So, this is actually a family member's machine and he was using it at
the time so I don't know, firsthand what happened.
He says he was just adding some plugin to some (Windows) program in
Wine. Doesn't seem like that should come anywhere near resizing so I
will ask him again.

I can do that in Fedora's "rescue" environment? Probably "lvm
vgcfgrestore -f back --force brianr-laptop" instead.

I will see if there is anything in the logs and get back to you. It's
the least I can do in return for the help you have provided. Much
