Exceed the Limit of Volumes in a Storage Pool (Overbooking)

Deactivate/Activate Logical Volumes and Storage Pools

Fast Error Correction and Data Recovery

Immediately Save Data to Disk

Individual logical volumes cannot exceed the size of a storage pool. However,
you can create numerous volumes in a storage pool. Individual logical
volumes must be smaller than the storage pool, but the sum of multiple logical
volumes can exceed the pool size. This feature, called overbooking, can be an
efficient way to manage your file system.
For example, you might have a number of users who are individually assigned
to volumes with a limited amount of space for each volume. You can assign
volumes that collectively exceed the pool size if not all users fill up their
volumes. Essentially, the users can borrow space from other volumes in the
pool as long as there are volumes that are not filled to the limit. This way it is
not always necessary to add more disk space when some users reach or exceed
their volume limit.
You might need to temporarily prevent user access to storage pools or volumes
to do maintenance. Instead of bringing down the server, you can deactivate
individual storage pools to run the REBUILD and VERIFY utilities. When
you deactivate a storage pool, users will not have access to any of the volumes
in that pool. The REBUILD and VERIFY utilities generate log files to the root
of the DOS drive.
NSS quickly recovers data after a file system crash. Instead of scanning an
entire volume for corruption, NSS quickly replays the latest set of changes to
make sure they were written correctly. The file system either recovers the
changed information, or it returns the data to its original settings before the
transaction began. This is beneficial for applications such as mail services
because there is less server down time.
The Flush Files Immediately feature saves your file data to disk immediately
after you close the file instead of waiting for the next flush cycle. This ensures
that your data is not at risk of being lost between flush cycles.
