Guide to Expanding Partition Space on a Cloud Server

Before adding a disk to the operating system, you must create it in your server management panel.

Steps to Expand a Disk in the Management Panel

Operating System Disk

Expanding the Operating System Disk

1. Log in to the Control Panel:
   • Sign in to your account and go to the Cloud Server section.
2. In the Server tab, access your server management panel.
3. In your server management page, click on Resource Plan.
4. Then, increase the size of your operating system disk.

caution

Please note that you cannot reduce the allocated disk size.

Non-Operating System Disk

Expanding a Non-Operating System Disk

1. Log in to the Control Panel:
   • Sign in to your account and go to the Cloud Server section in the control panel.
2. Go to the Disk section.
3. Click on the desired disk and then select Edit.
4. Enter the following details:
   • Disk Size: Use the slider to set the disk size (in this example, 1 GB is selected).
5. Click the Edit button.
6. Your disk has now been expanded.

caution

Please note that you cannot reduce the allocated disk size.

Steps to Expand Partition Space

1. Identifying New Space in the Operating System

After increasing the disk size, the operating system must recognize the new space:

Ubuntu/Debian

sudo fdisk -l

RockyLinux/AlmaLinux

sudo fdisk -l

FreeBSD

sudo gpart show

This command lists the existing disks and partitions. The new space should appear as unallocated.

2. Extending the Existing Partition

To expand the existing partition, execute the following commands:

Ubuntu/Debian

sudo fdisk /dev/vdX

Follow these steps after executing fdisk:

1. Enter p to list the current partitions.
2. Note the partition number you want to extend.
3. Enter d and select the partition number to delete it.
4. Enter n to create a new partition.
5. Specify the partition type (usually primary) and select the same partition number as before.
6. Enter the Start sector exactly as the previous value.
7. For the End sector, select the suggested value (maximum size) to utilize all the new space.
8. Save changes and exit with w.

RockyLinux/AlmaLinux

sudo fdisk /dev/vdX

Follow the same steps as in Ubuntu/Debian:

1. Enter p to list current partitions.
2. Note the partition number to extend.
3. Enter d and select the partition to delete it.
4. Enter n to create a new partition.
5. Choose the partition type (primary) and select the same partition number as before.
6. Enter the Start sector exactly as before.
7. For the End sector, select the suggested maximum value.
8. Save and exit with w.

FreeBSD

sudo gpart resize -i 1 vtbdX

In this example, /dev/vdX or vtbdX is the disk, and 1 is the partition number.

3. Expanding the Filesystem

After expanding the partition, extend the filesystem:

ext4 Filesystem

sudo resize2fs /dev/vdX1

XFS Filesystem

sudo xfs_growfs /

UFS Filesystem (FreeBSD)

sudo growfs /dev/vtbdXp1

Note: For the XFS filesystem, xfs_growfs must be executed on the mount point.

4. Verifying Configuration

To ensure proper configuration, check the settings:

Linux (Ubuntu/Debian/RockyLinux/AlmaLinux)

df -h

FreeBSD

df -h

Important Notes:

• Always back up your data before making any partition changes.
• Carefully execute commands according to your disk and partition structure.
• For more details, refer to your Linux distribution's official documentation.
