I have 2 raid arrays.
raid 1, 17 GB
raid 5, 52 GB
Each array is on it's own channel, connected to a LSI megaraid 320-2x scsi raid controller.

I run Centos 4.3 and directadmin on the raid 1 array.

I want my databases and static files (images, html. php, asp etc.) on the raid 5 array. Do i have to mount my raid 5 array to /var and /home? Or just make a new directory and mount my raid 5 array to it, and configure mysql and directadmin to store the databases and static files in that directory?

If i just mount it to /var and /home, all data will be spread among the raid 5 AND raid 1 array right? Because /var and /home are originally mounted to the raid 1 array.

If you have any suggestions how i should do it, please let me know!
Thanks.

No, mounting your raid partition on /home or /var will hide the contents.
The mysql databases are located in /var/lib/mysql. You could mount a raid partition there.
There is mysql documentation in /usr/share/doc/packages/mysql/

A mention is made in the installation section about building mysql. One of the options is --with-raid. I haven't read up on this but it may be something to look at.

And what if i copy the var and home directories to my raid 5 array, and then mount it?
I have DirectAdmin installed, and it seems that it changed my directory structure, where all stuff is being stored.

Anyone? Need some help here.
