The XFS on disk format supports the required metadata for DMAPI, but the
implementation for it never made it into the mainline Linux kernel. For

purposes as free software, but I don't think that's what your looking
for. The main user of the XFS DMAPI support is SGI's DMF product,
and at least a few years ago IBM's Tivoli Storage Manager also supported
