Re: Multiple backends with NFSv4.1 (supports file locking): should work without Director, right?

Thanks Tom. Are you refering to a proxy software in particular (e.g. Dovecot proxy, Nginx, ...)? Do you mean having a single proxy in front of all the backends?

We'd prefer to avoid that if possible, as that makes the proxy a single point of failure. But it seems to be the recommended way to deal with cluster indeed (https://doc.dovecot.org/configuration_manual/nfs/#clustering-without-directo...).
