Re: Cache Permission Errors

Hi Xen,
Thanks for the feedback. I can confirm both the --with-default-user=squid is present in squid -v and the perms of the logs are indeed squid user.

Regards,
Zim

    Are you terribly certain the owner:group of the generated log files

    That is a way to check for sure what user it is running under. I was
    just compiling the latest 3.5.x when it would complain, and I had
    forgotten to compile it with --with-default-user=squid.

        Hi, 

        Sorry if this is a duplicate message, I am not sure it went
          through initially. 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
