FreeBSD disk partitioning

Michael W Lucas is back again with this blog about FreeBSD disk partitioning.

The FreeBSD kernel understands several different disk partitioning schemes, including the traditional x86 MBR (slices), the current GPT, BSD disklabels, as well as schemes from Apple, Microsoft, NEC (PC98), and Sun. The gpart(8) tool is intended as a generic interface that lets you manage disk partitioning in all of these schemes, and abstract away all of the innards in favor of saying “Use X partitioning system on this disk, and put these partitions on it.” It’s a great goal.

FreeBSD storage, and computing storage in general, is in a transitory state today. The older tools, fdisk and bsdlabel, aren’t exactly deprecated but they are not encouraged. x86 hardware is moving towards GPT, but there’s an awful lot of MBR-only gear deployed. Disks themselves are moving from the long-standing 512B sector size to 4KB, eight times larger.
