Thanks Nichols It worked , I stoped the service and then did squid -z now in my squid.conf I have " cache_dir aufs /opt/var/spool/squid 570000 32 256" I have one doubt, The file type you have advices is 'aufs' while in the sample configuration it is given 'ufs' , should I keeot 'aufs' or 'ufs' Your advice and email is much appreciated Thanks Joseph John ----- Original Message ----- From: Squidblacklist <webmaster@xxxxxxxxxxxxxxxxxx> To: squid-users@xxxxxxxxxxxxxxx Cc: John Joseph <jjk_saji@xxxxxxxxx> Sent: Thursday, 21 March 2013 10:11 AM Subject: Re: cache_dir sapce has 600GB free space then also I get message "WARNING cache_mem is larger than total disk cache space!" Try this instead cache_dir aufs /opt/var/spool/squid 570000 32 256 then do squid3 -z rebuild the cache, reload squid.
