q: command not found

ubuntu@ubuntu:~$ sudo partprobe

suError: Error informing the kernel about modifications to partition /dev/sr0p1 -- Invalid argument. This means Linux won't know about any changes you made to /dev/sr0p1 until you reboot -- so you shouldn't mount it or use it in any way before rebooting.

Error: Failed to add partition 1 (Invalid argument)

fdisk -s <partition> give partition size(s) in blocks

 

Options:

-b <size> sector size (512, 1024, 2048 or 4096)

-c[=<mode>] compatible mode: 'dos' or 'nondos' (default)

-h print this help text

-u[=<unit>] display units: 'cylinders' or 'sectors' (default)
