Description of problem: When adding external lun to a VM I can choose luns that are part of an existing storage domain. My storage domain build on top of 2 FC luns, while getting the luns list to add as external to a VM, both can be selected. Very problematic as it can lead to Data corruption Version-Release number of selected component (if applicable): 3.5 How reproducible: 100% Steps to Reproduce: 1. Create storage domain based on 2 FC luns 2. Create VM with a virtual disk 3. add external lun to this VM Actual results: In the list of luns to add, we can choose the storage domain luns as well Expected results: both luns should be greyed out. Additional info: appear in our rhevm-3 setup, Can share access for analysis if needed.
The ability itself is by design - it's the basis for CFME's fleecing capabilities. I agree it's ugly that this is also exposed in the GUI, but there's nothing urgent about it. Reducing severity and removing z-stream flag. Not sure if changing the GUI is the right call though - there is merit in keeping GUI and REST aligned. Leaving this up to PM to decide.
Scott/Yaniv, your thoughts?
(In reply to Tal Nisan from comment #2) > Scott/Yaniv, your thoughts? We will not block a ability that is needed for cloudforms. We can add a warning on doing this to make sure users really want to do things that might lead to corruption.
