Changing the size of a cache_dir

Hi,

I made a cache_dir too small and want to increase it. I changed the size
and restarted the machine (I was rebooting it anyway) - it worked fine.

However, when I came in this morning, the size reverted back down again
(I am checking the size using the cachemgr).

What should I do if I want to change the size of a cache_dir? Recreate
the Squid object directories (i.e. 'squid -z')? One of the cache_dirs
I'm changing is the first of the collection.

As an aside, does Squid consider filesystem space, or just the configured
cache_dir space (i.e. if I put 10000 in cache_dir but the filesystem is
only 9500, will Squid keep trying to fill the partition?).

Thanks,

  - Bob
