Hi,

I've reinstalled Centos minimal on 3 hosts.
Configured replica 3 gluster storage for engine & data.
Configured dns entry in /etc/hosts for all three host and ovirt engine also.
*yum install ovirt-engine-appliance*
*hosted-engine --deploy*

Choose glusterfs storage for engine. Installation failed at last step "This
system is not reliable".

My host have low memory & processor so don't know it might be the issue.


Please help.
