Exporting ObjectiveFS to Windows via NFS

Mount your objectivefs filesystem (e.g. on /ofs).

$ sudo mount.objectivefs <your filesystem> /ofs

Install NFS server.

$ sudo apt-get install nfs-kernel-server

$ sudo yum install nfs-utils

In /etc/exports, add the following line where ip address is the windows machine's ip address.

/ofs  <ip addr>(rw,fsid=<unique id>,no_subtree_check,mp,async)

Example to connect to a windows NFS client at 10.0.0.100:

/ofs  10.0.0.100(rw,fsid=222,no_subtree_check,mp,async)

Increase the number of threads on the NFS server.

Ubuntu: In /etc/default/nfs-kernel-server

RPCNFSDCOUNT=<number of threads>  # e.g. 64

Red Hat/CentOS: In /etc/sysconfig/nfs

RPCNFSDCOUNT=<number of threads>  # e.g. 64

Restart the service.

$ sudo service nfs-kernel-server restart
$ sudo service idmapd restart  # you may also need to restart idmap

$ sudo /etc/init.d/nfs restart

Verify that the Linux server's NFS port is open for connection from the Windows server.

Setup client for NFS.

Start
→ Server Manager
→ Manage (top right menu)
→ Add Roles
→ Select "Role-based or feature-based installation"
→ Select the current server
→ In "Server Roles", click next
→ In "Features", select "client for NFS" and click next
→ Click "Install" to confirm the installation

A registry addition is required to have read/write access to NFS shared from a Windows system. By default, the anonymous UID and GID for Client for NFS is set to -2. You can set this value to 0 or to the user/group id of your choice.

Run "regedit" from the command line
→ Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS
        \CurrentVersion\Default
→ Add two DWORD 32bit values: AnonymousUid and AnonymousGid
→ Set theses values to: 0 (or the uid/gid of your choice)
→ Restart the Client for NFS service or the Windows Virtual Machine

Mount the share from command prompt.

The hard mount option will make nfs retry instead of timing out.

mount -o mtype=hard <NFS_Server_IP>:<Share_Path> <Mount_Point>

example: to connect to a linux server exporting NFS at ip address 10.0.0.123

mount -o mtype=hard 10.0.0.123:/ofs *

Verify your mount options, i.e. that UID=0 and GID=0 and mount type is hard, by typing mount in the command prompt window.
