Red Hat Bugzilla – Bug 611823
Storage driver should prohibit pools with duplicate underlying storage
Last modified: 2012-06-20 02:23:39 EDT
+++ This bug was initially created as a clone of Bug #547431 +++ Description of problem: libvirt allows a user to create two pools with exactly the same underlying storage. The simplest example is two directory pools that point to the same directory, but iSCSI and other pool types behave similarly. The result is that libvirt can have a pool with an inconsistent view of its volumes if the other pool has been used to issue the volume modification operation. For example, if two directory pools point to the same directory, and one pool is used to create a volume, the other pool will remain unaware of the new volume until it is refreshed. Version-Release number of selected component (if applicable): libvirt-0.6.3-24 How reproducible: 100% Steps to Reproduce: 1. Create a directory pool pointing to a given directory 2. Create a second pool pointing to the same directory Actual results: Two pools will be created. Expected results: The second pool should be rejected. Additional info:
Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as an exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.
commit 5a1f2728754a7b7bea4efd245d7171ab6286d681 Author: Lei Li <lilei@linux.vnet.ibm.com> Date: Mon Sep 5 15:52:03 2011 +0800 Check for source conflicts in storage pools Fix bug #611823 storage driver should prohibit pools with duplicate underlying storage. Add internal API virStoragePoolSourceFindDuplicate() to do uniqueness check based on source location infomation for pool type. * AUTHORS: add Lei Li Patch is in upstream.
I can reproduce this bug with libvirt-0.8.7-18.el6_1.3.x86_64 can create two directory pools point to the same directory. verify on libvirt-0.9.9-1.el6.x86_64 step: # virsh pool-list --all Name State Autostart ----------------------------------------- default active yes dir active yes testiqn active yes # virsh pool-dumpxml dir > dir.xml # vim dir.xml change pool name and UUID in xml file,but don't change path # virsh pool-define dir.xml error: Failed to define pool from dir.xml error: operation failed: Storage source conflict with pool: 'dir' The second pool is rejected. verification passed. move to verified.
