Hi Olaf, We will continue upgrading clients in a rolling fashion, but with ~700 of them, it’ll be a few weeks. And to me that’s good … I don’t consider figuring out why this is happening a waste of time and therefore having systems on both versions is a good thing.
While I would prefer not to paste actual group names and GIDs into this public forum, I can assure you that on every 4.2.1.1 system that I have tried this on: 1. mmrepquota reports mostly GIDs, only a few group names 2. /etc/nsswitch.conf says to look at files first 3. the GID is in /etc/group 4. length of group name doesn’t matter I have a support contract with IBM, so I can open a PMR if necessary. I just thought someone on the list might have an idea as to what is happening or be able to point out the obvious explanation that I’m missing. ;-) Thanks… Kevin On Jan 19, 2017, at 10:05 AM, Olaf Weiser <[email protected]<mailto:[email protected]>> wrote: unfortunately , I don't own a cluster right now, which has 4.2.2 to double check...

Also, I didn’t mention this yesterday but our /etc/nsswitch.conf has “files” listed first for /etc/group. In addition to a mixture of GPFS versions, we also have a mixture of OS versions (RHEL 6/7). AFAIK tell with all of my testing / experimenting the only factor that seems to change the behavior of mmrepquota in regards to GIDs versus group names is the GPFS version. Other ideas, anyone? Is anyone else in a similar situation and can test whether they see similar behavior? Thanks...

I’m trying to get a handle on it, because it is messing with some of my scripts and - more importantly - because I don’t understand the behavior. From one of my clients which is still running GPFS 4.2.1.1 I can run an “mmrepquota -g <fs>” and if the group exists in /etc/group the group name is displayed. Of course, if the group doesn’t exist in /etc/group, the GID is displayed. Makes sense. However, on my servers which have been upgraded to GPFS 4.2.2.1 most - but not all - of the time I see GID numbers instead of group names. My question is, what is the criteria GPFS 4.2.2.x is using to decide when to display a GID instead of a group name? It’s apparently *not* the length of the name of the group, because I have output in front of me where a 13 character long group name is displayed but a 7 character long group name is *not* displayed - its’ GID is instead (and yes, both exist in /etc/group). I know that sample output would be useful to illustrate this, but I do not want to post group names or GIDs to a public mailing list … if you want to know what those are, you’ll have to ask Vladimir Putin… ;-) I am in the process of updating scripts to use “mmrepquota -gn <fs>” and then looking up the group name myself, but I want to try to understand this.
