2.1.1 change the eht0 ip to 172.28.11.1

Revision as of 14:41, 9 July 2015

Preparation

Nodes

IML:

  1. CentOS 6.6
  2. Cobbler
    1. let kickstart file to only install system on first partition
  3. IML

MDS

  1. CentOS 6.6
  2. RAID:
    1. small partition for MGS
    2. large partition for MDT

OSS:

  1. CentOS 6.6
  2. RAID:
    1. 2 RAID arays: r6

Network

  1. management netowrk
    1. PXE network: 172.28.11.xx
    2. subnet for eth1 on iml:
      1. ip: 172.105.0.0
      2. IPMI network: 172.105.1.xx
  2. IB network (private)
    1. IP: 192.168.0.x
  3. ETH Network (private)
    1. IP: 192.168.1.x
  4. Switch
    1. enable ETH license
  5. Cards
    1. first port IB, second port eth
  • IML
    • IP: 172.28.0.114

Hardware

  • Network
    • all IB card should be set to port1 -> IB, port2 -> ETH
    • some port on IB switch should be ETH
  • for every pair of JBOD, connect network cable directly to each other

Installation Steps

1. install cobbler

1.1 follow the steps on wiki

1.2 check all services are running, httpd, dhcpd, xinetd, cobblerd

1.3 open the ports for cobbler and disable SELINUX

# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

2 Set up IML

2.0.1 set up virtual env on CentOS

follow this page:http://wiki.bostonlabs.co.uk/w/index.php?title=KVM:_Installation_and_operation

and disable dhcp on virt-manager on this page:http://wiki.bostonlabs.co.uk/w/index.php?title=KVM:_Tips_and_Tricks#Disable_DHCP_on_KVM_Server

2.1 install and configure IML with the latest RPMs 

   32  cd /var/lib/chroma/repo/lustre
   33  ls
   34  rm -fr *
   35  ls
   36  cp -r ~/artifacts/* .
   37  ls
   38  cd ..
   39  yum install createrepo
   40  ls
   41  create /var/lib/chroma/repo/lustre
   42  createrepo /var/lib/chroma/repo/lustre #create repo for luster servers

2.1.1 change the eht0 ip to 172.28.11.1

3 deploy all other nodes using cobbler

4 deploy IEEL on all other nodes
