Run “luaotfload-tool --help”. Near the end it should print the
cache paths, e.g.:

    The font database will be saved to

    <snip />
    The font cache will be written to

The path prefix (configured in texmf.cnf; in this case
/home/phg/src/texlive2013/) must be writable for the user that is
running luatex; the subdirectories under it will be created, even
if you only run luaotfload-tool without options.

According to your log file that is where the font loader writes
its cache files to:


The names db should reside in a subdirectory “/names”, the font
cache under “/fonts/”. If deleted, it will be recreated the next
time you run luaotfload-tool or luatex with luaotload. Can you
post the permissions of these directories and the files in them?
