# Stop simulated multi-node cluster.
# Stops services in reverse order (node3 → node2 → node1).
# Usage: ./scripts/stop-multi-node.sh
# TODO: Reverse order, predastore running on node1
# BUG: Need to wait for each QEMU to flush/commit WAL to disk > S3, before shutdown, else corruption may occur
# BUG: nbdkit: ramdisk.3: debug: sending error reply: Cannot send after transport endpoint shutdown
# TODO: Fallback, if WAL on local disk not flushed, on boot, viperblock should commit and verify. Requires UT and test-cases
