For the benefit of those on digest, here's Carl's list again in plain text (I hope). I have also notified our documentation team that this is of great interest to clients, so they are aware.
In the 4.2.3 draft documentation, the -y option information has been added to a number of commands: -Y option Added the -Y option to the following commands: mmblock mmhealth mmlsfileset mmlsnodeclass mmnetverify mmcloudgateway mmkeyserv mmlsfs mmlsnsd mmnfs mmdf mmlscluster mmlslicense mmlspolicy mmrepquota mmdiag mmlsconfig mmlsmgr mmlsquota mmsmb mmgetstate mmlsdisk mmlsmount mmlssnapshot mmuserauth Alecia A.

Date: Tue, Mar 28, 2017 7:17 PM 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 Ellei edell? ole toisin mainittu: / Unless stated otherwise above: Oy IBM Finland Ab PL 265, 00101 Helsinki, Finland Business ID, Y-tunnus: 0195876-3 Registered in Finland ------------------------------ Message: 3 Date: Tue, 28 Mar 2017 16:37:12 +0000 From: "Simon Thompson (Research Computing - IT Services)" <[email protected]> To: gpfsug main discussion list <[email protected]> Subject: Re: [gpfsug-discuss] -Y option for many commands, precious few officially!
