Extend Volume

After creating a volume, you may need to extend its size to accommodate growing data needs. This guide will help you extend a volume in Vietnix Cloud.

Prerequisites​

Steps to Extend Volume​

  1. Navigate to the Compute section and select Volumes. Navigate to Volumes
  2. Find the volume you want to extend and click on it. Select Volume
  3. At properties section, click the 🖊 icon at the Size field.
  4. In the Size field, enter the new size for the volume (e.g., 100GiB). New Size

    Note: Make sure the new size is larger than the current size.

  5. Click the ✔ button to apply the changes.
Important

Extending a volume does not automatically resize the filesystem. After extending the volume, you need to resize the filesystem on your instance to utilize the new space.

Note

After extending the volume, you may restart for auto allocation of the new size.

Resize Filesystem​

After extending the volume, you need to resize the filesystem on your instance to utilize the new space. The steps to resize the filesystem depend on the operating system and filesystem type.

For Linux Instances​

  1. SSH into your instance.

  2. Use the lsblk command to list the block devices and identify the extended volume

    lsblk

  3. Use the growpart command to extend the partition:

    sudo growpart /dev/sdX N

    Replace /dev/sdX with the actual device name of the volume and N with the partition number.

  4. Use the appropriate command to resize the filesystem based on the filesystem type:

    sudo resize2fs /dev/sdX

    Replace /dev/sdX with the actual device name of the extended volume and /mount/point with the actual mount point of the filesystem.

  5. Verify the new size using the df -h command:

    df -h
