Changing configuration characteristics to manage space
Options for managing space on the cluster include
• Changing snapshot retention—retaining fewer snapshots requires less space
• Changing schedules to snapshot a volume—taking snapshots less frequently requires less
space
• Deleting volumes or moving them to a different cluster
NOTE: Deleting files on a file system does not free up space on the SAN volume. For more
information, see “Block systems and file systems” (page 152). For file-level capacity management,
use application or file system-level tools.
