Linux中使用parted分區工具進行GPT分區示例

使用parted和gdisk工具對硬碟進行GPT分區的最後效果差不多。

如果是固态硬碟，使用parted對硬碟分區預設會進行4K對齊。

但是使用parted分區，是直接修改分區表，實際環境中配置容錯率很低。

基本配置舉例：

配置前，使用fdisk -l 确認你的linux系統有一塊空的硬碟

(parted) mklabel gpt  # 使用GPT分區，支援2T以上的硬碟
Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue?
Yes/No? yes  # 輸入yes

(parted) mkpart  # 該指令進行分區
Partition name?  []?  # 設定分區名字
File system type?  [ext2]? xfs  # 設定分區類型
Start? 1  # 1表示從最開始分區，也可以用百分比表示，比如Start? 0% , End? 50%
End? -1   # -1表示到磁盤末尾；也可以分成多個磁盤，寫要配置設定的大小

# 如果想分兩個分區，大小均分，可以這樣寫
# Start? 1
# End? 50%

# 另一個分區
# Start? 50%
# End? 100%

(parted) print  # 檢查

# 下面是删除分區示例

使用parted分完區後，可以直接格式化

[[email protected] ~]# mkfs.xfs -f /dev/sdb1
meta-data=/dev/sdb1              isize=256    agcount=4, agsize=13107072 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=0        finobt=0
data     =                       bsize=4096   blocks=52428288, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=0
log      =internal log           bsize=4096   blocks=25599, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0
           

然後/etc/fstab進行挂載

[[email protected] ~]# vim /etc/fstab
