The grub2-mkconfig does not propagate renamed root logical volume on RHEL 9

On the RHEL 9.3 I have renamed the logical volume (LV) /dev/lvm01/root to /dev/lvm01/root.vol. I did everything to make the new name correctly recognized: - changed /etc/fstab entry - reloaded systemd configuration - remounted / And I also modified the /etc/default/grub entry: GRUB_CMDLINE_LINUX="root=/dev/mapper/lvm01-root.vol ro crashkernel=1G-4G:192M,4G-64G:256M,64G-:512M resume=/dev/mapper/lvm01-swap.vol rd.lvm.lv=lvm01/root.vol rd.lvm.lv=lvm01/swap.vol" Then I expected the grub2-mkconfig -o /boot/grub2/grub.cfg to do the rest of the job and rebooted. But the system ended up with dracut message that the root partition is not found (or something like that). After short investigation, I realized the kernel parameters had not been modified as expected. The manual change helped to get the OS booted. Interesting that the /boot/grub2/grub.cfg was updated. But what was not updated was the /boot/loader/entries/* files. And it was the issue.
