Description Idan Shaby 2014-09-30 08:46:24 UTC

+++ This bug was initially created as a clone of Bug #1147861 +++

Description of problem:
When trying to export a LUN disk in the REST API, a "500 Internal Server Error" is returned.

Version-Release number of selected component (if applicable):
4792bd921cd73b01a990065607561c4ad2b2c486

How reproducible:
100%

Steps to Reproduce:
1. Create an external disk.
1. From the REST API, run a POST request with the next pattern:

URL
http://localhost:8080/api/disks/<DISK_ID>/export

BODY:
<action>
    <storage_domain id="<ANY_STORAGE_DOMAIN_ID>"/>
</action>


Actual results:
A "500 Internal Server Error" is returned.

Expected results:
An informative error message should be returned, or maybe we should even remove the export option for LUN disks in the REST API.
