I think the Romio package needs to have the nfslock service  (rpc.statd) 
running on each  nfs client and on the nfs server (eg the Front End and each 
compute node) when user directories are nfs mouinted.

As far as I can see RedHat 7.2 or later already does nfs version 3 by default.

nfslock is contained in the nfs-utils rpm package. nfs-utils needs to be added 
and nsflock service started.

nfs-utils was included in the Score 5.0 realease but not in the Score 5.4 
release.

Can  nfs-utils be added to later Score releases please ?

Thanks.
