Example
addpart [device] [partition] [start] [length]
说明
addpart is a simple wrapper around the "add partition" ioctl that notifies the Linux kernel about a partition that exists on disk but was not detected automatically. This is useful when partition tables are modified while the disk is in use, or when the kernel's partition scanning missed an entry during boot. The command only updates the kernel's in-memory partition table; it does not create or modify the actual partition table on disk.
参数
- device
- The block device containing the partition (e.g., /dev/sda)
- partition
- The partition number to add
- start
- The starting sector of the partition
- length
- The length of the partition in sectors
