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.

  • Before expanding metadata storage, disable the file system.
  • You cannot expand the first metadata disk.
  • When expanding the size of an existing metadata disk, it is recommended to expand it in 1 TiB increments.
  • Shrinking the metadata disk is not supported.

Steps

  1. Shut down the DDVE instance by using the system system poweroff command from the CLI.
  2. Log in to the AWS web console.
    1. From the Volumes tab, select the metadata disk that you want to expand.
      NOTE The first metadata disk is not available for expansion.
    2. Click Actions > Modify Volume.
    3. Change the size of the metadata disk (for example, from 1024 TiB to 2048 TiB), and click Modify.
  3. To increase the size of other metadata disks, if required, repeat step 2.
  4. From the AWS web console, select the DDVE and start it.
  5. Disable the file system with the filesys disable command.
  6. Expand metadata storage with the filesys expand command.
  7. Enable the file system by using the filesys enable command.
  8. To confirm the metadata storage expansion, use the filesys show space tier active local-metadata command.
