## 🔧 FUSE-T Binary Details
|
||||
|
||||
### Binary Information
|
||||
```
|
||||
Path: /Library/Application Support/fuse-t/bin/go-nfsv4-1.2.6
|
||||
Symlink: go-nfsv4 -> go-nfsv4-1.2.6
|
||||
Size: 20MB
|
||||
Version: 1.2.6
|
||||
```
|
||||
|
||||
### Supported Backends
|
||||
- **nfs** (default) - NFSv4 backend
|
||||
- **fskit** - FSKit backend (macOS 26+, fastest)
|
||||
- **smb** - SMB3 backend
|
||||
|
||||
### Binary Options
|
||||
```bash
|
||||
--backend string backend type (default "nfs")
|
||||
--location string location (default "fuse-t")
|
||||
--attrcache cache attributes (default true)
|
||||
--noatime don't set access time
|
||||
--debug debug mode
|
||||
--console output logs to console
|
||||
```
|
||||
|
||||
### Library Files
|
||||
```
|
||||
libfuse3.4.dylib
|
||||
libfuse-t-1.2.6.dylib
|
||||
libfuse3.dylib
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 📊 技術突破總結
|
||||
|
||||
### 1. FUSE-T Binary 發現
|
||||
- ✅ 不是 `/usr/local/bin/fuse-t`
|
||||
- ✅ 實際位置：`/Library/Application Support/fuse-t/bin/go-nfsv4`
|
||||
- ✅ 統一 binary 支援 3種 backend
|
||||
|
||||
### 2. Backend Detection
|
||||
- ✅ macOS 26.4.1 → FSKit (native, fastest)
|
||||
- ✅ macOS <26 → NFSv4 (stable)
|
||||
- ✅ Auto detection working
|
||||
- ✅ Manual selection supported
|
||||
|
||||
### 3. SQLite-backed Operations
|
||||
- ✅ getattr() - file_nodes query
|
||||
- ✅ readdir() - children query
|
||||
- ✅ read() - file_locations query
|
||||
- ✅ Ready for real mount
|
||||
|
||||
### 4. Performance Design
|
||||
- ✅ LRU cache (10,000 entries)
|
||||
- ✅ Write buffer (64KB chunks)
|
||||
- ✅ Target: 600MB/s write throughput

||||
echo "Hello FUSE" > /tmp/test_source/test.txt
|
||||
|
||||
# 2. Mount using MarkBase CLI
|
||||
cargo run -- fuse mount --user test --dir /Volumes/MarkBase_test --backend nfs
|
||||
|
||||
# 3. Verify mount
|
||||
mount | grep MarkBase_test
|
||||
ls /Volumes/MarkBase_test
|
||||
cat /Volumes/MarkBase_test/test.txt
|
||||
|
||||
# 4. Unmount

||||
```
|
||||
|
||||
### Warren User Mount
|
||||
```bash
|
||||
# 1. Mount warren user (12659 nodes)

||||
cargo run -- fuse mount --user warren --dir /Volumes/MarkBase_warren --backend fskit
|
||||
|
||||
# 2. Verify file tree

||||
ls /Volumes/MarkBase_warren | wc -l
|
||||
# Expected: 12659 nodes
|
||||
|
||||

|
||||
find /Volumes/MarkBase_warren -name "*.jpg" | wc -l
|
||||
# Expected: 2371 jpg files
|
||||
