Extend a Partition

Extend a disk partition after increasing disk size

After upgrading your VPS storage, you need to extend the partition to use the additional space.

Prerequisites

• A VPS with OnetSolutions
• Increased disk size (via upgrade)
• Root or sudo access

Always backup your data before modifying disk partitions.

Extension Steps

1. Identify disk and partition

   List available disks and partitions:

   lsblk
   

   Note the device name (e.g., /dev/vda) and partition number (e.g., 1 for /dev/vda1).

2. Extend the partition

   Use growpart to extend the partition:

   sudo growpart /dev/vda 1
   

   Replace /dev/vda and 1 with your actual device and partition number.

3. Verify partition extension

   Run lsblk again to confirm the partition shows the increased size.

4. Resize the filesystem

   Extend the filesystem to use the new space:

   sudo resize2fs /dev/vda1
   

   Replace /dev/vda1 with your actual partition.

5. Verify the changes

   Check disk space usage:

   df -h
   

   Your partition should now show the increased size.

Installing Required Tools

The growpart tool extends the partition, while resize2fs or xfs_growfs extends the filesystem to use the new space.

If growpart is not installed:

Debian/Ubuntu

sudo apt install cloud-guest-utils

CentOS/Rocky/Alma

sudo yum install cloud-utils-growpart

Filesystem Commands

ext4 filesystem

Most common Linux filesystem. Use resize2fs:

sudo resize2fs /dev/vda1

XFS filesystem

Default on CentOS/Rocky/Alma. Use xfs_growfs:

sudo xfs_growfs /dev/vda1

To check your filesystem type, run: df -Th
