Displaying File System Space Usage Information
Use the GUI, the VxDBA utility, or the Storage Checkpoint Capacity Planning utility to display space-usage information for VxFS file systems and the associated Storage Checkpoints. You can monitor this space-usage information as your Storage Checkpoint-creation schedules progress.
Usage Notes
- If a Storage Checkpoint is created using other tools and products (for example, through the VxDBA utility menus or VERITAS NetBackup), the following will occur when a Storage Checkpoint Capacity Planning schedule is in progress:
- The Storage Checkpoint Capacity Planning utility will fail the next time cron attempts to create a Storage Checkpoint at the time designated in the schedule you created.
- The Storage Checkpoint Capacity Planning utility will display the following error when displaying the Storage Checkpoint space information using the Display Space Usage Information operation:
DBED1007: Non-Capacity Planning Storage Checkpoints detected.
