[gpfsug-discuss] mmrepquota and group names in GPFS 4.2.2.x

[Stephen Ulmer]

My list of questions that might or might not be thought provoking:

How about the relative position of the items in the /etc/group file?

Are all of the failures later in the file than all of the successes?

Do any groups have group passwords (parsing error due to “different" line format)?

Is the /etc/group sorted by either GID or group name (not normally required, but it would be interesting to see if it changed the problem)?

Is the set that is translated versus not translated consistent or do they change? (Across all axes of comparison by {node, command invocation, et al.})

Are the not translated groups more or less likely to be the default group of the owning UID?

Can you translate the GID other ways? Like with ls? (I think this was in the original problem description, but I don’t remember the answer.)

What is you just turn of nscd?
