I'm pretty sure there is a command, I came across it studying for the
RHCE, and said "must remember that". Didn't. :-(
Someone commented on upgrading your fdisk. From man fdisk (in Ubuntu
Warty):
A sync() and a BLKRRPART ioctl() (reread partition table from
disk) are performed before exiting when the partition table
has been updated. Long ago it used to be necessary to reboot
after the use of fdisk. I do not think this is the case
anymore ...
You might also try (untested by me):
blockdev --rereadpt
HTH and long live the uptime,
Tony
