BTW:
S_Haran on Reddit suggested that given I have /etc/lvm/backup
I should be able to use and I quote:
"
When a logical volume is created a copy of the config is kept in the
OS volume (possibly /dev/md1) in /etc/lvm under subfolder name backup
or archive. If you can find the config file then you can use it with
command vgcfgrestore to bring the PV /dev/md3 back to life.

I've asked him to explain the process. Hopefully he will sometime tomorrow.
