Hi All,
<div class=""><br class="">
</div>
<div class="">We recently upgraded our cluster (well, the servers are all upgraded; the clients are still in progress) from GPFS 4.2.1.1 to GPFS 4.2.2.1 and there appears to be a change in how mmrepquota handles group names in its’ output. 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.</div>
<div class=""><br class="">
</div>
<div class="">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.</div>
<div class=""><br class="">
</div>
<div class="">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).</div>
<div class=""><br class="">
</div>
<div class="">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… ;-)</div>
<div class=""><br class="">
</div>
<div class="">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. Thanks…</div>
