  aptitude install iscsitarget
  ed -s /etc/default/iscsitarget <<< $',s/ISCSITARGET_ENABLE=false/ISCSITARGET_ENABLE=true/g\nw'


=====Install iscsitarget and open-iscsi on Debian Squeeze=====

This shouldn't be to difficult in Debian:
  apt-get update apt-get install iscsitarget iscsitarget-source open-iscsi module-assistant

After install iscsitarget you should also build its kernel module (this step may skipped if you are using Debian Squeeze, by installing, e.g. iscsitarget-modules-2.6-amd64) for non-stable Debian kernel:
  module-assistant a-i iscsitarget

After that, restart iscsitarget with following command:
  /etc/init.d/iscsitarget restart 
======= Client =======
  iscsiadm -m discovery -t st -p 10.39.99.150
  iscsiadm -m node -T iqn.2009-01.avi.wd-store1:storage.mirror1.sys1 -p 10.39.99.150 --login
  iscsiadm -m session
  fdisk /dev/sda
  mkfs.ext3 /dev/sda1
  mount /dev/sda1 /mnt

Automaticke pripojeni po startu: **node.startup = automatic** do 
''/etc/iscsi/nodes/iqn.2009-01.avi.wd-store1\:storage.mirror1.sys1/10.39.99.150\,3260''


  ietadm --op new --tid=32 --params Name='iqn.2009-05.cz.panelnet:storage.tukan.vlcek'
  ietadm --op new --tid=32 --lun=0 --params Path=/dev/vg_cloud/lv_vlcek
  
Aby se automaticky pripojil i filesystem je potreba udelat tyhle zasadni veci:

  * ''pass'' v ''/etc/fstab'' musi byt ''0''
  * v ''options'' v ''fstab'' musi byt ''_netdev''
  * je pry jako nejak lepsi, kdyz je ve ''fstab'' zarizeni zapsano jako ''UUID=bordel'' nez ''/dev/disk/by-path/...'' (muj dojem je, ze by to mohlo byt jedno, ale vi buh jak ty initskripty interreaguji s ''udev''em)

===== Pro 10Gbit sitovku=====
Before installing iSCSI software, we recommend the use of sysctl to tune Myri-10G TCP/IP for iSCSI on both the Initiator and the Target. These settings recommended by open-iscsi.org work well:

    net.ipv4.tcp_timestamps = 0
    net.ipv4.tcp_sack = 0
    net.ipv4.tcp_rmem = 10000000 10000000 10000000
    net.ipv4.tcp_wmem = 10000000 10000000 10000000
    net.ipv4.tcp_mem = 10000000 10000000 10000000
    net.ipv4.tcp_tw_recycle = 1
    net.ipv4.tcp_tw_reuse = 1
    net.core.rmem_max = 524287
    net.core.wmem_max = 524287
    net.core.rmem_default = 524287
    net.core.wmem_default = 524287
    net.core.optmem_max = 524287
    net.core.netdev_max_backlog = 300000

Takova drobna poznamka je, ze tohle je pro myrinet, jehoz 10G varianta sice je vicemene totez jako 10G ethernet, ale ne uplne (ve smyslu, ze takovyhle ladeni na ethernetu stejne nema cenu).
