To view the Deduplication file system page:
Navigate to Home > Storage Management > File Systems > Dedupe File Systems. The Deduplication page appears.


The following table describes the fields on this page:

Field/Item Description
File System Name Use to search by file system name.
EVS Use to search by a particular EVS.
Show
Use to search by type of file system version:
  • Converted file systems
  • Not converted file systems
  • All file systems
Filter Use to initiate your search criteria.
File Systems Displays a list of file systems that match the search criteria.
Used Capacity Displays the total amount of file system space in use, in GiB or TiB and as a percentage of the total.
Reclaimed Capacity Displays the space savings achieved by deduplication and/or file system packing, presented in bytes and in a percentage.

The percentage is the ratio of the saved space in bytes to the sum of the saved space in bytes and used capacity. Note that the dedupe process begins by taking a temporary snapshot of the file system and then dedupes it.

Status Displays the status:
  • Disabled: dedupe is disabled on the file system.
  • Enabled: dedupe is enabled on the file system.
  • Not converted: The file system needs to be converted in order to use the dedupe capability on the file system.
  • Not assigned to an EVS: File system is not assigned to an EVS and cannot be converted until the file system is assigned to an EVS.
  • EVS name (disabled): File system cannot be converted because the EVS is disabled. Enable the EVS first.
  • Converting: Starting to convert a file system to support deduplication.
  • Full run: Performing a full deduplication on the file system.
  • Incremental run: Performing an incremental deduplication on the file system.
EVS EVS to which the file system is assigned.
Last Run The date and time of the last dedupe run.
enable Dedupe-enables an existing file system.
disable Disables dedupe on an dedupe-enabled file system.
convert Starts the conversion process on a file system that needs conversion to support and enable dedupe. See the fs-convert-to-support-dedupe man page for important information and considerations before starting the conversion process. For example:
  • The file system should be in an unmounted state.
  • The file system must have sufficient space.
File System Returns to the File System page.
Active Tasks Displays the current status of the conversion process.
