If you have a spare drive, the obvious thing to do is to migrate the entire installation to that drive. In this case you just need to create Vinum volumes of the appropriate size, then copy. Make sure to put a bootstrap on the drive (disklabel -B). When that's up and running, you can repartition the original drive and do whatever you want with it. > Filesystem 1K-blocks Used Avail Capacity Mounted on > /dev/ad0s1a 7225214 2207318 4439880 33% / > /dev/ad0s1f 14985070 268 13785998 0% /usr/home > /dev/ad0s1e 15483630 33702 14211238 0% /var > procfs 4 4 0 100% /proc > Swap is 768mb In this case, the output of disklabel would be more use. I'd expect to see something like this: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 8388608 0 4.2BSD 2048 16384 89 # (Cyl. 0 - 3328*) b: 1048576 8388608 swap # (Cyl. 3328*- 3744*) c: 26712000 0 unused 0 0 # (Cyl. 0 - 10599) e: 17274816 9437184 4.2BSD 2048 16384 89 # (Cyl. 3744*- 10599*) This gives the positions of the partitions as well as their size.
