通过UUID挂载Linux文件系统

通过UUID在fstab中挂载分区

  

通常情况，Linux的/etc/fstab文件可能有如下内容：

# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point>   <type>  <options>       <dump> <pass> proc            /proc           proc    nodev,noexec,nosuid 0       0 # / was on /dev/sda1 during installation UUID=8f21495f-bd94-4a88-b433-e52b71475941     /               ext4   errors=remount-ro 0       1 # swap was on /dev/sda2 during installation UUID=c16a9b20-d020-4741-a1b8-702ba18e82de     none            swap   sw                0       0

查看UUID的命令: blkid

[root@bigops lib]# blkid
