More than 100% disk usage is possible !!!



  • Hi !

    With an installation made on June 2007 of 1.2 beta 2, i havec more than 100% of disk usage, with no reboot and no problems …

    
    # cd /
    # df
    Filesystem  1K-blocks    Used   Avail Capacity  Mounted on
    /dev/ad0s1a   1484678 1478042 -112138   108%    /
    devfs               1       1       0   100%    /dev
    /dev/md0         1710      40    1534     3%    /var/run
    devfs               1       1       0   100%    /var/dhcpd/dev
    
    

    I have reboot it, uninstall Squid, delete its directory, reboot again …
    I don't use any package, just Squid ...

    When i reboot, this installation is fully fonctionnal ...

    What do you think about this problem ... ?



  • There is no problem.  See the FreeBSD newfs man page for details on space reserved from normal users, which is by default 8%.  This is the cause of the figures you're seeing having almost filled your root partition (you've got about 6 MB left).



  • I haven't say an important thing … yesterday, i was connected on this firewall for know IP Address of one printer and the disk usage by GUI (index.php) graphic waq about 55-57% ...



  • Your root partition is only 1.5 GB?  That's fine with no packages, but I'd imagine squid will fill that up pretty quickly. It seems it goes away when you uninstall squid, so I think the problem is you don't have enough drive space to run squid.



  • I use 2GB hard drive …
    configured squid for use only 100MB of cache ...

    in two others sites, i use the same config, same version, same hardware ... without this problem ... and i had never use more than 45/50% space on my hard drive.



  • Next time it happens, run the following commands from a shell and paste the output here.

    df -h
    cd / && du -hd1



  • df -h

  • I don't know if it's unusual or not (I only have my own host to compare with), but your /usr/local/www/usr is 106 MB, mine is closer to 200 KB.  Your /sbin is also about twice the size of mine (1.2 Beta2).

    As a reference, I have Squid, FreeRadius, IMspector, NUT, PFFlowed, Snort and LightSquid all installed with 438 MB of disk space in use.  Squid is set to use 128 MB of disk (and memory) for cache.



  • This morning, i perform a succefull test with MAxtor utilities, this evening … the same test return errors ... !

    I think hard drive is death ... but Pfsense can always boot and be used but some service aren't fully fonctionnal such as DHCP server ...

    After reinstall with new HDD ... all is OK, i will compare directory size's for see.



  • 400+ MB in your /tmp is odd. What's in there?  Should be more like a few KB.

    having a /usr/local/www/usr folder is also strange, I'm guessing the squid package must have put that there as that shouldn't be there.

  • Your /var is 17 GB.  Now repeat the du command inside /var.
