Gluster users - Feb 2016 - Replicated Volume (mirror) on 17 nodes.

Hi all :)

I would need soon to create a pool of 17 nodes. Each node requires a copy
of the same file "locally" so that can be accessed from the deployed
application.

* Do you see any performance issue in creating a Replica Set on 17 nodes ?
Any best practice that I should follow ?

* An other question: in case there's no problem then on this line

gluster volume create gv0 replica* 2* server1:/data/brick1/gv0
server2:/data/brick1/gv0

do i need to provide 17 instead of 2 ?

Sorry for my basic questions.

Thanks a lot for your support!

Simone

I don't know what your use case is but I don't think you want to create 
so many replicas. Why not just create a glusterfs volume  of replica-2 
or replica-3 or even an arbiter volume, and mount them on all 17 nodes?
I think replica 4 is what some people in the community have used at the 
max but even that is an overkill IMO.
