Chapter 18. Persistently mounting file systems

1. The block device identified by a persistent attribute or a path in the /dev directory.
2. The directory where the device will be mounted.
3. The file system on the device.
4. Mount options for the file system, which includes the defaults option to mount the partition at boot time with default options. The mount option field also recognizes the systemd mount unit options in the x-systemd.option format.
5. Backup option for the dump utility.
6. Check order for the fsck utility.

Procedure

1. Find out the UUID attribute of the file system:

   $ lsblk --fs storage-device

   For example:

   Example 18.2. Viewing the UUID of a partition

   $ lsblk --fs /dev/sda1
   
   NAME FSTYPE LABEL UUID                                 MOUNTPOINT
   sda1 xfs    Boot  ea74bbec-536d-490c-b8d9-5b40bbd7545b /boot

2. If the mount point directory does not exist, create it:

   # mkdir --parents mount-point

3. As root, edit the /etc/fstab file and add a line for the file system, identified by the UUID.

   For example:

   Example 18.3. The /boot mount point in /etc/fstab

   UUID=ea74bbec-536d-490c-b8d9-5b40bbd7545b /boot xfs defaults 0 0

4. Regenerate mount units so that your system registers the new configuration:

   # systemctl daemon-reload

5. Try mounting the file system to verify that the configuration works:

   # mount mount-point
