Problem:

Mounting NFS share under XEN environment

Symptoms:

Following the mount of NFS share under XEN environment the share is not available

Solution:

In order for the NFS share to be available after mounting it, the following parameters are required for XEN:

1. CLI mount: "-o tcp,hard,intr"

2. XEN GUI: "tcp,hard,intr" [-o should be discarded]

"tcp" option informs the system to use the TCP protocol
"hard" mount is generally used for block resources like a local disk or SAN
intr If "hard" is specified, the user cannot terminate the process waiting for NFS communication to resume, unless the "intr" is also specified. "intr" allows NFS requests to be interrupted if the server goes down or cannot be reached
