Re: [gentoo-amd64] Upgrading to Raid

[Chris S]

Perhaps I should endeavour to answer a few other questions too..

No, however it's the same as other on-board raid controllers, they are 
sudo raid, in that they are Windows software based driver driven.
There was some support for them under 2.4, but not very well and 
certainly not for SATA - plus you want to use libata with built in sata 
support.

well you won't use the built in raid function so it doesn't matter. If 
you're talking which has better SATA support, I'd go for Promise.

>Is there a good Howto on migrating from a non Raid disk to Raid? I recall seeing one but can't find it now.

well if you're using linux software raid (lsr) then you can just tarball 
your whole system, build your raid and extract it, re-do your bootloader 
and you're done.
See forums.gentoo.org there are lots of posts re raid.

depends - can you afford downtime. if the answer is no, then go raid 1 
or higher.
if the answer is yes, then perhaps save your money, invest in a hdd and 
usb 2 / firewire drive and backup.
use rsync for incremental backups. u can also backup other pcs over the 
network.
this also gives you the ability to recover deleted files and versions, 
which raid does no (unless you setup your raid with CVS or subversion)

it's linux! so just boot to a livecd, tarball your entire drives and 
mounts, then extract to your new hdd setup.
