Currently, these path must be on the same volume, because nginx just
link() to new place without copying. However, I plan to fallback
to copy temp file to another temporarily file on proxy_cache_path
voulme and then link() it to permanent name. As current workaround
you may set special proxy_temp_path for some locaitons only:

http {

     proxy_cache_path   /vol1/cache ...
     proxy_temp_path    /vol2/temp;

     server {

         location / {
             proxy_cache  ...
             proxy_temp_path    /vol1/temp;
