Reseeding a replica

If any of a replica’s write-ahead log or snapshot files are corrupted or deleted, you can reseed the replica. This procedure works only if the master’s write-ahead logs are present.

1. Stop the replica using the tt stop command.

2. Delete write-ahead logs and snapshots stored in the var/lib/<instance_name> directory.

   Note

   var/lib is the default directory used by tt to store write-ahead logs and snapshots. Learn more from Configuration.

3. Start the replica using the tt start command. The replica should catch up with the master by retrieving all the master’s tuples.

4. (Optional) If you’re reseeding a replica after a replication conflict, you also need to restart replication.
