6.6. 列出持久性命名属性

流程

• 要列出 UUID 和 Label 属性，请使用 lsblk 工具：

  $ lsblk --fs storage-device

  Copy to Clipboard Toggle word wrap

  例如，查看文件系统的 UUID 标签：

  $ lsblk --fs /dev/sda1
  
  NAME FSTYPE LABEL UUID                                 MOUNTPOINT
  sda1 xfs    Boot  afa5d5e3-9050-48c3-acc1-bb30095f3dc4 /boot

  Copy to Clipboard Toggle word wrap

• 要列出 PARTUUID 属性，请使用 lsblk 工具以及 --output +PARTUUID 选项：

  $ lsblk --output +PARTUUID

  Copy to Clipboard Toggle word wrap

  例如，查看分区的 PARTUUID 属性：

  $ lsblk --output +PARTUUID /dev/sda1
  
  NAME MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT PARTUUID
  sda1   8:1    0  512M  0 part /boot      4cd1448a-01

• 要列出 WWID 属性，请检查 /dev/disk/by-id/ 目录中符号链接的目标。

  例如，查看系统中所有存储设备的 WWID：

  $ file /dev/disk/by-id/*
  
  /dev/disk/by-id/ata-QEMU_HARDDISK_QM00001
  symbolic link to ../../sda
  /dev/disk/by-id/ata-QEMU_HARDDISK_QM00001-part1
  symbolic link to ../../sda1
  /dev/disk/by-id/ata-QEMU_HARDDISK_QM00001-part2
  symbolic link to ../../sda2
  /dev/disk/by-id/dm-name-rhel_rhel8-root
  symbolic link to ../../dm-0
  /dev/disk/by-id/dm-name-rhel_rhel8-swap
  symbolic link to ../../dm-1
  /dev/disk/by-id/dm-uuid-LVM-QIWtEHtXGobe5bewlIUDivKOz5ofkgFhP0RMFsNyySVihqEl2cWWbR7MjXJolD6g
  symbolic link to ../../dm-1
  /dev/disk/by-id/dm-uuid-LVM-QIWtEHtXGobe5bewlIUDivKOz5ofkgFhXqH2M45hD2H9nAf2qfWSrlRLhzfMyOKd
  symbolic link to ../../dm-0
  /dev/disk/by-id/lvm-pv-uuid-atlr2Y-vuMo-ueoH-CpMG-4JuH-AhEF-wu4QQm
  symbolic link to ../../sda2
