There's a configuration example in the Jepsen test:

ra-kv-store/jepsen/jepsen.rakvstore/src/main/java/com/rabbitmq/jepsen/Utils.java

Lines 74 to 92 in 75addee

	String configuration =
	String.format(
	"[\n"
	+ erlangNetTickTime
	+ " {ra, [\n"
	+ " {data_dir, \"/tmp/ra_kv_store\"},\n"
	+ " {wal_max_size_bytes, %d}\n"
	+ " ]},\n"
	+ " {ra_kv_store, [\n"
	+ " {port, 8080},\n"
	+ " {nodes, [%s]},\n"
	+ " {server_reference, ra_kv%s},\n"
	+ " {release_cursor_every, %d}\n"
	+ " ]}\n"
	+ "].",
	walMaxSizeBytes,
	String.join(", ", nodes),
	nodeIndex,
	releaseCursorEvery);

.

If you decompress the archive file in e.g. /opt/rakvstore, the configuration must be /opt/rakvstore/releases/1/sys.config.
