Thought I would ask this here rather than in the microserver thread.

I plan to get 4 x 2Tb drives and maid a RAID5 array within Ubuntu, but I also need to partition of about 250Gb separately.

Do you create the array, then create partitions on the array? Or is the array the partition?

Ok I have ubuntu installed on a separate 160Gb HDD, the 2Tb drives are yet to arrive.

So not sure how those instructions relate, damn this would be easier if i had the bloody disks lol

The key thing here is the raid controller you are using ?

If it is an ICHxR then it is a "software" raid controller (even in Windows), if you have a proper raid controller then you can run hardware raid with no issues (Linux has drivers for pretty well all hardware raid controllers).

I won't be using a raid controller just doing it in software will be using HP microserber
 
Because a simple thing as a driver update can loose your array, i'm not against software raid in a test environment and to a certain extent Raid1. But Raid0,5 should be a no no with any data you value.
It simple doesn't bring any of the benefits of using raid in the first place.

Maybe, but in Linux the RAID array config/info is stored on the disks, so as long as your data array is separate to your install which is what I am doing, I can reinstall linux, rescan for the array and mount it.
