+1 for
a. automatic creation of metadata volume over manual
b. configuration through gluster cli

few suggestions
a. disable access through any mechanisms other than fuse/gfapi.(Samba and
NFS should not export.)
b. Restrict access to peer nodes.

Question:
What would be the replica count of the said volume and would that be ok for
every use case
mentioned above?

Thanks,
Raghavendra Talur
