问题:

I am trying to regain access to my databases stored in CouchDB, but the error This database failed to load. gets shown instead of the databases (see attachments).

  • I started seeing all of these errors at once
  • It be some user rights misconfiguration (1. The error This database failed to load. is normal, when lacking privileges, 2. The actions to delete or replicate a DB are missing). However, I am logged as admin.

Can you help me find the root cause of the error?

回答1:

The error was caused by update to CouchDB 2.1.1. It's explained on the CouchDB website that the new version brings breaking changes and a line has to be modified in the config file.

So I had to change this file:

$ sudo vim /opt/couchdb/etc/vm.args

-name couchdb@localhost changed to -name couchdb@127.0.0.1

Don't forget to move the DB shards to the new node and restart CouchDB.

This script is useful for migrating the DB shards to the new node:

#!/bin/bash
curl "http://admin:password@127.0.0.1:5986/_dbs/$1" > $1.json
cat $1.json | sed s/$2/$3/g > $1_edited.json
curl -X PUT "http://admin:password@127.0.0.1:5986/_dbs/$1" -d @$1_edited.json
