I think his confusion stems from the fact that most (all?) hardware raid controllers only allow you to use the whole disk for a raid volume, not parts of it, and a disk can only be in a single raid volume (with the exception of a global hotspare).

That sounds too scary. Well, I may be wrong or may be using the wrong terminology, but on several occasions I did create several RAID 0 an 1 partitions on two disks. I would create a RAID 0 partition where I needed a boost in performance, a RAID 1 partition where I needed more security. What do you say is wrong with that? Why is it wrong to create RAID devices, even of different types, with only two disks? I don't understand what you mean: virtual RAID sets? Of course they are virtual, but they are made of real disk space, not the entire disks but adequate parts of the disks. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
