[Lustre-discuss] l_getgroups message

[Heiko Schroeter]

Hello,

from time to time we see these messages on our MDS 1.6.5.1 during copying data 
onto lustre.

Is this just informational or an indicator of a broken setup ? Network load 
problems ?

We checked the group rights and they look ok to us. The lustre MDS system 
including clients runs with YP setup.
It seems to us that the message comes 
from  "lustre-1.6.5.1/lustre/utils/l_getgroups.c". But we cannot nail down 
the real reason.

Thanks and Regards
Heiko
