linux檢視硬碟分區UUID

UUID是什麼？可以大緻了解為分區的表述符。

指令：

1、blkid

#blkid

/dev/block/253:1: UUID="0559cb97-8399-4656-a928-2d2211064424" TYPE="ext4" 

/dev/vdb: LABEL="gpt" UUID="a7338f0c-2e18-4ffb-a31b-199934d70118" TYPE="ext4" 

/dev/vdc: LABEL="gpt" UUID="58206cb6-c35c-456c-a5ad-210fc7f20aec" TYPE="ext4" 

2、ls -l /dev/disk/by-uuid/

#ls -l /dev/disk/by-uuid/

3、ls -l /dev/disk/by-id/

/dev/disk目錄下有幾個目錄，如：by-id、by-label、by-uuid。

 by-id     ：硬碟分區的永久性符号連結)

 by-label   ：按卷辨別别的硬碟分區，常用于挂載)

 by-path   ：硬碟分區的節點連結

by-uuid   ：按UUID識别的硬碟分區，常用于挂載
