[squid-users] squid cache not updating?

[J Webster]

I have my cache mounted on a drive at /var/spool/squid.
The other day I tied to mount a new folder also on the same drive, which is 
apparently not the best thing to do.
Since then, I am not sure if my squid cache is updating or not. It seems to 
be stuck at 35Gb use and 16% capacity.
Is there anyway to check if the cache is updating?
