Running percona xtradb without the cluster part

acerpaceracerpacer EntrantCurrent User Role Beginner

We are using percona xtradb cluster 5.6 on opensuse with 3 nodes.
Due to some another issue we won't be using cluster for next 2-3 months.

From my understanding percona xtradb can be run without cluster part if wsrep config is not included and mysql is started using start command instead of bootstrap.

I haven't tried it yet as it is running on live site but we are planning to shut down other 2 nodes as on the live machine mysql is eating lots of resources because it needs to sync across 3 nodes.

I think we can save some memory and cpu cycles by switching 2 nodes off and just starting mysql with start option.

Is that the right approach?
what precautions I should take while doing that?

Thanks in advance for your help.
