Ok, so you need to manually edit your volume group config as well;
De-activate LV’s;
lvchange -an qubes_dom0
Backup metadata;
vgcfgbackup qubes_dom0 -f /etc/lvm/backup/qubes_dom0
Edit your backup config file - search for transaction ID number and replace with correct ID, eg. change 21472 to 21471 and save;
sudo nano /etc/lvm/backup/qubes_dom0
Restore edited metadata;
vgcfgrestore --force qubes_dom0 -f /etc/lvm/backup/qubes_dom0
Reactivate LV’s;
lvchange -ay qubes_dom0
Use lvscan to check if LV’s are now all ACTIVE. If they are, reboot and qubesd should load normally.
