Re: [squid-users] assertion failed in COSS

Hi Amos,

I already have other aufs disks in my configuration :

here is my full cache_dir config file : (i have cache_dir(s) is a
separate config file)

in fact , I have another system (Dell PE R510 4x300GB 15K SAS 24GB
RAM) and it is running just fine with 10 COSS files (50 GB each) and a
bunch of AUFS directories.
