Expanding metadata (system) volumes

This topic describes how to increase the size of a system volume when the corresponding metadata LUN size has increased.

Prerequisites

You must have Administrator privileges to perform this task.

Context

Attention: You must reboot all of the metadata server engines to see the expanded volume size.

Steps

  1. Resize one or more metadata LUNs on your storage system (for example, IBM® Enterprise Storage System (ESS)).
  2. Reboot each subordinate metadata server engine in a rolling fashion.
  3. Reboot the master metadata server engine.
  4. Verify that all metadata servers can access the expanded volume with the new size using the lslun command from the administrative CLI.
  5. Run the expandvol command from the administrative CLI or perform the following steps using the SAN File System console:
    1. Click Manage Storage > Volumes from the My Work frame.
    2. Select a volume.
    3. Click Properties from the drop-down box in the table header.
    4. Click Go
    5. Click the Size tab.
    6. Determine the current LUN size by selecting a client that can see the LUN from the drop-down box and clicking Refresh.
    7. Check the LUN size versus the volume size in the table and click Expand Volume to increase the volume size if the LUN size has increased.
    8. Click OK to save the new settings.
