Probably the best way to go about that is to make dump(8)s of all filesyste= ms and save them on an external disk. The start a live-CD, and using gpart(8) delete the partitions you think are incorrectly sized, and create new ones with the correct sizes. If possible, leave the boot partition alone and use the same parition for the same filesystem as before. For sizes, I tend to use the following; / 500 MiB - 1 GiB /usr 20 GiB /var 3 GiB /tmp 20 GiB My /home partition gets the rest. Use newfs to create new filesystems, and then use restore(8) to put all data back. > P.S. sorry for me klutzy nomenclature, I am calling /dev/ada0p3 a > partition, when as you correctly observe it is a device .... my bad, & > maybe the source of confusion in my posts :-/ .... No, you are correct; ada0 is the device, ada0p3 is a parition. It is just t= hat gstripe is generally used on raw disks instead of partitions. (If you want = to tie partitions on one disk together it's probably better to re-partition). = But you can basically use any geom provider.
