DIB: unable to build overcloud-hardened-uefi-full image

[Cédric Jeanneret]

Hello there,

While trying to build the mentioned image, I hit an issue with lvm and the loop device (see bellow for the extracted data, and attachment for the full log).

Apparently, it's able to create the volume-group, but then fails to create the logical volume. I'm still investigating the actual error reported by the "exec_sudo" ("/dev/vg/lv_root: not found: device not cleared") - but I've never seen this issue so far.

Notes:
- I'm building from within a privileged container (launched as root)
- I don't see any SELinux denials at the time of the build

I'm still investigating, but since I'm also hitting another issue[1], it's taking some more time...

This is likely the cause. See my comment in #1959093
