So, if I use Method I, as you specified in the book, can I then move those particular partitions (/, /usr, /var) around without worrying about the original unix partition layout (offsets etc)? So, the original /, /usr, /var sizes and offsets won't limit the location of the /dev/vinum/root, /dev/vinum/usr, /dev/vinum/var? > > Method II.

Ok, Method I is the best way to bootstrap the whole process, and once you have a base setup running on vinum you still have the flexibility of Method II anyway. If that's right, then Method I is definitely the way to go. > Greg For the mirroring case, should the swap partitions be mirrored too? Was under the impression that swap might be handled by a completely separate process and that there was no need for vinum to have to handle any swap stuff.
