CP6-2 wires the CSI driver to SeaweedFS master/volume-server control plane: - Proto: block volume messages in master.proto/volume_server.proto, codegen - Master registry: in-memory BlockVolumeRegistry with Pending->Active status, full/delta heartbeat, inflight lock, placement (fewest volumes) - VS gRPC: AllocateBlockVolume/DeleteBlockVolume handlers, shared naming - Master RPCs: CreateBlockVolume (retry up to 3 servers), Delete, Lookup - Heartbeat: block volume fields wired into bidirectional stream - CSI Controller: VolumeBackend interface (Local + Master), returns volume_context - CSI Node: reads volume_context for remote targets, staged map + IQN derivation - Mode flag: --mode=controller/node/all, --master for control-plane - K8s manifests: csi-driver.yaml, csi-controller.yaml, csi-node.yaml csi-sanity conformance (33 pass, 58 skip) found 6 bugs: - BUG-SANITY-1/2/3: missing VolumeCapabilities/VolumeCapability validation - BUG-SANITY-4: NodePublish used mount instead of bind mount - BUG-SANITY-5: NodeUnpublish didn't remove target path - BUG-SANITY-6: NodeUnpublish failed on unmounted path k3s Level 4 (PVC->Pod data persistence) found 1 bug: - BUG-K3S-1: IsLoggedIn didn't handle iscsiadm exit code 21 226 CSI tests + 54 server tests = 280 new tests, all passing.
