I can’t figure out how to configure nextcloud to use a external redis cluster with master and slaves as a cache.
I have read that this is supported, but despite of very long and deep searches on the web, i couldn’t find any explanation on how to configure it.
I have a two nodes redis cluster working, with a master and a slave. If I configure the master node in the nextcloud config.php file, it works like a charm. But if the master redis node fails, nothing seems to handle the redirection on the old slave and promote it as new master.
Maybe I should use somewhere redis-sentinel to promote the slave to master, but how announce it to nextcloud ?
If someone has informations about that, or links where I can find it, thanks a lot !
