HowTo: Reload (re-read) Partition Table In Ubuntu Linux

How do I reload the partition table in Ubuntu Linux without rebooting the systems?

You need to install the parted package as follows
sudo apt-get update
sudo apt-get install parted

Once installed type the following command to re-read / reload the partition:
sudo partprobe
Finally, use mkfs.ext3 or mkfs.ext4 to create the file systems:
sudo mkfs.ext3 /dev/sdXY
Make sure you replace /dev/sdXY with actual device name and be careful do not type wrong device same. You may end up destroying working data. Please note that on server with RAID and SAS disk you may need to type the following command to rescan changes:
sudo echo 1 > /sys/block/sdd/device/rescan
sudo fdisk -l
sudo mkfs.ext3 /dev/sdXY

Again replace sdd with actual device name. Please note that above commands should work with all Linux distributions.
