Numbers of bricks is not a multiple of replica count - glusterfs

I have 10 servers and want to use all as storage so tried to create volume with following command but its throwing error

gluster volume create gv0 replica 3 server1:/data/brick1/gv0 server2:/data/brick1/gv0 server3:/data/brick1/gv0 server4:/data/brick1/gv0 server5:/data/brick1/gv0 server6:/data/brick1/gv0 server7:/data/brick1/gv0 server8:/data/brick1/gv0 server9:/data/brick1/gv0 server10:/data/brick1/gv0 

and it throws error

Numbers of bricks is not a multiple of replica count

what's recommendation in this scenario?

it look like if i create with replica 2 it will succeed, so what would be difference in my scenario if i create volume with replica 2 or replica 3(i am assuming i will use 9 bricks here) on 10 brick?

In replica 2 with 10 brick scenario will i face split brain issue?

To store 3 copies of everything, you need 3N disks. 10 is not a multiple of 3.

3 copies seems like overkill, especially if they are all in the same building -- that is subject to the same fire, flood, earthquake, hurricane, or whatever. Or can you spread them out geographically?
