Inconsistent documentation, gracefully removing backend nodes

[Navid Sassan]

Hello,

I am testing ProxySQL in front of a MariaDB Galera cluster and am
struggling to gracefully remove one of the Galera nodes. I set the
status to "OFFLINE_SOFT" according to the "Gracefully disabling a
backend server" section on
https://proxysql.com/documentation/backend-server-configuration/, but
the status always reverts to "ONLINE" after a few moments. I then found
the following comment
https://github.com/sysown/proxysql/issues/2098#issuecomment-1681637078
which seems to contradict the documentation. So my question is, what is
the correct way to gracefully remove a backend server?

Thanks and kind regards
Navid
