setting varnish storage size

[jean-marc pouchoulon]

Hi ,
I'm a bit confused  about /var/lib/varnish/varnish_storage.bin
I use varnish 1.0.0.4 under linux fedora 6 ( using a vserver ).

I set in /etc/sysconfig varnish VARNISH_STORAGE_SIZE=2G
and the size of the file still remains to one GIGA

 -rw------- 1 root root 1,0G jun 29 19:27 
/var/lib/varnish/varnish_storage.bin

setting  VARNISH_STORAGE_SIZE=2000G /var/lib/varnish/varnish_storage.bin


setting 3000G I get
-rw------- 1 root root 1,5G jun 29 19:29 
/var/lib/varnish/varnish_storage.bin

mm what I don't understand ? ( the % parameter ?)

thanks
