site_archiver@lists.apple.com Delivered-To: Darwin-dev@lists.apple.com John, I don't believe Linux is using lvm to do this. The raid is setup at install time. You use DiskDruid to first partition each disk into identically sized partitions and then create md devices which are set to a specific RAID type (RAID-1 for example) and contain particular partitions as the submirrors. I have also done something very similar under Solaris 9. One can take a Solaris 9 drive and replace the existing partitions with mirrors and submirrors on an existing installation. If I even had that level of flexiblity from MacOS X I would be happy. Jack _______________________________________________ Do not post admin requests to the list. They will be ignored.
