Linux partprobe command
partprobe is a program that informs the operating system kernel of partition table changes, by requesting that the operating system re-read the partition table. For instance, if you create a new partition on one of your disks using parted, you should run partprobe afterwards to make the kernel aware of the new partition configuration.
partprobe [-d] [-s] [devices...]
|-d||Don't update the kernel.|
|-s||Show a summary of devices and their partitions.|
|-h||Show summary of options.|
|-v||Show version of program.|
Update the kernel's information about the current status of disk partitions, asking it to re-read the partition table.
