# 創建分區表

# 警告數據將會被清空，輸入yes即可
# 創建一個主分區，並以2048扇區起始，使用全部容量（分區對齊）
mkpart primary 2048s 100%
# 分區沒有對齊，不推薦
mkpart primary ext4 0 -1
# 提示分區未對齊，輸入ignore忽略即可
Warning: The resulting partition is not properly aligned for best performance:
34s % 2048s != 0s
Ignore/Cancel? Ignore
# 查看分區對齊情況
align-check opt 1
# 如果輸出1 aligned則表示分區對齊
# 查看分區

- 刪除分區步驟：parted->查看分區->刪除分區
# 查看分區掛載情況
df -h
# 如果分區正在掛載，請先卸載
# 比如分區/dev/sdc1掛載在/data2上
umount /dev/sdc1
# 查看需要刪除的分區在哪個硬盤設備上
fdisk -l
# 比如要刪除/dev/sdc1這個分區，/dev/sdc1分區在/dev/sdc硬盤上
parted /dev/sdc

注意：
無論是創建/刪除分區，如果有掛載關係，都需要更新/etc/fstab文件！
