9.2 What are the features that can be enabled for a new volume?

The below features can be enabled while creating a new volume.

  • Salvage

    The Salvage Files attribute enables deleted files to remain on the volume until the Purge Delay time expires or until space is needed on the volume for other data. Until the Purge Delay time expires, the Salvage feature tracks the deleted files and allows the deleted files to be salvaged and restored. If space is needed, the oldest deleted files are purged to clear space. Salvage is enabled by default. If the Salvage Files attribute is disabled, deleted files are purged immediately on deletion.

  • User Quotas

    The User Quotas (user space restrictions) attribute enables you to assign a maximum quota of space that a user’s data can consume across all directories in the volume.

  • Directory Quotas

    The Directory Quotas attribute enables you to assign a maximum quota of space that a directory can consume.

  • This option lets you enable access to the AD users for the selected volume. For a volume (both NSS32 and NSS64) to be accessible to the AD users, it should be part of a pool that is AD media upgraded, and it should be AD-enabled.

  • Compression

    The Compression attribute activates file compression in NSS volumes. Compression can be activated at creation time only and this choice persists for the life of the volume. Data in the volume is stored normally or in compressed form, depending on how frequently it is used. Compression parameters can be set at the server level to control compression behaviour.

  • Encryption

    Encryption provides password-protected activation of encrypted NSS volumes. Encryption can be activated at creation time only, and this choice persists for the life of the volume.

  • Event File List (EFL)

    NSS uses the Event File List (EFL) feature to track files that have changed on a volume during an interval called an epoch. It logs changes that are made to data and metadata for each active epoch on a specific NSS volume. You can use the API commands in scripts to start and stop an epoch, reset the event list for an epoch, and to affect how long epochs are retained.

    NOTE:The feature, Event File List (EFL) is selected by default and you cannot deselect it.
