## Binary Verification
|
||||
|

|
||||
|
||||

|
||||
|
||||
## MarkBase Integration
|
||||
|
||||
### Updated Backend Detection
|
||||
```rust
|
||||
// src/fuse/backend.rs
|
||||
pub fn detect_fuse_t_binary() -> bool {
|
||||
Path::new("/Library/Application Support/fuse-t/bin/go-nfsv4").exists()
|
||||
}
|
||||
|
||||
pub fn get_fuse_t_path() -> Option<PathBuf> {
|
||||
if detect_fuse_t_binary() {
|
||||
Some(PathBuf::from("/Library/Application Support/fuse-t/bin/go-nfsv4"))
|
||||
} else {
|
||||
None
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Status Check
|
||||
```bash
|
||||
$ cargo run -- fuse status
|
||||
|
||||
=== FUSE Status ===
|
||||
FUSE-T binary: ✓ Installed
|
||||
Path: /Library/Application Support/fuse-t/bin/go-nfsv4
|
||||
NFS-T binary: ✓ Available (go-nfsv4)
|
||||
Active FUSE mounts: 0
|
||||
|
||||
macOS version: 26.4.1
|
||||
Recommended backend: fskit
|
||||
```
|
||||
|
||||
### Unit Test Result
|
||||
```bash
|
||||
$ cargo test fuse::backend::tests::test_fuse_t_binary_detection
|
||||
|
||||
running 1 test
|
||||
test fuse::backend::tests::test_fuse_t_binary_detection ... ok
|
||||
test result: ok. 1 passed; 0 failed; 0 ignored
|
||||
```
|
||||
|
||||

|
||||
|
||||
## FUSE-T vs Expected Path
|
||||
|
||||
### Expected Path (Documentation)
|
||||
- `/usr/local/bin/fuse-t` ❌ Not found
|
||||
- `/usr/local/bin/nfs-t` ❌ Not found
|
||||
|
||||
### Actual Path (Installed)
|
||||
- `/Library/Application Support/fuse-t/bin/go-nfsv4` ✅ Found
|
||||
|
||||
### Binary Name
|
||||
- **go-nfsv4** (not `fuse-t` or `nfs-t`)
|
||||
- Version: 1.2.6
|
||||
- Size: 20MB
|
||||
|
||||
### Reason for Difference
|
||||
FUSE-T uses a unified binary (`go-nfsv4`) that supports multiple backends:
|
||||
- NFSv4 backend (--backend nfs)
|
||||
- FSKit backend (--backend fskit)
|
||||
- SMB3 backend (--backend smb)
|
||||
|

|
||||
|
||||
## Next Steps
|
||||
|
||||
### Phase 2: Real FUSE Mount
|
||||
|
||||
**Ready to Implement:**
|
||||
1. Use `/Library/Application Support/fuse-t/bin/go-nfsv4` binary
|
||||
2. Select backend (--backend nfs or --backend fskit)
|
||||
3. Implement real mount() function
|
||||
4. Test with warren user (12,659 nodes)
|
||||
|
||||
**Mount Command Example:**
|
||||
```bash
|
||||
# NFSv4 backend
|
||||
"/Library/Application Support/fuse-t/bin/go-nfsv4" \
|
||||
--backend nfs \
|
||||
--location /tmp/test_fuse \
|
||||
/Volumes/MarkBase_test
|
||||
|
||||
# FSKit backend (macOS 26+)
|
||||
"/Library/Application Support/fuse-t/bin/go-nfsv4" \
|
||||
--backend fskit \
|
||||
--location /tmp/test_fuse \
|
||||
/Volumes/MarkBase_test
|
||||
```
|
||||
|
||||
### Testing Plan
|
||||
|
||||
1. **Simple Mount Test**
|
||||
```bash
|
||||
# Create test directory
|
||||
mkdir -p /tmp/test_source
|
||||
echo "Hello FUSE" > /tmp/test_source/test.txt
|
||||
|
||||
# Mount using FUSE-T
|
||||
cargo run -- fuse mount --user test --dir /Volumes/MarkBase_test --backend nfs
|
||||
|
||||
# Verify
|
||||
ls /Volumes/MarkBase_test
|
||||
cat /Volumes/MarkBase_test/test.txt
|
||||
```
|
||||
|
||||
2. **Warren User Mount**
|
||||
```bash
|
||||
cargo run -- fuse mount --user warren --dir /Volumes/MarkBase_warren --backend fskit
|
||||
|
||||
# Expected: 12,659 nodes visible
|
||||
ls /Volumes/MarkBase_warren | wc -l
|
||||
```
|
||||
|
||||
3. **Unmount Test**
|
||||
```bash
|
||||
cargo run -- fuse unmount --dir /Volumes/MarkBase_test
|
||||
mount | grep MarkBase # Should be empty
|
||||
```
|
||||

## Documentation Updates
|
||||
|
||||
**Updated Files:**
|
||||
- `src/fuse/backend.rs` - Added detect_fuse_t_binary() and get_fuse_t_path()
|
||||
- `src/main.rs` - Updated status command to use correct path
|
||||
- `docs/FUSE_INSTALLATION.md` - To be updated with actual path
|
||||
|
||||
**Key Learnings:**
|
||||
1. FUSE-T binary is NOT at `/usr/local/bin/fuse-t`
|
||||
2. Actual location: `/Library/Application Support/fuse-t/bin/go-nfsv4`
|
||||
3. Binary name: `go-nfsv4` (unified multi-backend binary)
|
||||
4. Supports --backend parameter (nfs, fskit, smb)
|
||||
