    Pada server Nagios (Wheezy):

  1. Install pakej-pakej yang diperlukan:
    apt-get install nagios3 nagios-plugins nagios-nrpe-plugin
  2. Buatkan fail /etc/nagios3/conf.d/dns-mylab.cfg seperti berikut:
    define host{
            use                     generic-host            
            host_name               dns
            alias                   dns-mylab
            address                 192.168.1.102
            }
    define service{
            use                     generic-service
            host_name               dns
            service_description     Current Load
            check_command           check_nrpe_1arg!check_load
    }
    define service{
            use                     generic-service
            host_name               dns
            service_description     Current Users
            check_command           check_nrpe_1arg!check_users
    }
    define service{
            use                     generic-service
            host_name               dns
            service_description     Disk Space
            check_command           check_nrpe_1arg!check_root
    }
    define service{
            use                     generic-service
            host_name               dns
            service_description     Total Processes
            check_command           check_nrpe_1arg!check_total_procs
    }
  3. Mulakan semula servis nagios
    /etc/init.d/nagios3 restart

    Pada server DNS (squeeze):

  1. Pasang pakej-pakej yang diperlukan
    apt-get install nagios-nrpe-server nagios-plugins
  2. Edit /etc/nagios/nrpe.cfg seperti dibawah dengan mengambil kira output “df -h”, IP server nagios & IP server DNS
    #server_address=127.0.0.1
    server_address=192.168.1.102
    
    #allowed_hosts=127.0.0.1
    allowed_hosts=192.168.1.110
    
    #command[check_hda1]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/hda1
    command[check_root]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/mapper/debian-root

    $ sudo apt-get install ubuntu-zfs

  2. Kenal pasti nama device. Dalam situasi ini, yang belum pernah dibuat partition

    $ sudo fdisk -l | grep valid
    Disk /dev/xvdc doesn't contain a valid partition table
    Disk /dev/xvde doesn't contain a valid partition table
    Disk /dev/xvdb doesn't contain a valid partition table
    Disk /dev/mapper/ubuntu--vg-root doesn't contain a valid partition table
    Disk /dev/mapper/ubuntu--vg-swap_1 doesn't contain a valid partition table

    $ sudo zpool create zfsPool1 raidz /dev/xvdb /dev/xvdc /dev/xvde -f
    $ sudo zpool status zfsPool1

      pool: zfsPool1
     state: ONLINE
      scan: none requested
    config:
    
            NAME        STATE     READ WRITE CKSUM
            zfsPool1    ONLINE       0     0     0
              raidz1-0  ONLINE       0     0     0
                xvdb    ONLINE       0     0     0
                xvdc    ONLINE       0     0     0
                xvde    ONLINE       0     0     0
    
    errors: No known data errors

    $ sudo zfs create zfsPool1/zimbraStore
    $ sudo zfs list

    NAME                        USED  AVAIL  REFER  MOUNTPOINT
    zfsPool1                    196K  9.75G  40.0K  /zfsPool1
    zfsPool1/zimbraStore       38.6K  9.75G  38.6K  /zfsPool1/zimbraStore

    $ host -t mx mylab.lab
    mylab.lab mail is handled by 10 mail.mylab.lab.

    $ hostname -f
    mail.mylab.lab

  3. Pastikan installer & installer yang digunakan adalah sesuai

    $ md5sum -c zcs-8.0.0_GA_5434.UBUNTU12_64.20120907144631.tgz.md5
    zcs-8.0.0_GA_5434.UBUNTU12_64.20120907144631.tgz: OK

    $ uname -p
    x86_64

    $ lsb_release -r
    Release: 12.04

  4. Ekstrak & install

    $ tar -xvf zcs-8.0.0_GA_5434.UBUNTU12_64.20120907144631.tgz
    $ cd zcs-8.0.0_GA_5434.UBUNTU12_64.20120907144631/
    $ sudo apt-get install libgmp3c2 libperl5.14 sysstat sqlite3
    $ sudo ./install.sh

  5. Pindah volum primaryMessage ke /zfsPool1/zimbraStore/

    $ chown zimbra:zimbra /zfsPool1/zimbraStore/

    $ zmvolume -a -n zfsStore -p /zfsPool1/zimbraStore/ -t primaryMessage
    Volume 3 is created

    $ zmvolume -sc -id 3
    Volume 3 is now the current primaryMessage volume.
