I have been searching all day but have not found a solution for this.
My laptops power cord got chewed up by my dog and while I was waiting for a new one to arrive I had to access some files from my laptop drive.
I removed the drive and plugged it into my desktop, however since I was also running Fedora on the Desktop I had to run a series of commands to mount the appropriate drive and access the desired files. I do not recall the specific sequence of commands and one of them was mklabel
Upon receiving the new power cable and booting my laptop I now get
Warning: /dev/fedora/root does not exist
Warning /dev/fedora/swap does not exist
Warning : /dev/mapper/fedora-root does not exist
How do I fix this issue? I have tried booting a live disk and runningdracut --regenerate-all -f && grub2-mkconfig -o /boot/grub2/grub.cfg
but it has not helped.
Any advice would be greatly appreciated!!

Check the output:
sudo vgs; sudo pvs; sudo lvs; lsblk -o +FSTYPE,UUID
OK - what am I looking for with regard to this?
The one thing that jumps out at me is that the swap partition has FSTYPE of swsuspend
[liveuser@localhost-live ~]$ sudo lvm lvscan

It looks like your VG name is not fedora, but fedora_laptop.vgrename, or use the correct name.
Note that if you decide to rename the VG, you should update /etc/default/grub and /etc/fstab accordingly, and then run under chroot :
sudo grub2-mkconfig -o /etc/grub2$(test -d /sys/firmware/efi && echo -efi).cfg
sudo dracut -f --regenerate-all

Thank you so much - renaming the volume group worked perfectly
