Troubleshoot MongoDB¶

This section instructs you on how to troubleshoot the MongoDB failures.

To troubleshoot MongoDB:

1. Log in to the MongoDB shell as Administrator into the admin collection:

   mongo -uadmin -p$(salt-call pillar.get mongodb:server:admin:password|tail -1|tr -d ' ') admin
   

2. Verify the replica set configuration and status:

   rs.conf()
   rs.status()
   

3. To force synchronization of one of the replicas, delete data in the replica directory and start MongoDB:

   Caution

   Proceed with caution to avoid any data loss.

   service mongodb stop
   mv /var/lib/mongodb /var/lib/mongodb.backup
   mkdir /var/lib/mongodb
   chown mongodb:mongodb /var/lib/mongodb
   service mongodb start
