growpart /dev/sdX [n]
Example
growpart -N /path/to/disk.img [n]
说明
growpart extends a partition to fill available free space following it on a disk. It is commonly used after enlarging a virtual disk or cloud volume to make the added space available to the partition. The tool works with both physical disks (like /dev/sda) and disk image files. It automatically handles partition table updates for both MBR and GPT partition schemes. After growing a partition, you typically need to resize the filesystem within it using tools like resize2fs (ext4), xfs_growfs (XFS), or btrfs filesystem resize (Btrfs).
