Fork of seaweedfs/seaweedfs-csi-driver, renamed seaweedfs -> s3 throughout and ported off protobuf entirely. WHY a fork was unavoidable: hanzoai/s3 serves HanzoFiler over the native ZAP transport on the port still named "grpc" (18888) — s3/command/filer.go binds it with transport.ListenStream and says it "replaces the legacy gRPC HanzoFiler server: the whole filer (28 unary + 5 streaming RPCs) now answers over ZAP, no gRPC". RegisterHanzoFilerServer exists nowhere in that tree. So the upstream driver's gRPC client cannot connect at all; it fails as `Unimplemented: unknown service filer_pb.SeaweedFiler`, which LOOKS like a service-name mismatch but is a gRPC client hitting a non-gRPC port. Renaming the service in the client would not have helped. pkg/filer is the only place this driver touches storage, and it speaks ZAP: Mkdir -> CreateEntry (CreateVolume) Remove -> DeleteEntry (DeleteVolume) Exists -> LookupDirectoryEntry (ValidateVolumeCapabilities) One shared, concurrency-safe client multiplexes over a single ZAP connection, dials lazily so controller start does not depend on filer readiness, and redials exactly once on a transport fault (covers a filer restart closing an idle conn without becoming a retry storm against a struggling backend). pkg/driver/volume.go Quota() likewise moves to s3/wire/mount — the fork generates no mount_pb at all. Dead gRPC plumbing (WithFilerClient, AdjustedUrl, grpcDialOption) is deleted rather than left inert. The kubelet-facing side stays CSI gRPC: that is the Kubernetes contract between kubelet and any CSI driver, not a Hanzo choice. Zero protobuf call sites remain. Whole module compiles clean.
