I don't think that you need to recreate the cache dirs.
IMHO you would loose the data as you need to remove at least the dir you
want to recreate. You can recreate a single cache_dir, I use a modified
squid.conf (with only one cache_dir) for that.
Erasing a cache_dir take ages. If you need to keep the squid up,
deactivate the cache_dir in squid.conf. Creating a new filesystem is
definitely faster.
There might be another problem. Please post your cache_dir settings.
