 Hi, I pre-create the storage file using the dd(1).

 Unfortunately, I catch the "Error: (-sfile) size "XXG": larger than file
 system" message at the varnish start.

 And, If storage is full, Varnish can't restart.(specified size > file-
 system space)

 https://github.com/varnish/Varnish-
 Cache/commit/551e0de9e89a83b6b465fc8800dfc9b47217a9dc

 This commit does not care pre-allocation size.

 I think that it is necessary to check the real size.
