Upgrading a file system to the current layout for running deduplication

FileStore deduplication will not work if the file system layout is not at the current version. The Storage> fs upgrade file_system_name command upgrades the file system layout to the current version.

Note:

The file system needs to be online for this command to proceed.

See About data deduplication.

You can find information about the file system version by using the Storage> fs list file_system_name command.
