    Hi, I followed these steps from this tutorial (Smartmontools): http://www.howtoforge.com/checking-hard-disk-sanity-with-smartmontools-debian-ubuntu

    ..as I have also followed the ISPConfig 3 on Debian Wheezy tutorial, on the 2nd page here http://www.howtoforge.com/perfect-server-debian-wheezy-apache2-bind-dovecot-ispconfig-3-p2

    .. I have used what you do in the tutorial as well: 'Guided - use entire disk and set up LVM'

    So when I do fdisk -l
    I get this:
    Code:
    [email protected]:~# fdisk -l

    [email protected]:~#
    
    I noticed the:
    Code:
    Disk /dev/mapper/debian-root doesn't contain a valid partition table
    
    and
    Code:
    Disk /dev/mapper/debian-swap_1 doesn't contain a valid partition table
    
    ..messages and checked on the net (as this is a 3 days old HD) and someone said that 'fdisk does not understand LVM content'.

    What is your advice, how should I check my hard drive in order to make sure everything is ok ? I would go in trouble installing this drive on a windows machine only to check it using some apps I got there :)

    Now the output of smartctl -a /dev/sda is this and I think is ok ? (note: this is on a Pentium 4 i386 PC so some features of the HD may be down):
    Code:
    [email protected]:~# smartctl -a /dev/sda

    By the way, on a production server setup would you recommend 'Guided - use entire disk and set up LVM' or to use a secondary drive or partition for the websites ? What are the pros and cons ? I always preferred the pure data on a separate drive but I never tried this with ISPConfig, but I got all the time to test it. I just would like your recommendation.

    Nice tutorial on Smartmontools, somewhere near the end you give two examples. One is:
    Code:
    DEVICESCAN -m root -M exec /usr/share/smartmontools/smartd-runner
    and the other is:
    Code:
    /dev/hda  -m [email protected] -M exec /usr/share/smartmontools/smartd-runner
    I guess one should not use both in the /etc/smartd.conf file right ?

    thanks in advance
    have a nice day

    Correct, in case of DEVICESCAN, the specific drive lines in the config file are ignored.
