Only report what would be done
Only modify partition table if the given partition would grow more than COUNT sectors (512 bytes). The default value is 20480 indicating that no change will be made unless more than 10M of space would be gained.
Give more information to stderr.


The device or disk image to operate on
The number of the partition to resize (counting from 1)


Rewrite a partition table in a disk or disk image so that the given partition takes up as much space as it can. After running, the partition will end at the end of the disk, or at the beginning of the next partition.


growpart /dev/sda 1

growpart my.image 2


The exit status is 0 if the partition was successfully grown or if --dry-run was specified and it could be grown. The exit status is 1 if the partition could not be grown due to lack of available space. The exit status is 2 if an error occurred.
