Good catch. I actually meant to ask for both uname and ulimit.

Add this line to your /etc/security/limits.conf:
root - nofile 32768

Log out and back in and do ulimit -a to make sure 'open files' now shows 
Either restart glusterfs/d in this shell, or edit your script that may 
start this and add the below before it starts gluster:
ulimit -n 32768

That should raise the per process fd limit for root.
