CouchDB 2.1.1: Internal Server Error

Question

Before installing the CouchApp utility, the Sofa blog app and the sample DB myblogdb together with CouchDB 2.1.1 my CouchDB was working find and I never seeing any Internal Server Error.

In the last 2 hours a trojan attached itself as a process to the CouchDB. Since then I removed it, but it might have jammed some of the CouchDB's settings.

Why can't I run myblogdb? Does this error have something to do with the breaking changes caused by upgrade to CouchDB 2.1.1?

Firstly, couchapp push myblogdb only works on second attempt (first attempt ends in Internal Server Error):

$ couchapp push . http://admin:[email protected]:5984/myblogdb

Thirdly, I also receive Internal Server Error in Fauxton UI when creating/deleting any databases, but the request still gets executed:

Answer 1

It seems you are facing an issue in database creation/deletion due to a lack of cluster quorum: Issue 603 and Issue 1136.

Probably your migration from 2.0 to 2.1.1 has some effect in the membership of your node and now you have to nodes registered one for couchdb@localhost and another one for [email protected]

Couchdb is considering your instalation as a two-node cluster and you are facing the lack of quorum issues.

You can check it by using this URL http://<your-couchdb-host>:5984/_membership

It is possible to remove the wrong node in your config by follwing these instructions.
