[CentOS] Re: Anaconda doesn't support raid10

[Russ]

I'm not sure what you mean by "get real old stuff for your controller".  The controller is brand new, although the pc is a few years old.  The controller is si3114 based.  What's so quirky about it vs si3124?

Here's the way I plan to set things up.  Please let me know if this is worse then what you suggest.  

4 partitions per drive
1st partition - 200 mb
2nd partition - 250 mb
3rd partition - 5gb
4th partition - 745gb

Md0 raid 1 with 2 spares - 1st partition of all drives - /boot
Md1 raid0 - 2nd partition of all drives - swap
Md2 raid6 - 3rd partition of all drives - /

After install create
Md10 raid10 - 4th partition of all drives - /data

What advantages, if any, would lvm have over this set up?

If this is a file server too, may I suggest that you keep system stuff 
separate from your data like Les says he does? Did you have to get real 
old stuff for your add-on 'raid' controller? A newer and less quirky 
si3124 based controller cannot be much more expensive than what you have 
given that you have a four port card.

Please put boot and /tmp (maybe 512MB/1GB each) on its own mirrored 
partition, then make two nice big mirrors from the rest and use lvm to 
stripe them. That way, you don't have to make a lot of partitions to 
balance usage to get a four big partitions to get your 'raid10' array. 
anaconda supports this kind of configuration easily and you can also 
create the volumes for swap, /, whatever_you_fancy_partition, maybe 
/opt, /usr/local, /home with anaconda.
