I was trying to extend my LVM fedora partition as there was free space left on my drive. However, I have only ever worked with normal partitions and not with LVM partitions and so something went wrong, leading to Fedora 31 not being able to boot anymore. Instead, after selecting the Fedora 31 Grub boot entry, the Fedora logo and the spinning circle appear but nothing happens. When I hit F3, after a few minutes the dracut-initqueue timeout warning appears. If I then type exit, Fedora 31 boots and I can log in. How can I fix this and how did this happen?
