layout on Linux

I believe raw disk can be created but it wasn't standard, maybe in 2.4 when it's ready. If I were you I would investigate using LVM for linux bung your disks in a volume group and carve them into 2 gig chunks, I believe raw lvm devices are possible to. I've never done the above, by the way, but am thinking about it. cheers mja In article <m3hf7eo28v.fsf@yakisoba.forte-intl.com>, Ronald Cole <ronald@forte-intl.com> wrote: > jrgjr@my-deja.com writes: > > Nope.
