[ovirt-users] Software RAID installation fails

[Brian Moyer]

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 '/'

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,
