+1 to a real python API.
We have written our own, albeit incomplete, library to expose most of
what we need. We would be happy to share some general ideas on what
should be included, but a real IBM implementation wouldn’t have to do
what we did. (Think lots of subprocess.Popen + subprocess.communicate
and shredding the output of mm commands. And yes, we wrote a parser
which could shred the output of either –Y or tabular format.)
Thx

Someone should just make a python API that just abstracts all of this

So mmlspool does in 4.1.1.3... perhaps my memory fails me.
I'm pretty certain Yuri told me that mmlspool was completely
unsupported and didn't have -Y a couple of years ago when we did
the original GPFS UG RFEs prior to 4.x. I figure that earns cookies.
Perhaps in light of the mmbackup thread; "Will fix RFEs for
cookies?". Name your price ;-)

Indeed.
jtucker@elmo:~$ mmlsfs all -Y
mmlsfs::HEADER:version:reserved:reserved:deviceName:fieldName:data:remarks:
I must say I've not seen any headers increment above 0:1 since
... er .. 3.3(?), so they're pretty static.
Now, if only mmlspool supported -Y ... or if _all_ commands
supported -Y, I might even FedEX beer.

What’s nice is that the “-Y” output provides a HEADER so
that you can still programmatically determine fields of
interest… this is the best!
I recommend adding “-Y” option documentation to all
supporting GPFS commands for others to be informed.

If you build a monitoring pipeline using -Y output, make
sure you test between revisions before upgrading. The
columns do have a tendency to change from time to time.

Apparently, though not documented in man pages or any
of the GPFS docs that I’ve read (at least that I
recall), there is a “-Y” option to many/most GPFS
commands that provides output in machine readable
fashion….
That’s right kids… no more parsing obscure, often
changed output columns with your favorite
bash/awk/python/magic.
Why IBM would not document this is beyond me,
