I have no idea how your existing ATA100 controller compares to the TX2. You could check the specs at Promise's web site or send them e-mail if you really want to know. > Could I use 2 hard discs having different specification and capacity ? Probably. I haven't checked Linux's RAID implementation in detail, so I can't confirm what happens if you mix and fast and slow drive. You may limit your- self to the slowest drive speed. As for capacity, the software implemenation is by partition so you have to make sure that the 2 partitions you're mirroring are the same size. > Could you please explain a little bid in detail, to mirror first few > partitions on each hard disc ? How many hard disc you install ? 4 hard > discs to achieve RAID 0 + 1 ? I installed 2 hard disks, partitioned each and used RAID-1 for /, /boot, /usr, /home, and /var. I added swap partitions that aren't mirrored, and then had 2 spare 10GB partitions on each drive. I don't use RAID-0 - in most cases, you don't need (nor want) this. -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED] _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
