Fedora Arm Secondary Architecture/NFS Configuration

Goal

To configure a VM or physical ARM machine to use the NFS share on HongKong (assuming a private network connection).

Steps to Perform

On the ARM machine (VM or hardware device):

1. Edit your "/etc/fstab" and change the following lines file system to "auto" from "nfs":

/dev/root  /  auto  defaults  1 1

2. Use yum to install "rpcbind" and "nfs-utils" and make sure that the "rpcbind" and "nfs" services are started at boot:

yum install rpcbind nfs-utils
chkconfig rpcbind on
chkconfig nfs on

3. Create the /share folder to mount the HongKong NFS share.

mkdir /share

4. Create an /etc/hosts entry for HongKong using both the hostname and the FQDN - chose only one line from the following:

echo "192.168.122.1 hongkong hongkong.proximity.on.ca" >>/etc/hosts  # VMs only
echo "192.168.1.254 hongkong hongkong.proximity.on.ca" >>/etc/hosts  # physical hardware only

5. Create an fstab entry to mount the /share directory from HongKong:

echo "hongkong:/share /share nfs defaults,noauto 0 0" >>/etc/fstab

6. Test that you can successfully mount the share:

mount /share

7. If it mounts correctly it will give no output. Run the "mount" command to check that it has been successful.

8. Add a line to /etc/rc.d/rc.local to mount the share automatically at boot time (note: this will fail if the NFS share is not available at boot, but the boot will proceed. The alternate approach of mounting at boot time via /etc/fstab will cause the boot to stall/fail if the NFS share is not available at boot):

echo "mount /share" >>/etc/rc.d/rc.local

9. Create a link for Koji:

ln -s /share/koji /mnt/koji

9. Optional/recommended: Reboot your vm to make sure the nfs share is properly mounted at boot. To restart your vm log into hongkong as root and run the following commands. As an example i will use arm-001-999, replace this with your VM. First, on the VM:

poweroff

Then on the host (HongKong):

virsh destory arm-001-999
virsh start arm-001-999
