[gpfsug-discuss] Cloning across fileset boundaries

[Yuri L Volobuev]

This is technically impossible.  A clone relationship is semantically
similar to a hard link.  The basic fileset concept precludes hard links
between filesets.  A fileset is by definition a self-contained subtree in
the namespace.

Hi All,

When I use "mmclone copy" to try and create a clone and the destination is
inside a fileset (dependent or independent), I get this:

mmclone: Invalid cross-device link

I can find no information in any manuals as to why this doesn't work
(though I can imagine what the reasons might be). Could somebody explain
whether this could be permitted in the future, or if it's technically
impossible?

Thanks,
Luke.
