<title>Using the Management Server As the NFS Server</title>
|
|
<para>This section tells how to set up NFS shares for primary and secondary storage on the same node with the Management Server.
|
|
This is more typical of a trial installation, but is technically possible in a larger deployment.
|
|
It is assumed that you will have less than 16TB of storage on the host.</para>
|
|
<para>The exact commands for the following steps may vary depending on your operating system version.</para>
|
|
<orderedlist>
|
|
<listitem><para>On the Management Server host, create two directories that you will use for primary and secondary storage. For example:</para>
|
|
<programlisting>
|
|
# mkdir -p /export/primary
|
|
# mkdir -p /export/secondary
|
|
</programlisting>
|
|
</listitem>
|
|
<listitem><para>To configure the new directories as NFS exports, edit /etc/exports. Export the NFS share(s) with rw,async,no_root_squash. For example:</para>
|
|
<programlisting># vi /etc/exports</programlisting>
|
|
<para>Insert the following line.</para>
|

<programlisting>/export *(rw,async,no_root_squash)</programlisting>
