site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com Now that I have installed a second identical SATA drive I am interested in trying to get a multi-hfs RAID-1 mirror set up on my dual G5 under 10.3.5. I noticed that the DiskUtility program graphical interface won't work. While its help page on "Create a RAID set" indicates that either disks or volumes can be dragged to the RAID disks window to create a RAID in reality only disks can be used. Clicking on a volume from the disk removes the RAID tab in the DiskUtility window. My question is the following. It would seem my only remaining option is the diskutil command line program from Darwin. However the manpage for diskutil is unclear on the Create a RAID option. It says.... Create a RAID diskutil createRAID mirror MirrorDisk HFS+ disk disk2 and later says... DEVICES A device parameter to any of the above commands (except where explicitly defined otherwise) is any of the following The device node entry. Any entry of the form of /dev/disk*. ex. /dev/disk2 The disk identifier. Any entry of the form of disk*. ex. disk1s9 The volume mount point. Any entry of the form of /Volumes/Mountpoint. ex. /Volumes/Untitled which I would assume implies that I could in theory create two different RAID-1 partitions from a set of drives identically partitioned using commands like... diskutil createRAID mirror MirrorPanther HFS+ disk0s9 disk1s9 diskutil createRAID mirror MirrorTiger HFS+ disk0s10 disk1s10 where the s9 and s10 slices are existing partitions on the drives. Does anyone know if this has any chance of working? I would rather not waste my time if diskutil is known to not work in this manner.
