- To start replication of the datastores, use the
ghe-repl-start
command.
$ ghe-repl-start
{% warning %}
**Warning:** `ghe-repl-start` causes a brief outage on the primary server, during which users may see internal server errors. To provide a friendlier message, run `ghe-maintenance -s` on the primary node before running `ghe-repl-start` on the replica node to put the appliance in maintenance mode. Once replication starts, disable maintenance mode with `ghe-maintenance -u`.
