 Is it possible to add a harddrive to an existing Raid 0 Array? http://img120.imageshack.us/img120/5...cture13fm6.png I have an existing striped raid 0 setup with 2 x 500 GB hard drives. I just bought 2 more x 500 GB hard drives since i noticed HDD is a bottleneck for my 8 core system. my question is, can i add the 2 harddrives to my existing raid 0 partition ? (so i have one raid partition of 2 TB ) i tried this, but it didnt work Code: MacPro-PC:~ kronos$ diskutil listraid RAID SETS --------- =============================================================================== Name: Raid 0 Unique ID: 7CD5E941-6AA9-4F47-BE18-2183860B0596 Type: Stripe Status: Online Size: 999527743488 B Device Node: disk4 Apple RAID Version: 2 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 D8CB113A-4425-4E4D-AA1C-62118342CA89 Online 1 disk2s2 CC80544C-65A1-4F1D-A26C-F05E2EA92840 Online =============================================================================== Code: bash-3.2# diskutil addToRaid member disk0 /Volumes/Raid\ 0 Error adding the disk to the RAID: Could not modify RAID (-9960)  |

| The first thing I would try would be to boot from your Leopard install DVD and try to modify the RAID array that way, assuming that this is a software RAID array. I've never done this before with a boot volume, so this is only an educated suggestion.
