Hi All,
<div class=""><br class="">
</div>
<div class="">Let me answer Skylar’s questions in another e-mail, which may also tell whether the rest API is a possibility or not.</div>
<div class=""><br class="">
</div>
<div class="">The Python script in question is to display quota information for a user. The mmlsquota command has a couple of issues: 1) its output is confusing to some of our users, 2) more significantly, it displays a ton of information that doesn’t apply
to the user running it. For example, it will display all the filesets in a filesystem whether or not the user has access to them. So the Python script figures out what group(s) the user is a member of and only displays information pertinent to them (i.e.
the group of the fileset junction path is a group this user is a member of) … and in a simplified (and potentially colorized) output format.</div>
<div class=""><br class="">
</div>
<div class="">And typing that preceding paragraph caused the lightbulb to go off … I know the answer to my own question … have the script run mmlsquota and get the full list of filesets from that, then parse that to determine which ones I actually need to display
quota information for. Thanks!</div>

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?<br class="">

Subject: [gpfsug-discuss] Get list of filesets _without_ running mmlsfileset?<br class="">
<br class="">
Hi All,<br class="">
<br class="">
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!<br class="">
<br class="">
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.<br class="">
<br class="">
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.<br class="">
<br class="">
Thanks in advance.<br class="">
<br class="">
Kevin<br class="">
<br class="">
P.S. I am still working on metadata and iSCSI testing and will report back on that when complete.<br class="">
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.<br class="">
