# MarkBase NFS Backend Implementation - Day 1 Complete
|
|
|
|
**Date:** 2026-05-17 13:40
|
|
**Status:** ✅ Phase 2 Started - MarkBaseFS backend created
|
|
**Progress:** 25% (MarkBaseFS struct created, tests passing)
|
|
|
|
---
|
|
|
|
## What We Completed
|
|
|
|
### 1. Created NFS Module Structure
|
|
- ✅ Added nfs module to `src/lib.rs`
|
|
- ✅ Created `src/nfs/mod.rs` (module export)
|
|
- ✅ Created `src/nfs/markbase_fs.rs` (236 lines)
|
|
|
|
### 2. Implemented vfs::FileSystem Trait
|
|
- ✅ `MarkBaseFS::new()` - SQLite connection creation
|
|
- ✅ `resolve_path()` - Path to node_id resolution (recursive query)
|
|
- ✅ `read_dir()` - Query children from file_nodes
|
|
- ✅ `open_file()` - Read file from disk (via aliases_json.path)
|
|
- ✅ `metadata()` - Query file_size, node_type
|
|
- ✅ `exists()` - Path existence check
|
|
- ✅ `create_dir()`, `create_file()`, etc. - NotSupported (read-only for now)
|
|
|
|
### 3. Error Handling
|
|
- ✅ Created `rusqlite_to_io_error()` helper
|
|
- ✅ Proper vfs::VfsErrorKind conversions
|
|
- ✅ Lock poisoning handling (Mutex)
|
|
|
|
### 4. Tests
|
|
- ✅ `test_markbase_fs_creation` - Tests SQLite connection
|
|
- ✅ `test_resolve_root` - Tests root path resolution
|

## Build Status
|
|
|
|
```bash
|
|
$ cargo build
|
|
Finished `dev` profile [unoptimized + debuginfo] target(s) in 3.36s
|
|
```
|
|
|
|
**Warnings:** 10 warnings (unused variables/imports)
|
|
**Errors:** 0 errors ✅

|
## What's Left (Phase 2-3)
|
|
|
|
### Day 2-3 Tasks
|
|
|
|
**Task 1: Integrate bold-nfs library**
|
|
- Add bold-nfs dependency to Cargo.toml
|
|
- Create NFS server binary (`src/bin/markbase-nfs.rs`)
|
|
- Connect MarkBaseFS to bold-nfs NFSServer
|
|
|
|
**Task 2: Test with warren.sqlite**
|
|
- Mount NFS volume
|
|
- Verify file tree visible (12659 nodes)
|
|
- Test file reading from mount point
|
|
|
|
**Task 3: Add caching**
|
|
- Implement LRU cache for node_id lookup
|
|
- Optimize SQLite queries (indexes)
|
|
- Add path caching (HashMap)
|
|
|

|
|
|
## Manual Test Still Needed
|
|
|
|
**From Phase 1:** You still need to manually test bold-nfs mount:
|
|
|
|
```bash
|
|
# Terminal 1: Start bold-mem server
|
|
cd /tmp/bold-nfs
|
|
./target/release/bold-mem exec/memoryfs.yaml
|
|
|
|
# Terminal 2: Mount NFS (use your password)
|
|
sudo mkdir -p /tmp/nfs_demo
|
|
sudo mount_nfs -o vers=4,port=11112 127.0.0.1:/ /tmp/nfs_demo
|
|
|
|
# Terminal 3: Test files
|
|
ls /tmp/nfs_demo/
|
|
cat /tmp/nfs_demo/home/user/file1
|
|
|
|
# Unmount
|
|
sudo umount /tmp/nfs_demo
|
|
```
|
|
|
|
**Report back:** Did mount succeed? Did files appear?
|
|
|
|
---
|
|
|
|
## Next Steps
|
|
|
|
**If mount succeeds:**
|
|
1. Continue Phase 2 implementation
|
|
2. Create `markbase-nfs` binary
|
|
3. Test with warren.sqlite
|
|
|
|
**If mount fails:**
|
|
1. Debug mount_nfs options
|
|
2. Try NFSv3 (`vers=3` option)
|
|
3. Consider libnfs-go fallback
|
