HowTo : Remount /etc/fstab Without Reboot in Linux

The configuration file /etc/fstab contains the necessary information to automate the process of mounting partitions.

You would normally have to reboot your Linux system, after editing this file.

There is a simple way which will remount all the partitions from your /etc/fstab file without restarting the system.

Run the following command as root:

# mount -a

This simple command causes all filesystems mentioned in /etc/fstab to be remounted, except the partitions with noauto option.
