I had a bit of a run-in with a gpfs developer at a conference once when I complained about how command output changes frequently, breaking customer scripts. He was confused why we weren’t using `-Y`, and didn’t believe me that it’s simply not documented anywhere!
`-Y` output is essential for interfacing programmatically with GPFS, and I don’t understand why it’s not mentioned in any of the guides or manpages. (Though apparently, according to this thead, it’s since appeared in some newer manpages.) ~jonathon On 3/28/17, 10:14 AM, "[email protected] on behalf of Marc A Kaplan" <[email protected] on behalf of [email protected]> wrote: Just looking/scanning the latest (4.2.2) Spectrum Scale Command (and Programming) Reference I only found a few commands that officially are documented as supporting a -Y option: mmnfs, mmsmb, mmuserauth. But as many of you have discovered, -Y is accepted and yields "interesting" output for many of the mmXXXX commands. Moreover the output *seems to* have easily discernible patterns that can be parsed by simple programs. I believe there is no guarantee that the exact command output formats will not change from release to release, so, as a practical matter, if you're going to parse command output, you're probably better off parsing the -Y output, even if that is not officially supported. _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
