Description Nag Pavan Chilakam 2019-10-18 10:12:29 UTC 
Description of problem:
===========================
currently we only support volumes of replica count 3
Any volume with replica count 2 throws a warning (which again needs a bit of modification as mentioned in BZ#1763124)

however glusterfs still create a volume of replica count >3 as below example, without any caution/warning.

[root@dhcp35-190 ~]# gluster v create rep rep 4 dhcp35-237.lab.eng.blr.redhat.com:/gluster/brick1/rep2 $HOSTNAME:/gluster/brick1/rep2 dhcp35-29.lab.eng.blr.redhat.com:/gluster/brick1/rep2 dhcp35-157.lab.eng.blr.redhat.com:/gluster/brick1/rep2 
volume create: rep: success: please start the volume to access data



We must throw a warning saying that " replica count other than or greater than  3 is not supported,"

This should be a fairly simple tests to automate. Do we have it automated?
