automount a partition on linux

Partitions are not auto-mounted at boot time unless they are specified in /etc/fstab, this guide walks you through the process

Identify the block devices and their uuid (Universally unique identifier) from blkid, lsblk commands.

#lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 596.2G 0 disk
├─sda1 8:1 0 2G 0 part /boot
├─sda2 8:2 0 2G 0 part [SWAP]
├─sda3 8:3 0 1K 0 part
├─sda4 8:4 0 443.4G 0 part /run/media/cipher/e9480814-7c11-4ed1-956a-ab46610c5079

#blkid

/dev/sda2: UUID="6b659d6e-f7ee-4a59-a552-05164ad36a06" TYPE="swap" PARTUUID="fc396355-02"
/dev/sda4: UUID="e9480814-7c11-4ed1-956a-ab46610c5079" TYPE="ext4" PARTUUID="fc396355-04"
/dev/sda5: UUID="9ffb470e-71af-4c1d-b76e-55f5e09a8890" TYPE="ext4" PARTUUID="fc396355-05"

add sda4 partition uuid in /etc/fstab

UUID=e9480814-7c11-4ed1-956a-ab46610c5079 /media/data ext4 defaults 0 0

before rebooting the server make sure you have entered correct entries in fstab to check this issue command

#mount -a
mount: /media/data: mount point does not exist.
lets fix the mount point
#sudo mkdir -p /media/data
#sudo mount -a
#echo $?
0

we have setup automounting of drive it can be tested with df command.
