Xsan 2.2 or later: Use same native extended attributes setting when multiple Xsan volumes are in use

When ACLs are in use, copying files from an Xsan volume with native extended attributes enabled, to an Xsan volume without native extended attributes enabled, can result in the creation of AppleDouble files that do not have the intended ACLs. This can result in unexpected behavior when attempting to manipulate files with extended attributes.

In environments where multiple Xsan volumes with ACLs enabled are used, and files might be copied between them, support for native extended attributes should be consistent across each volume. If native extended attributes are enabled for one Xsan volume, they should be enabled for all Xsan volumes in use on the SAN.

Native extended attributes are a feature of Xsan 2.2 and later. This article does not apply to deployments that use earlier versions of Xsan software.
