NFS Export Setup Guide for Ubuntu EC2

Start an Ubuntu EC2 instance and check the security group to make sure that the NFS port on this server is open for connection from your NFS client servers.

Install NFS server.

$ sudo apt-get install nfs-kernel-server

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

$ sudo mount.objectivefs <your filesystem> /ofs

In /etc/exports, add the following line where directory is the directory you would like to share and ip address is the ip address of the NFS client machines.

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

Example to allow the NFS client at 10.0.0.100 to mount /ofs:

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

In /etc/default/nfs-kernel-server, increase the number of threads on the NFS server.

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
