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