[gpfsug-discuss] Get list of filesets _without_ running mmlsfileset?

[Simon Thompson]

Hi Kevin,

Have you looked at the rest API?

https://www.ibm.com/support/knowledgecenter/en/STXKQY_5.0.2/com.ibm.spectrum.scale.v5r02.doc/bl1adm_listofapicommands.htm

I don't know how much access control there is available in the API so not sure if you could lock some sort of service user down to just the get filesets command?

Subject: [gpfsug-discuss] Get list of filesets _without_ running mmlsfileset?

Hi All,

Happy New Year to all!  Personally, I’ll gladly and gratefully settle for 2019 not being a dumpster fire like 2018 was (those who attended my talk at the user group meeting at SC18 know what I’m referring to), but I certainly wish all of you the best!

Is there a way to get a list of the filesets in a filesystem without running mmlsfileset?  I was kind of expecting to find them in one of the config files somewhere under /var/mmfs but haven’t found them yet in the searching I’ve done.

The reason I’m asking is that we have a Python script that users can run that needs to get a list of all the filesets in a filesystem.  There are obviously multiple issues with that, so the workaround we’re using for now is to have a cron job which runs mmlsfileset once a day and dumps it out to a text file, which the script then reads.  That’s sub-optimal for any day on which a fileset gets created or deleted, so I’m looking for a better way … one which doesn’t require root privileges and preferably doesn’t involve running a GPFS command at all.

Thanks in advance.

Kevin

P.S.  I am still working on metadata and iSCSI testing and will report back on that when complete.
P.P.S.  We ended up adding our new NSDs comprised of (not really) 12 TB disks to the capacity pool and things are working fine.
