<title>Adding Primary Storage to a KVM hypervisor</title>
|
|
<para>For most Primary Storages there are no special requirements to add primary storage,
|
|
it's all done via the management server.</para>
|
|
<para>The follow subchapters however describe a couple of prerequisites for adding primary storage to a KVM cluster/hypervisor.</para>

<section id="hypervisor-host-install-primary-storage-nfs">

<title>Requirements for NFS primary storage</title>
|
|
<para>&PRODUCT; will handle the mounting of the NFS storage, no manual intervention is required.</para>
|
|
<para>Before adding the Primary Storage make sure the NFS client packages are installed. It's always useful to do a manual mount on one or
|
|
more hypervisors prior to adding the primary storage to make sure the mountpoint works.</para>

|
|
<title>Requirements for iSCSI primary storage</title>
|
|
<para>When adding iSCSI Primary Storage the management server of &PRODUCT; will configure the iSCSI initiator. The requirement however is that
|
|
Open-iSCSI is installed on all hypervisors.</para>

<section id="hypervisor-host-install-primary-storage-ceph">
|
|
<title>Requirements for Ceph primary storage</title>
|
|
<para>Support for RBD Primary Storage was added in &PRODUCT; 4.0 and requires a special version of libvirt.</para>
|
|
<para>With the KVM hypervisor &PRODUCT; relies on libvirt for handling it's storage pools. Most versions of libvirt
|
|
don't have the RBD storage pool support yet, so a manual compile of libvirt is required.</para>
|
|
<para>To use RBD primary storage make sure you hypervisors meet the following requirements</para>
|
|
<itemizedlist>
|
|
<listitem><para>Make sure librbd is installed on your system.</para></listitem>
|
|
<listitem><para>A RBD-enabled Qemu version is installed</para></listitem>
|
|
<listitem><para>Libivrt (>= 0.9.13) with RBD storage pool support enabled is installed</para></listitem>
|
|
<listitem><para>No /etc/ceph/ceph.conf configuration file is present on your hypervisors.</para></listitem>
|
|
</itemizedlist>
|
|
<para>After meeting these requirements you can add the RBD storage pool via the WebUI.</para>
|
|
<para>Hint: Ubuntu 13.04 meets all these requirements by default.</para>
|
|
<note><para>&PRODUCT; doesn't support multiple hostnames when adding a Primary Storage pool. If you have multiple Ceph monitor daemons
|
|
it's best to create a Round Robin-DNS record and use that as the hostname for the storage pool.</para></note>
