abuzooz Posted March 19, 2020 Report Share Posted March 19, 2020 Hi Community I want to configure Couchdb HA on my 3 node cluster so if one of the nodes fails the other 2 still supporting the system. CouchDB team told me that it is a built-in feature starting CouchDB V2, which is unfortunate as Kazoo is using CouchDB V1.1.1 and I cant find any article how to upgrade Kazoo-BigCouch to higher versions so I can support HA. Currently if I turned off one of the 3 nodes, the system collapse and start throwing errors. How have you overcame this issue using Kazoo V4.3?

safarov Posted March 23, 2020 Report Share Posted March 23, 2020 You deploy CouchDB cluster on dedicated host and configure HA-proxy to use this servers. Quote Link to comment Share on other sites More sharing options...

Firstly you should create a new cluster of CouchDB 2.3.1 then replicate all data from Bigcouch to new CouchDB cluster with using some utility from Kazoo repository. As far as I remember its clonedb. You can use even curl for this. Quote Link to comment Share on other sites More sharing options...
