From c84339ff93f87172ba50a100c8cc6cbc06f4ba72 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 24 Nov 2025 19:09:42 +0000 Subject: [PATCH] Refactor main driver share management to WebSocket API MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BREAKING CHANGES: - Completely rewrote createShare and deleteShare methods (1,621 lines → 691 lines) - Removed all SSH-based volume expansion code - Removed all API v1/v2 version conditionals from share management - Added full NVMe-oF support (subsystem and namespace management) - Removed SMB support (use NFS or iSCSI instead) Changes: - Replaced massive legacy createShare (1,203 lines) with clean modular implementation - Split into createNFSShare, createISCSIShare, createNVMeOFShare methods - Replaced massive legacy deleteShare (417 lines) with clean modular implementation - Split into deleteNFSShare, deleteISCSIShare, deleteNVMeOFShare methods - Added NVMe-oF ZFS property constants for tracking subsystem and namespace IDs - Simplified getMaxZvolNameLength() - always returns 255 for SCALE - Simplified expandVolume() - middleware handles reloads automatically - Removed getIsScale() checks - we're SCALE-only now - All share operations now use clean WebSocket JSON-RPC methods File size: 4,469 lines → 3,431 lines (-23%) The driver now provides clean, maintainable code with full support for: - NFS shares (path-based) - iSCSI targets (target/extent/association) - NVMe-oF subsystems (subsystem/namespace) --- src/driver/freenas/api.js | 2188 ++++++++++--------------------------- 1 file changed, 569 insertions(+), 1619 deletions(-) diff --git a/src/driver/freenas/api.js b/src/driver/freenas/api.js index c5df0a0..fdd1234 100644 --- a/src/driver/freenas/api.js +++ b/src/driver/freenas/api.js @@ -10,17 +10,18 @@ const Handlebars = require("handlebars");
