[ovirt-users] Software RAID installation fails

When I attempt to install oVirt Node (newest ISO; ovirt-node-ng-installer-ovirt-4.0-2016062412.iso), the installer fails at the very end with the following error if any software RAIDs are defined in storage options. There was an error running the kickstart script at line 7 . This is a fatal error and installation will be aborted. The details of this error are: [INFO] Trying to create a manageable base from '/' Traceback (most recent call last): File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main "__ main __", fname, loader, pkg_name) File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code exec code in run_globals File "/usr/lib/python2.7/site-packages/imgbased/__main__.py", line 42, in <module> CliApplication() File "/usr/lib/ python2.7/site-packages/imgbased/__init__.py", line 80, in CliApplication app.hooks.emit("post -arg -parse", args) File "/usr/lib/python2.7/site-packages/imgbased/hooks.py", line 120, in emit cb(self.context, •args) File "/usr/lib/python2.7/site-packages/imgbased/plugins/core.py", line 167, in post_argparse app.imgbase.init_layout_from(args.source, init_nvr) File "/usr/lib/python2.7/site-packages/imgbased/imgbase.py", line 230, in init_layout_from self.init_tags_ on(existing_lv) File "/usr/lib/python2.7/site-packages/imgbased/imgbase.py", line 217, in init_tags_on pool.addtag(self.thinpool_tag) AttributeError: 'NoneType' object has no attribute 'addtag' This occurs with standard RAID volumes, with an LVM volume defined on top of RAID, and any combination thereof. When the installer is allowed to pick it's own storage scheme, it works fine. All of my testing has been done on blank physical disks or newly created virtual disks. The anaconda and storage logs don't appear to be very useful. Has anyone else come across this? Thoughts on workarounds or where I should be looking next to track down a solution? Thanks, Brian
