Hi, I’ve setup a 3 Node XtraDB Cluster with ProxySQL. **What I would like to setup with this now:** Only one of the 3 servers should be the write node, the other 2 should only be read nodes. I’ve read about the read-write-split to configure but this seems to be like static linking one special node as write node… Is there a way to configure one server as write and the other two as read nodes, but if the write server will go down another previous read-only-server will take over the write role? Happy for any hints 🙂 ---

Hello @A.Wormuth, Check out the ProxySQL documentation on configuring Galera/PXC > **[Galera Configuration - ProxySQL](https://proxysql.com/documentation/galera-configuration/)** > > ProxySQL support for Galera ProxySQL provides the following parameters and configuration tables specifically for Galera: Health \[…\] ProxySQL will auto-manage which node goes into the writer HG so that you only have 1 writer at a time. If that node goes offline, proxysql will move one of the readers.
