Installing couchbase via yum repo fails

Hello everyone,

A few weeks ago, I installed a 4 node clutser using this method:

curl -O
sudo rpm -i couchbase-release-1.0-0-x86_64.rpm
sudo yum -y install couchbase-server-community

And running those command, the following couchbase version was installed:

Today, I run the exact commands, but the following version is installed instead:

I decided to to download 4.1.0 instead on the download page and I notice only version 4.0.0 is available for download.

Anyone knows what happen?

How can I add a new node in my existing cluster using a consistent method like using a yum repo that dont break?
