hi! i managed to install and can successfully start squid when it's using the default cache_dir (/var/spool/squid). but when i changed the cache_dir to a separate partition the squid says it is worked but its not
the /cache/ directory is already owned by the squid user and has 710 permission, just like the permission of /var/cache/squid.

what else could be the problem?
thanks

cache.log says

Hi,

When you define a new cache_dir for squid, you have to use first of all:
to create the new swap directories structure.

Regards

i did and it create the swap directory
but squid is not working
the default is
cache_dir aufs /cache/squid 100 16 256
(16 256)
but i read that 16 must be changed depending on ur hard disk size and i have 2 TB

it is here http://blog.neu.edu.cn/elm/archives/84
and some where else
so if i change 16 to 2000 it will not work but if i put it 16 it will work
whats the problem why i cant change and why it said dirty !!

and after that in cache.log
full of :

16 is the 1st level directories in cache. Better leave it as is. If you want to assign more space for squid cache, increase 100 (that is 100MB) and leave the other values at their defaults. Also better change aufs to ufs, as it's the default storage format.
Then delete everything under the /cache directory and re-run "squid -z" to re-create the cache directory structure

yes you are right i told you when i left it 16 the squid work again
but still have the problem while iam restart it give me

thank you very much

but on another server i can change 16 and it work perfect and it didnt give DIRTY !!

Better start from scratch. Stop squid, delete everything under /cache, recreate the cache (using the -z option) and then start squid normally.
If the problem persists, it could be something else (like a disk problem).


If you start from scratch normally it works. You can change 16, but not to 2000 like in your 1st post. Better take a look here about cache_dir options.

thank you i changed the hdd and it work it give CLEAN now
whats about scratch ?? what it is and what it do ?
i didnt use this in old servers i made !!
and there is any formula to know how much 16 will be every time i increase my hdd size ??
thanks very much

Start from scratch means delete everything you've done and start from the beginning


I don't know of any formula, but you can use google to find out how to optimize squid performance in general

thank you bathory you are gr8 person
