Mounting NFS Share using pathfs.LoopbackFileSystem

[imnaveed]

Hi Dear,

I can mount local folder using "FileSystem: pathfs.NewLoopbackFileSystem("/mnt/local")" and can do listing and all other operations; but I can't mount an NFS Share (/home directory) using: "FileSystem: pathfs.NewLoopbackFileSystem("192.168.1.7:/home")".

What could I be missing here? Remember, I can mount NFS Share using normal NFS Client.

code snippet:

---

//nfsRoot := "192.168.1.7:/home"
nfsRoot := "/tmp/nvd"
mountPoint := "/mnt/storage/1"

os.MkdirAll(mountPoint, 0777)
cffs := fs.NewCFFileSystem(nfsRoot)

vfs := pathfs.NewPathNodeFs(cffs, nil)
vfs.SetDebug(false)
conn := nodefs.NewFileSystemConnector(vfs.Root(), nil)

mOpts := fuse.MountOptions{
AllowOther: true,
RememberInodes: true,
}

server, err := fuse.NewServer(conn.RawFS(), mountPoint, &mOpts)
if err != nil {
log.Fatalf("Mount fail: %v\n", err)
}
log.Println("start server")

server.Serve()

Looking forward to your response...

what happens if you do:

ls 192.168.1.7:/home

?

$ ls 192.168.1.102:/home
ls: cannot access 192.168.1.102:/home: No such file or directory

I've exported NFS directories from Server following article below:
https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nfs-mount-on-ubuntu-14-04

I can mount in a standard way; like on client machine I can mount it like this:
sudo mount 192.168.1.102:/home /mnt/nfs/home
and I can do listing and all other stuff... More-over I can run go-fuse loopback on already mounted directory like:

bfs := pathfs.NewLoopbackFileSystem("/mnt/nfs/home")
and it also does work well.

But I can't mount remote NFS directory directly; I'm trying to do it like:
bfs := pathfs.NewLoopbackFileSystem("192.168.1.102:/home") - which of course is not a good way to do it.

So what can be I missing above; or is it possible to mount it directly using go-fuse; or I first have to mount in explicitly and then loopback over already mounted directory though this doesn't makes sense to me; please guide...

• Thanks

you have to mount explicitly first, or write your own NFS client in Go (which is a lot of work).

alright,

Thanks for your help!
