Ubuntu Desktop RAID5 Best Practices
Posted on 2011-03-09
Hey there Experts,
I'm getting ready to build an Ubuntu Desktop box that I'll be using for a virtual machine server using Ubuntu desktop and virtualbox. I would like to create a RAID array to allow for hard drive fault tolerance but I'm a little shaky on the details of this, especially in Ubuntu.
I have 3 500GB SATA drives that I would like to use for the array. I also have a 250GB SATA drive which came with my server. I think I would like RAID5.
I guess the most basic question is this:
Should I add the 250GB drive, install Ubuntu on it, and then create my array from the three 500GB drives to hold my VMs? or
Should I just leave the 250GB drive out of the picture and install Ubuntu and my array on the three 500GB drives.
It seems counter-intuitive to me to use the 250GB for the OS but I have seen this setup referenced on the web.
Anyway, any help you can give will be greatly appreciated.
PS - there is no hardware RAID controller and the budget is shoestring so we'll be sticking w/ software RAID.
