How to permanently mount disk on Linux VPS

Januari 07, 2022

 If you want additional disk capacity on a VPS, usually the provider already provides it, you just need to order. After the additional disk is paid for, then mounting the additional disk to an existing server. In this tutorial I will show you how to permanently mount a disk on a Linux VPS.

The meaning here is permanent, when the server is rebooted, the disk (file system) is still detected (read) by the Linux system.

With root level, follow these steps:

1. Check file system

df -h

Output

Filesystem     1K-blocks     Used Available Use% Mounted on
udev             8153480        0   8153480   0% /dev
tmpfs            1637100     9504   1627596   1% /run
/dev/sda1      229698892 65885836 152075304  31% /
tmpfs            8185484        0   8185484   0% /dev/shm
tmpfs               5120        0      5120   0% /run/lock
tmpfs            8185484        0   8185484   0% /sys/fs/cgroup

In the description of the results of the disk file system check, only /dev/sda1 is detected ( just an example, because the name can be different, for example: /dev/sda2 ), even though there are other block devices, if you check with the command list block device: it lsblkwill be visible.

2. Check list block devices

lsblk

Result

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 223.6G  0 disk
|-sda0   8:1    0     1M  0 part
`-sda1   8:2    0 223.6G  0 part /
sdb      8:16   0 931.5G  0 disk
`-sdb1   8:17   0 931.5G  0 part
sr0     11:0    1  1024M  0 rom

Description of the results of check block devices, there is a partition on /dev/sdb1.

We can also confirm by checking block devices ID

blkid

Result

/dev/sda1: UUID="6adff89c-3178-4090-a98f-d16bc4704590" TYPE="ext4" PARTUUID="d9b163d1-0885-401d-a818-820c4drc2ea4"
/dev/sdb1: UUID="5a7db959-0c6d-4abe-9fa9-d6fad78d4880" TYPE="ext4" PARTUUID="8016131f-8c9d-4238-8a16-1266ad5era67"

Description of block devices and UUID will appear. We will use the value of this UUID to create a new row in the file system table or fstablater.

3. Mounting

I gave an example from the description of the additional disk output above, for example, the name of the block devices /dev/sdb1and I will mount it to a directory /backup(free directory name).

Now we will mount /dev/sdb1/to /backup. Follow these steps:

mount command /dev/sdb1/to/backup

mount /dev/sdb1 /backup

4. Mount permanen

After successfully mounting, so that it is permanent and can be read when the machine is restarted, register it to /etc/fstab

nano /etc/fstab

Add a new line according to the UUID of the partition.

UUID=5a7db959-0c6d-4abe-9fa9-d6fad78d4880 /backup ext4 defaults 0

5. Check the file system again

df -h

Make sure there is a list/dev/sdb1 /backup

Done, hopefully useful.
