Expand a Volume on VPS Cloud

This guide explains how to increase the storage volume of your VPS Cloud once the offer change has been made.

Preamble

• By default, the VPS Cloud comes with two volumes:
  • 1 volume for the operating system of your choice (/dev/vda).
  • 1 volume for storing your data (/dev/vdb), this is the one that will be increased.
• Note: depending on the installed operating system, the system volume may be named /dev/sda, /dev/sda1 or /dev/vda; the same applies to the data volume /dev/sdb, /dev/sdb2 or /dev/vdb … It is therefore necessary to replace these indications with those corresponding to your situation.

SSH commands to increase storage volume

If you choose **XFS**, for example, it is necessary to install the appropriate tools (if they are not already present):

sudo apt install xfsprogs

Then increase the volume with the following SSH commands:

sudo xfs_grow /dev/vdb

And if you choose EXT4:

sudo resize2fs /dev/vdb

Expanding the volume after increasing the storage volume

Two scenarios may arise once you have extended the storage volume of your Linux server. Note that no data is deleted when increasing the space via the VPS plan change.

First scenario

In the case where the entire volume is used without partitioning, it is not necessary to perform a resizepart, since there is no partition.

sudo umount /dev/vdb
sudo fsck.ext4 -f /dev/vdb
sudo resize2fs /dev/vdb

Second scenario

In the case of a volume that contains a partition (/dev/vdb1), you must first stop the processes that use this volume and then unmount the partition.

sudo umount /dev/vdb1

Next, you need to increase the partition size with parted, which has the resizepart command, unlike fdisk.

sudo parted /dev/vdb
GNU Parted 3.2
Using /dev/vdb

(parted) quit
sudo fsck.ext4 -f /dev/vdb1
sudo resize2fs /dev/vdb1

And the System volume?

It is not possible to increase the size of the system volume.

For Linux, Infomaniak provides 20 GB, sufficient for any Linux distribution.

For Windows, Infomaniak provides 100 GB on the C drive, which is sufficient for Windows. Applications must be installed on the D drive. If you have 50 GB, you can request 100 GB (contact Infomaniak support specifying a time slot for the operation as there will be a few minutes of interruption to expect).
