Just for reference (since my original post has been removed in the
replis) the cache_dir lines from my squid.conf are:
cache_dir ufs /cache/squid 6856 16 256
cache_dir ufs /var/spool/squid 1000 16 256
Both filesystems are ext3. Here's the info from /proc/mounts:
$ cat /proc/mounts | grep -E '(cache|var)'
/dev/sda1 /cache ext3 rw 0 0
/dev/hda5 /var ext3 rw 0 0
Other than being on different drives, they look the same to me. The SCSI
drive (sda) was added to the system specifically to hold the squid
cache. The drive works fine and i can read and write files to it
without problems.
Also, both partitions do have plenty of free space:
$ df -h /cache /var
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 8.4G 68M 7.9G 1% /cache
/dev/hda5 3.9G 270M 3.4G 8% /var
Any ideas?
Just for the heck of it, i changed the cache_dir lines to:
cache_dir ufs /usr/squid 1000 16 256
cache_dir ufs /var/spool/squid 1000 16 256
Some stats on /usr:
$ cat /proc/mounts | grep usr
/dev/hda3 /usr ext3 rw 0 0
$ df -h /usr
Filesystem Size Used Avail Use% Mounted on
/dev/hda3 3.9G 654M 3.1G 18% /usr
So, like /var and /cache, /usr is ext3 and has plenty of free space. I
created the directory /usr/squid and set permissions:
$ ls -ld /usr/squid
drwxr-xr-x 18 squid squid 4096 Oct 25 16:57 /usr/squid
Running "squid -z" created all the subdirectories as one would expect:
$ ls -l /usr/squid
total 128
drwxr-xr-x 258 squid squid 4096 Oct 25 16:57 00
drwxr-xr-x 258 squid squid 4096 Oct 25 16:57 01

But when i start Squid i still get lots of errors:

I tried creating swap.state and swap.state.last-clean, since both files
exist in /var/spool/squid:
# ls -l /usr/squid/swap.state*
-rw-r--r-- 1 squid squid 0 Oct 25 17:15 /usr/squid/swap.state
-rw-r--r-- 1 squid squid 0 Oct 25
17:17 /usr/squid/swap.state.last-clean
When attempting to restart Squid, i still get the error:
2005/10/25 17:17:28| /usr/squid/swap.state: (13) Permission denied
Weird. As far as i can tell, Squid has permission to read and write the
necessary files, but still says permission denied...
