It is not required . By default , FSAL GLUSTER will use pnfs for nfsv4.1.

Only the thing you used be carefully that , current architecture 
supports single mds and multiple ds.

Also you should required to run  nfs-ganesha daemon(will act as DS) on 
every node which contains brick in the trusted pool.

MDS can be any node inside trusted pool or outside the trusted pool.

For nfs-ganesha , latest source code (v2.2-rc6) need to be used.

Thanks,
Jiffin
