4.1.0 HP PolyServe Matrix Server administration guide (T5392-96073, October 2010)

• Dynamic default quota. No explicit default limits are assigned to the user. Instead,
the effective limits applied to the user are the default values for the filesystem at
the time of each operation.
The File Accounting tab specifies whether real cost accounting or virtual cost
accounting should be used for sparse files.
• Real cost accounting. Sparse files are accounted against the file owner’s quota
according to the actual space used by the file (user data and metadata). This is
the default.
• Virtual cost accounting. Sparse files are accounted against the file owner’s quota
according to the entire virtual space used by the file (virtual user data and actual
metadata). This matches the NTFS policy.
If you want to change this option after the filesystem is created, you will need to
either disable quotas and then re-enable them with the changed option, or recreate
the filesystem.
Recreate a filesystem
To reformat a filesystem, select the filesystem on the Filesystems window, right-click,
and select Recreate. A message then appears stating that the Matrix Server needs
to unmount the filesystem and any unsaved files will be lost. When you click Yes, the
following window appears.
