fdisk
โดยทั่วไปยังคงพร้อมใช้งานและสามารถทำได้ถ้าพาร์ติชันเป็นพาร์ติชันสุดท้ายและจุดเริ่มต้นของพาร์ติชันไม่ได้ย้าย
อย่างไรก็ตามนี่เป็นการผ่าตัดที่อันตรายที่ควรทำด้วยความระมัดระวัง ทำการสำรองข้อมูล!

The partition table has been altered.
Calling ioctl() to re-read partition table.
Re-reading the partition table failed.: Device or resource busy
The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).
