Didn't know it could be done while mounted.  Thanks for that.

In general, if you have primary partitions on the drive and you modify
those primary partitions, the kernel can reload the new partition table
without a reboot (that's the ioctl call as fdisk exits).  If you have
any logical partitions on the drive, the kernel will not see those and
you'll need a reboot.
