Maybe you could reinitialize initramfs with dracut -f --regenerate-all if i'm not mistaken? You can do that with safe mode,or ISO.

what can we do?
centos7 rescue did not find any disk.
we move the disk to qcow2 format and mount it from the proxmox host (/var/liv/vz/....)...partitions are there and data are there.

ok we change the type of SCSI Controler to LS and back to VirtIO, now with rescue boot we can do
vgchange -ay
but it says refusing activation of partial LV centos/root

reboot centos7 normal still hung on dracut with
/dev/centos/root not found

we got it:
we do
vgextend --restoremissing <volume group> <physical volume>
this works.
confusing because lvdisplay shows no missing PV
