We found the issue. The ability to write to the Lustre FS was dependent on the synchronization of the user IDs between the MDS and the clients, which I assume LDAP/NIS would take care of (as you guys mentioned). Thank you for your help. I appreciate it.

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?

The mds_getxattr operation failed with -13." You likely miss authentication information on your MDS about the user you're trying to write as. Just configure NIS, LDAP or whatever you're using on your MDS, and you should be good to go.
