Automatic Tarantool Recovery
=====================================

If your system architecture doesn't imply uninterrupted availability of Tarantool servers, it is recommended to enable automatic database recovery. In this case, each time an error occurs while reading a snapshot or xlog file, Tarantool will skip invalid records, read as much data as possible, and re-build the file. 

To enable automatic database recovery, do the following:

#. For each Tarantool shard, open the configuration file ``/etc/tarantool/instances.available/shard-*.lua`` and uncomment ``force_recovery = true``.

   .. code::

      sudo vi /etc/tarantool/instances.available/shard-*.lua


      box.cfg{

          force_recovery = true,
      }

#. Restart the shards.

   .. code::

      systemctl restart tarantool@shard-*
