Cache Drive Permission Issues

[JL <zimurgy@xxxxxxxxx>]

Hi,

I am having an issue with my caching drives that I can't seem to pinpoint the problem. I have 4 drives to be used for caching, they are ext3 filesystems mounted like so. I am running CentOS 7.

/dev/sde1 on /var/spool/squid4 type ext3 (rw,noatime,seclabel,data="">

/dev/sdd1 on /var/spool/squid3 type ext3 (rw,noatime,seclabel,data="">

/dev/sdc1 on /var/spool/squid2 type ext3 (rw,noatime,seclabel,data="">

/dev/sdb1 on /var/spool/squid1 type ext3 (rw,noatime,seclabel,data="">

I set the cache user to be squid in the squid.conf and I reference the drives for caching.

cache_dir aufs /var/spool/squid1 460800 32 512

cache_dir aufs /var/spool/squid2 460800 32 512

cache_dir aufs /var/spool/squid3 460800 32 512

cache_dir aufs /var/spool/squid4 460800 32 512

ls -l of the /var/spool shows proper perms, they are propagated.

drwxr-x---. 34 squid squid 4096 Aug 21 10:01 squid1

drwxr-x---. 34 squid squid 4096 Aug 21 10:01 squid2

drwxr-x---. 34 squid squid 4096 Aug 21 10:01 squid3

drwxr-x---. 34 squid squid 4096 Aug 21 10:01 squid4

The cache dirs were successfully created using squid -z and all of the subfolders were generated. Squid starts and everything appears to be great. Until I monitor the cache.log, then I see the errors begin.

Some like this.

The folders remain empty of course, so no caching is taking place.

I am truly stumped as to what I may be doing wrong since squid has enough perms to create the dirs but not enough to save to them.

Any help would be great.

Thanks!

Zim
