Deleting a fileset

There are several notes to keep in mind when deleting filesets:

• The root fileset cannot be deleted.
• A fileset that is not empty cannot be deleted unless the -f flag is specified.
• A fileset that is currently linked into the namespace cannot be deleted until it is unlinked with the mmunlinkfileset command.
• A dependent fileset can be deleted at any time.
• An independent fileset cannot be deleted if it has any dependent filesets or fileset snapshots.
• Deleting a dependent fileset that is included in a fileset or global snapshot removes it from the active file system, but it remains part of the file system in a deleted state.
• Deleting an independent fileset that is included in any global snapshots removes it from the active file system, but it remains part of the file system in a deleted state.
• A fileset in the deleted state is displayed in the mmlsfileset output with the fileset name in parenthesis. If the -L flag is specified, the latest including snapshot is also displayed. The --deleted option of the mmlsfileset command can be used to display only deleted filesets.
• The contents of a deleted fileset are still available in the snapshot, through some path name containing a .snapshots component, because it was saved when the snapshot was created.
• When the last snapshot that includes the fileset has been deleted, the fileset is fully removed from the file system.
