How to do it...
For this recipe, we should already have three PostgreSQL servers. As before, we'll assume they are named pgha1, pgha2, and pgha3. Follow these steps to fix the broken system:
- Remove the contents of the corrupt cluster by running the following command as the postgres user on the broken system:
rm -Rf /db/pgdata
- Start a new patroni daemon with this command as a root-enabled user:
sudo systemctl start patroni
- Follow the Patroni log with this command:
sudo journalctl -u patroni -f
