Expand metadata storage

Expand metadata storage by increasing the size of metadata disks.

Prerequisites

It is recommended that you expand metadata storage by adding new metadata disks. You can expand metadata storage by increasing the size of existing metadata disks when the:

  • Total number of metadata disks reaches its limit.
  • DDVE is upgraded from the 96 TB instance to the 256 TB instance.
  • Before expanding metadata storage, disable the file system.
  • You cannot expand the first metadata disk.
  • Observe the recommended increment size of 1 TiB.
  • Shrinking the metadata disk is not supported.

Steps

  1. Log in to the Azure portal, find your DDVE, and stop it.
  2. In the blade for the VM, select Disks from the menu.
  3. Select the metadata disk that you want to expand.
    NOTE The first metadata disk is not available for expansion.
  4. Select Size + Performance from the menu.
  5. Change the Size (GiB) of the disk (for example, from 1024 GiB to 2048 GiB).
  6. Select Resize and close the disk pane.
  7. To increase the size of other metadata disks, if required, repeat Step 3 to Step 6.
  8. Start the DDVE.
  9. Disable the file system with the filesys disable command.
  10. Expand metadata storage with the filesys expand command.
  11. Enable file system with the filesys enable command, and check file system status with filesys status command to ensure that it is running.
  12. To confirm the metadata storage expansion, use the filesys show space tier active local-metadata command.
