The reachability check called showmount, which speaks the MOUNT protocol. The ganesha export sets NFS_CORE_PARAM Protocols = 4 and Enable_NLM = false, and every EXPORT block repeats Protocols = 4, so MOUNT is never registered and showmount cannot succeed against a healthy server. The repo already records this elsewhere: scripts/tests/deploy/swarm/utils/collect/diagnostics.sh:125 prints "showmount -e failed; NFSv4-only servers do not answer MOUNT". Every failure fed status, and a nonzero exit reaches OnFailure, which starts sys-ctl-cln-anon-volumes (dockreap --no-confirmation). So on any host holding both anonymous and NFS volumes the check has been failing on every run and reaping volumes for a reason that was never true. Probing tcp/2049 is what the role does for its own readiness gate in files/nfs-ganesha-restart.conf:9, and it is correct for the kernel flavor too. The two tests drive a whitelisted anonymous volume so the anonymous section contributes nothing and the exit status reflects only the NFS check. One asserts a listening port passes, the other that a refused one fails; the first is the regression guard, the second keeps the check from being one that always fails.
