Hi Roland,

I can reproduce your problem.

This helps a little bit:
https://www.pckr.co.uk/arch-grub-mkconfig-lvmetad-failures-inside-chroot-install/

But setting use_lvmeta=0 is not the whole fix.

Make sure the package lvm2 is installed (adding to
package_config/CENTOS)

I guess we have to debug dracut. The kernel command line needs
rd.auto. Using rd.debug, you can enable debug mode to dracut.

Using lsinitrd, you can check if the initrd includes the lvm dracut
module and the executablers for lvm.

I will try to dig deeper into it, if I have some spare time.
