Re: [squid-users] squid error storeAufsOpenDone: (1) Operation not permitted

Hi,

I got such errors when I changed "cache_dir" parameters in squid.conf.
It's because the old directory tree isn't suitable for new parameters,
and as result
some objects aren't cached.

After reinit of cache directory (delete and recreate with squid -z)
the errors disappeared.
