Dear SpectrumScale team,
even after 5 years, this idea is still listed as "Not under consideration".
The former guest comment about "significant performance improvements for mmdsh" is of no help either, since running "
mmdsh -N all lsof +D /path/to/FilesetJunctionPoint/" is still unfeasible for large and remote clusters.As the filesystem manager ('
sgmgr') needs to know anyhow which files/directories are open on arbitrary (remote cluster) nodes: why can't we ask this central component directly, on which nodes a certain fileset/directory has open handles...?Is SpectrumScale a distributed file system or not - and in the case it is, it should be able to directly answer such "questions about distributed use" without clumsy workarounds like "
mmdsh".It would be no problem if the output only were the internal node identfier like
<c2n630>, as this could be resolved with "mmdiag --network".Please re-consider this suggestion - it would be a great help in case of
Thanks!

There is a significant planned performance improvement in mmdsh -n all targeted for 5.0.3. We ask that you evaluate that feature (either in Beta or GA) and let us know if it addresses the requirement sufficiently.
