With the LVM this has changed. AFAIR only a small boot area (/stand) or for other configurations the root file system is required to be in hfs format and must be contiguous. There should be a pointer towards it somewhere in the LVM data structures. All other file systems can be VxFS. > A logical volume might span one disk, or multiple disks, or stripe > across all the disks.. and you can extend the filesystems later, and > they don't have to be contiguous.
