I used these guides for installing NFSv4 [1] and [2].

Contents

NFS File server installation

The storage servers nfs1 and nfs2 acts as NFS file servers. The NFS server software has been installed on these machines.

Here is how the storage and compute servers has been configured.


Create mount points for NFS directories on all servers:

sudo mkdir /image
sudo mkdir /image/data1
sudo mkdir /image/data2
sudo mkdir /image/data3

STATUS: Has been done on all except nfs1

On nfs2 do the following:

sudo mkdir /image/users
sudo mount --bind /home/SCIENCE /image/users

Mounting disks locally

nfs1

In /etc/fstab add

/dev/mapper/vg0-user_1            /image/data2     xfs   defaults        1 2
/dev/mapper/vg1-user_2            /image/data3     xfs   defaults        1 2

nfs2

In /etc/fstab add

/dev/mapper/vg0-user_1             /image/users     xfs   defaults        1 2
/dev/mapper/vg1-user_2             /image/data1     xfs   defaults        1 2
/home/SCIENCE               /image/users    none    bind  0  0

Setting up NFS server

Using YaST2 gui tool for the installation:

sudo /sbin/yast2

Select NFSv4 and open the firewall.

Select Network services->NFS server and configure it with (configured in /etc/exports):

On nfs1-diku-image.science.ku.dk:

/image   *(fsid=0,crossmnt,rw,no_root_squash,sync,no_subtree_check)
/image/data2    *(rw,no_root_squash,sync,no_subtree_check)
/image/data3    *(rw,no_root_squash,sync,no_subtree_check)

On nfs2-diku-image.science.ku.dk:

/image   *(fsid=0,crossmnt,rw,no_root_squash,sync,no_subtree_check)
/image/users    *(rw,no_root_squash,sync,no_subtree_check)
/image/data1    *(rw,no_root_squash,sync,no_subtree_check)

NFS client installation on compute servers

Using YaST2 gui tool for the installation:

sudo /sbin/yast2

Select Network services->NFS client and configure it with (configured in /etc/fstab):

nfs2-diku-image.science.ku.dk:/users      /home           nfs4    defaults 0 0
nfs2-diku-image.science.ku.dk:/data1      /image/data1    nfs4    defaults 0 0
nfs1-diku-image.science.ku.dk:/data2      /image/data2    nfs4    defaults 0 0
nfs1-diku-image.science.ku.dk:/data3      /image/data3    nfs4    defaults 0 0
