I am running Squid Version 2.6.STABLE5 on CentOS 4.2. Squid is
configured with two cache directories /asc/array1/squid/var/cache and
/asc/array2/squid/var/cache. Logs are configured to write to the
default location /usr/local/squid/var/logs. Here are snippets of
squid.conf:
#Default:
# cache_dir ufs /usr/local/squid/var/cache 100 16 256
cache_dir ufs /asc/array1/squid/var/cache/ 600000 16 256
#cache_dir ufs /asc/array2/squid/var/cache/ 600000 16 256
#cache_dir ufs /asc/array3/squid/var/cache/ 600000 16 256
--the 600000 was 800000. I decreased the value and ran #/squid -z to
try and resize the cache. I did not see any change.
...
# To log the request via syslog specify a filepath of "syslog"
access_log /usr/local/squid/var/logs/access.log combined
...
#Default:
cache_log /usr/local/squid/var/logs/cache.log
...
#Default:
cache_store_log /usr/local/squid/var/logs/store.log
...
Squid has shut down with the following error:
2006/12/27 11:27:04| Rebuilding storage in /asc/array1/squid/var/cache/

Squid Cache (Version 2.6.STABLE5): Terminated abnormally.

Here is the space left on the server:

/dev/sda1 101G 89G 7.4G 93% /asc/array1
/dev/sdb1 101G 96G 0 100% /asc/array2
/dev/sdc1 101G 93M 96G 1% /asc/array3
In order to get Squid working again, I have shut down /asc/array2 as a
cache drive. However, this leaves me with 7.4GB available on the other
cache drive and I am afraid it will run out of space quickly.
So, two questions, why am I running out of space. Are there other logs
going to the cache drives that I don't know about? Second, can I shrink
the size of the cache? Other than taking down Squid for a few moments,
will it do anything else bad? How bad would it be if I were to
completely wipe out the cache directories and rebuild them from scratch?
Thanks in advance for any help you can give.
