[OS:N:] Adding a partition

["Stuart D. Gathman" <stuart bmsi com>]

At least in 2.4, fdisk changes are not seen by the kernel until the disk
is closed and reopened.  This means that all existing filesystems on the
disk must be unmounted.  With most setups, in practice this means that you
cannot repartition without a reboot.  I would guess that you haven't
rebooted since running fdisk, and that sda1 and sda2 are still in use.

I would complain (about not being able to add a partition without a reboot),
but using LVM instead of partitions lets you do that and more.
