Fileset permissions

When you create and attach a new fileset to the global namespace, the fileset is owned by user Anonymous. A UNIX® root user or a Windows® administrator user must change the ownership and permissions of the fileset before the fileset is usable. (You must do this for the FlashCopy® directory and the lost+found directory under the fileset root.) You need to make these changes only once in the lifetime of a fileset. The changed permissions are persistent across metadata server restarts and whenever the fileset is detached or attached.

Unlike the requirement for the global fileset, a UNIX or Windows user can own a fileset exclusively. The fileset is not required to have write permissions for both UNIX and Windows domains.

Tip: If you change the permissions of a fileset after you create a FlashCopy image and then revert back to that FlashCopy image, the permissions also revert to the settings at the time when the FlashCopy image was taken.
