Cluster Troubleshooting

If your Seq Disaster Recovery (DR) Instance is is failing to sync, check out the frequently-encountered errors below. Feel free to contact the Seq support team for another set of eyes on it!

The node failed at the follower with: the replication can't be completed because the leader is part of a different group

This generally indicates that the follower instance was started/initialized before joining the cluster; the error is caused by a safety mechanism intended to prevent deletion of existing data by mistake.

You can resolve this by stopping the follower node, and deleting its Stream/ subfolder under the Seq storage root (the default location will be C:\ProgramData\Seq on Windows, or the /data volume mount under Docker) before starting it back up.
