bsp;However, I was just able to perform Lustre operations as another user. So now it seems that only one of my users exhibits the problem I saw. I don't have NIS or LDAP configured on this MDS, but I have another Lustre FS setup elsewhere that does not exhibit any of the problems I've seen. Any thoughts as to why now only one user cannot access the Lustre FS?<br><br>Thanks,<br>Carl<br><br>-----Original Message-----<br>From: Kilian CAVALOTTI [mailto:<a href="mailto:kilian.cavalotti.work@gmail.com">kilian.cavalotti.work@gmail.com</a>]<br>Sent: Wednesday, October 12, 2011 2:24 AM<br>To: Barberi, Carl E<br>Cc: <a href="mailto:lustre-discuss@lists.lustre.org">lustre-discuss@lists.lustre.org</a><br>Subject: EXTERNAL: Re: [Lustre-discuss] Unable to write to the Lustre File System as any user except root<br><br>Hi Carl,<br><br>On Tue, Oct 11, 2011 at 9:07 PM, Barberi, Carl E<br><<a href="mailto:carl.e.barberi@lmco.com">carl.e.barberi@lmco.com</a>> wrote:<br>> “ LustreError: 11-0: an
