Migrating your notebook from a smaller to a larger disk

My colleague Christophe Pauliat - Principal Sales Consultant at Oracle - came up with a really nifty way to migrate his Solaris based notebook from a smaller disk to a larger one. I will copy his mail in verbatim here, because i think it’s extremely useful. It somewhat resembles the “workaround” for ZFS resizing, however Christophe does takes this significantly forward and does this for boot disks.

The autoexpand really does an large amount of the trick. The size of a mirrored pool is always the size of the smallest disk. When you have an 80 GB and a 500 GB disk, the size of the pool is 80 GB. Remove the 80 GB disk. The smallest disk is now 500 GB and the size of the pool is 500 GB now as well, as long as you’ve activated autoexpand.
