Re: RAID for large disks

["Mag Gam" <magawake@gmail.com>]

Thanks thats the exact same question I have.

Does this page, http://www.redhat.com/archives/linux-lvm/2006-October/msg00014.html, hold any validity? The poster makes a good argument, but by seeing Damon's response it makes no sense to go thru the trouble. I would be willing to try this if I get some assistance...

I think you are confusing stripe and stride (and others may not
realize it's still a stripe in RAID5 even though it's not a mirror).

This email seems to be apropos -

but I dont' have any advice for you.
