Unmanaged cloud server: increasing the data storage volume (Linux)

This guide explains how to increase the storage volume of your unmanaged Cloud server once you’ve switched offer.

SSH commands to increase the storage volume

If you choose e.g. XFS, it’s necessary to install the appropriate tools (if they’re not already present):

sudo apt install xfsprogs

Then expand 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 an expansion of the storage volume

There are two possible scenarios once you’ve expanded the storage volume of your Linux cloud server. Note that no data is deleted when increasing the disk space by changing the offer of your unmanaged cloud.

First scenario:

Where the entire volume is used without partition, it’s not necessary to do a resizepart, as there’s no partition.

sudo umount /devdb

sudo fsck.ext4 -f /dev/vdb

sudo resize2fs /dev/vdb

Second scenario:

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

sudo umount /dev/vdb1

You must then increase the size of the partition with parted which has the resizepart command, which is not the case with fdisk.

sudo umount /dev/db1

sudo parted /dev/vdb
