Hi All,
<div class=""><br class="">
</div>
<div class="">Let me try to answer some questions that have been raised by various list members\u2026</div>
<div class=""><br class="">
</div>
<div class="">1. I am not using nscd.</div>
<div class="">2. getent group with either a GID or a group name resolves GID\u2019s / names that are being printed as GIDs by mmrepquota</div>
<div class="">3. The GID\u2019s in question are all in a normal range \u2026 i.e. some group names that are being printed by mmrepquota have GIDs \u201cclose\u201d to others that are being printed as GID\u2019s</div>
<div class="">4. strace\u2019ing mmrepquota doesn\u2019t show anything relating to nscd or anything that jumps out at me</div>
<div class=""><br class="">
</div>
<div class="">Here\u2019s another point \u2026 I am 95% sure that I have a client that was running 4.2.1.1 and mmrepquota displayed the group names \u2026 I then upgraded GPFS on it \u2026 no other changes \u2026 and now it\u2019s mostly GID\u2019s. I\u2019m not 100% sure because output scrolled
out of my terminal buffer.</div>
<div class=""><br class="">
</div>
<div class="">Thanks to all for the suggestions \u2026 please feel free to keep them coming. To any of the GPFS team on this mailing list, at least one other person has reported the same behavior \u2026 is this a known bug?</div>
<div class=""><br 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\u2019 output. I\u2019m trying to get a handle on
it, because it is messing with some of my scripts and - more importantly - because I don\u2019t understand the behavior.<br class="">
> <br class="">
> From one of my clients which is still running GPFS 4.2.1.1 I can run an \u201cmmrepquota -g <fs>\u201d and if the group exists in /etc/group the group name is displayed. Of course, if the group doesn\u2019t exist in /etc/group, the GID is displayed. Makes sense.<br class="">
> <br 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\u2019s 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\u2019 GID is instead (and yes, both exist in /etc/group).<br class="">
