I think removing that file should help. What is your cache_dir setting
in /etc/lvm.conf file? You can completely remove that dir. On my
machine, cache_dir is set to /etc/lvm/cache and doing "rm -rf
/etc/lvm/cache" or "rm -f /etc/lvm/cache/.cache" should help.

BTW, the .cache file is just a text file, see what is there.

Thanks, Malahal.
