Expand metadata storage

Expand metadata storage by increasing the size of existing metadata disks.

Prerequisites

It is recommended that you expand metadata storage by adding new metadata disks. When the total number of metadata disks reaches its limit, you can expand metadata storage by increasing the size of existing metadata disks. Shrinking disks size is not supported.

  • Before expanding metadata storage, disable the file system.
  • You cannot expand the first metadata disk.
  • Observe the recommended increment size of 1 TiB.

Steps

  1. Power off the DDVE by using the CLI: 
    #system poweroff
  2. Log in to the GCP web console, and select Compute Engine > VM Instances.
  3. On VM Instance details page, go to Additional disks, and select the metadata disk that you plan to expand.
    NOTE You cannot expand the first metadata disk.
  4. To increase the size of the selected metadata disk, click the EDIT button.
  5. To increase the size of other metadata disks, repeat step 3 and step 4.
  6. Start the DDVE.
  7. To confirm the disk size change, use the Disk show hardware or Storage show all command.
  8. Disable the file system with the filesys disable command.
  9. Expand metadata storage with the filesys expand command.
  10. Enable file system with the filesys enable command, and check file system status with filesys status command.
  11. To confirm the metadata storage expansion, use the filesys show space tier active local-metadata command.
