FluidFS Version 5.0.100128 New Features and

Enhancements

Version 5.0.100128 introduced the following new features and enhancements.

Dedicated FluidFS Replay Profile

For FluidFS deployments, Dell Storage Manager creates a dedicated FluidFS replay that is automatically

assigned to FluidFS LUNs (volumes on the Storage Center). The profile setting defaults to Daily, and the

retention policy is to delete after 25 hours. This feature will take effect only during an initial installation of

FluidFS v5.0.100128. You cannot activate this feature if you are updating the firmware to v5.0.100128.

Automatic ACL to UNIX Word 777 Mapping

When files with Windows ACLs are displayed from NFS clients, the FluidFS mapping algorithm shows a

translated UNIX access mode. Perfect translation is not possible, so a heuristic method is used to

translate from the Windows ACL to the 12 bits of the UNIX word. However, when some special SIDs are

used inside ACL (for example, creator-owner ACE), the mapping can be inaccurate. For some

applications, NFS clients must see the exact mapping or a mapping for more permissive access.

Otherwise, the NFS applications might not perform denied operations.

This release adds an option that causes all objects with SMB ACLs to be presented with UNIX Word 777

from NFS clients (for display only). This option, which is disabled by default, can be configured under NAS

Volume settings.

NOTE: Actual data-access checks in FluidFS are still made against the original security ACLs.

This feature applies only to NAS volumes with Windows or mixed security style (for files with Windows

ACLs).
