Why Does My Vultr Compute Instance Show Almost 100% Disk Usage Even After Attaching a New Volume?

Updated on 15 September, 2025

Explains why adding a volume doesnt reduce root disk usage percentage as it creates separate storage rather than expanding the primary disk


Attaching a new volume to your instance does not expand the primary disk. Instead, it adds an additional storage device, mounted separately. The root disk remains the same size unless you change the instance plan to a larger plan.

To manage disk usage effectively:

  • Move large files (such as backups, media, or database dumps) to the newly attached volume.
  • Redirect system logs (e.g., /var/log/) to the volume to free up root disk space.
  • Use symbolic links or bind mounts to offload directories from the root partition.
