mount failure on ppc64le with NVMe boot drives

[manojnkumar]

Running into this issue on a brand-new ppc64le system, that boots RHEL 8 fine. The boot disk is NVMe.

Usage: /usr/libexec/coreos-installer [options]
Options:
    -d DEVICE   Install to the given device, alternatively specify
                coreos.inst.install_dev on the kcmdline.
    -i IGNITION The URL (or path) to the given Ignition config,
                alternatively specify coreos.inst.ignition_url on the
                kcmdline.
    -b BASEURL  The URL to the image, alternatively specify
                coreos.inst.image_url on the kcmdline.
    -h          This.

This tool installs CoreOS style disk images on a block device.

@cgwalters has recommended that I add:

coreos-installer works fine on the same system with SATA ssd.

[manojnkumar]

The NVMe drives were set to 4k sectors. When I reformatted the drives to 512b sectors, the installer proceeded to completion.

i.e. This issue is the same as: coreos/fedora-coreos-tracker#385

Great, thanks for tracking this down. I'll close as a duplicate of coreos/fedora-coreos-tracker#385.
