1、查看磁盘uuid
root@hos:~# blkid
/dev/nvme0n1: UUID="fbb59c47-281c-421b-ac33-e764bb0af516" TYPE="ext4"
/dev/nvme1n1: UUID="b37da31a-e416-4611-9239-238d7cf94673" TYPE="ext4"
/dev/nvme2n1: UUID="55aaf211-6963-42af-acad-0577b1bf7174" TYPE="ext4"
/dev/nvme3n1: UUID="750abcf1-197c-4c9f-91d8-f72d27766536" TYPE="ext4"
/dev/nvme4n1: UUID="3f8847a7-8d8a-493e-875c-99b4aa4c6a0a" TYPE="ext4"
/dev/nvme5n1: UUID="b43811df-662e-40d8-9faa-86dff9b16960" TYPE="ext4"
/dev/sdb1: UUID="572C-81CF" TYPE="vfat" PARTUUID="1283f450-ddba-49eb-bb36-d7da3937c10c"
/dev/sdb2: UUID="799c5e47-635b-42d5-a132-e1d6fcf73627" TYPE="ext4" PARTUUID="9184a5b4-c6d9-44c1-9f67-c6e6b01b0417"
/dev/sda: UUID="aa8cec0d-734d-445a-abdf-5411e067a1f3" TYPE="ext4"
/dev/loop0: TYPE="squashfs"
/dev/loop1: TYPE="squashfs"
root@hos:~# blkid /dev/nvme0n1 |awk '{printf $2}' |awk -F '\"' '{printf $2}'

2、查看所有磁盘
root@tidb3:~# lsblk

nvme4n1 259:4 0 1.8T 0 disk /nvme4

3、查看所有磁盘使用信息
root@tidb3:~# df -h
