Linux of course should see one hard drive but at capacity of combined two. If I set up HW raid0 of two 20GB identical IDE hard drives Linux should see just one big 40GB hard drive. In my case it sees one 20GB hard drive. So I'm wonder how to correct this issue. Thanks for any thoughts.
I just looked up the raid levels: RAID 0 - reads and writes are done in parallel for performance increase RAID 1 - mirrors disks for redundancy and performance increase RAID 5 - build large disks and redundancy information So, it looks like Linux is right (as usual <grin>). N.B. at RAID 5, the parity information is distributed between all the disks, so you have to substact the size of a disk from the total size. It looks to me lvm - Logical Volume Manager - is more what you want. This creates a virtual disk and is a software sollution. Regards, Cees.
