You can resize your disk following this guide or with the following command:

gcloud compute disks resize DISK_NAME --size DISK_SIZE

Or with the Console:

  1. Go to the Disks page to see a list of zonal persistent disks in your project.
  2. Click the name of the disk that you want to resize.
  3. On the disk details page, click Edit.
  4. In the Size field, enter the new size for your disk.
  5. Click Save to apply your changes to the disk.

After you resize the disk, you must resize the file system so that the operating system can access the additional space.

Note: Do not resize boot disks beyond 2 TB because this is the limit.
