Red Hat Summit3.8. Example: Create NFS Data Storage
An NFS data storage domain is an exported NFS share attached to a data center and provides storage for virtualized guest images. Creation of a new storage domain requires a
POST request, with the storage domain representation included, sent to the URL of the storage domain collection.
In Red Hat Enterprise Virtualization 3.6 and later you can enable the wipe after delete option by default on the storage domain. To configure this specify
<wipe_after_delete> in the POST request. This option can be edited after the domain is created, but doing so will not change the wipe after delete property of disks that already exist.
Example 3.8. Create an NFS data storage domain
Request:
POST /api/storagedomains HTTP/1.1
Accept: application/xml
Content-type: application/xml
<storage_domain>
<name>data1</name>
<type>data</type>
<storage>
<type>nfs</type>
<address>192.168.0.10</address>
<path>/data1</path>
</storage>
<host>
<name>hypervisor</name>
</host>
</storage_domain>
cURL command:
# curl -X POST -H "Accept: application/xml" -H "Content-Type: application/xml" \
-u [USER:PASS] --cacert [CERT] \
-d "<storage_domain><name>data1</name><type>data</type> \
<storage><type>nfs</type><address>192.168.0.10</address> \
<path>/data1</path></storage> \
<host><name>hypervisor</name></host></storage_domain>" \
https://[RHEVM Host]:443/api/storagedomains
The API creates a NFS data storage domain called
data1 with an export path of 192.168.0.10:/data1 and sets access to the storage domain through the hypervisor host. The API also returns the following representation of the newly created storage domain resource.
Result:
