# 4-node 4-disk distributed e2e lane.
#
# Each selected test starts a real localhost cluster via
# `RustFSTestClusterEnvironment` (4 processes; 4 drives per node unless the
# case is a two-site 4-node 1-drive pair or a 4-node upgrade). Membership is
# `[profile.e2e-distributed]` in `.config/nextest.toml`. This is not a required
# merge check: it is the scheduled/dispatch counterpart to the hardware
# functional chain that currently clones rustfs/auto-testing onto three VMs.
# Upgrade cases download the same pinned previous release as e2e-upgrade.yml.
