<p>I have a 3 node cluster. What I am going to do is create a persistence volume with <strong>ReadWriteMany</strong> access mode for MySQL Deployment. Also, Mount Option is GCEPersistentDisk.
My question is if I could use ReadWriteMany access mode for MySQL deployment, Will it be an issue? Because the volume can be mounted by many nodes. if I am wrong please correct me.</p>

YMA
<p>Yes it can be an issue when the backend doesn't support ReadWriteMany, however, as per my knowledge MySQL supports ReadWriteMany. So it should not be an issue in your case.</p>
