I'm trying to set up nodemaps on a new lustre file system. Presently when I turn on the nodemaps I get permission denied for servers in the default nodemap.</div>

I've defined two custom nodemaps. An AdminSystems nodemap (for servers that will need to perform actions as root, and a LustreServers nodemap (for the lustre servers themselves)<br>

Every other client will be in the default map. (whose gid/uid/projid mappings we trust)</div>

Our desired end state is an Admin nodemap we can add and remove systems to as needed that can take action as root, and all other lustre clients being able to access the file system, but having no root access. The LustreServers nodemap is there to keep the
lustre file servers themselves safe from any unexpected changes.</div>
