mod_cache_disk define max disk usage

Question

I'm using mod_cache_disk to cache some data via apache, I have a 150gb avaiable but mod_cache_disk is only caching 2gb.

I couldn't find a directive that explicit the disk usage, how can I do this? My current configuration is:

   CacheEnable disk /dash/
   CacheRoot "/var/cache/hls_cache"
   CacheDirLevels 5
   CacheDirLength 4
   CacheIgnoreCacheControl on
   CacheMaxExpire 86400
   CacheIgnoreQueryString on

Answer 1

I found out that there isn't such directive however there is a tool called htcacheclean that performs what I want to do.
