Experimental NFSv4 server library in pure go.
The motive I started this project is mainly I need to immigrate a few projects to k8s and there are no other storage services except an OSS(like aws s3). So I need something to join OSS and k8s PV together. To me NFS is a interesting choice.
Currently this repo doesn't include any COS wrapper in it.
To give it a try:
package main
import (
"fmt"
"os"
"github.com/smallfz/libnfs-go/backend"
"github.com/smallfz/libnfs-go/memfs"
"github.com/smallfz/libnfs-go/server"
)
func main() {
mfs := memfs.NewMemFS()
backend := backend.New(mfs)
mfs.MkdirAll("/test", os.FileMode(0755))
mfs.MkdirAll("/test2", os.FileMode(0755))
mfs.MkdirAll("/many", os.FileMode(0755))
perm := os.FileMode(0755)
for i := 0; i < 256; i++ {
mfs.MkdirAll(fmt.Sprintf("/many/sub-%d", i+1), perm)
}
// TODO: replace the in-memory backend with your own implementation.
// ....
svr, err := server.NewServerTCP(":2049", backend)
if err != nil {
fmt.Printf("server.NewServerTCP: %v"\n, err)
return
}
if err := svr.Serve(); err != nil {
fmt.Printf("svr.Serve: %v\n", err)
}
}
After the server started you can mount the in-memory filesystem to local:
on Mac:
mount -o nfsvers=4,noacl,tcp -t nfs localhost:/ /Users/smallfz/mnt
on Linux:
mount -o nfsvers=4,minorversion=0,noacl,tcp -t nfs localhost:/ /mnt
Recent testing results of nfstest_posix with --nfsversion=4

Firing an issue if anything. Any advice is appreciated.
