RE: Squid unreachable every hour and 6 minutes.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It's nearly what I already tried.

(1) Ok
(2) I had : cache_dir ufs /cache 5000 16 256
(3) mke2fs -j -c /dev/cciss/c0d0p6      (/dev/cciss/c0d0p6 is my Cache partition)
(3) ok
(4) /etc/init.d squid start.


The effect was exactly the same : squid stop every hour.

So I tried :

(2) changed : cache_dir ufs /cache 100 16 256
(4) squid -k reconfigure

Same result.

Then a last sing I did :
(1) Stop Squid
(3) cd /cache
    rm cache.swap
(4) Start Squid

And again ... Same result.


But as the server is in production, I wll try tonight to delete folder as you propose,.... 

Thanks.

L.G.

Subject: AW:  Squid unreachable every hour and 6 minutes.

Please repeat that again.

(1) stop squid

(2) find out wht are the cache directories squid uses, for example

       # grep cache_dir squid.conf
       cache_dir ufs      /data1/squid_cache 6000 32 512
       cache_dir ufs      /data2/squid_cache 10000 32 512
       #

     In this example /data1/squid_cache and /data2/squid_cache are the cache dirs.

(3) Clean all cache dirs - in this example:

       cd /data1/squid_cache
       rm -f *
       cd /data2/squid_cache
       rm -f *

(3) create the cache structures again:   squid -z

(4) Start squid.
    What happens?
    Is squid running?     ps -ef | grep squid
    What does cache.log say since starting of squid?
    Is squid reachable?

(5) What happens after 1 hour an 6 minutes?
