In a DR configuration, manual recovery is required in the event of leader node failure.
If, after reading these instructions you're unsure about how to recover your Seq instance, please reach out to
[email protected]for help 🙂
If the leader node catastrophically fails or is otherwise lost, the follower node can be promoted to become the new leader.
Windows: At an administrative shell prompt, promote the old follower to become the new leader by running:
seq node lead seq service restart
Docker: In an init script run:
#!/bin/bash seqsvr node lead
After the init script is run, the server process will start automatically.
Once a follower has been promoted this way, the old (failed) leader, if recoverable, should not be restarted until the
seq node followcommand has been run on it to set it back into the follower state
