Ocfs2 test suite

Installation
============

1. Before installation, the following rpms should be installed:

* For OL6 or OL7:
openmpi libgomp openmpi-devel mpi-selector gcc autoconf libaio-devel e2fsprogs-devel nc reflink
and ocfs2-tools(>1.6) ocfs2-tools-devel(>1.6)

* For OL5:
openmpi libgomp openmpi-devel openmpi-libs mpi-selector gcc autoconf libaio-devel e2fsprogs-devel
and ocfs2-2.6.18-348 ocfs2-tools(>1.6) ocfs2-tools-devel(>1.6)

* For SLES/opensuse:
$sudo zypper in openmpi openmpi-devel gcc autoconf libaio-devel e2fsprogs-devel ocfs2-kmp-default
ocfs2-tools ocfs2-tools-devel ocfs2-tools-devel-static

Note:
For SLE12 later, dev packages(eg. ocfs2-tools-devel) now go into SDK repo. Please add it first, like:
$sudo zypper ar sdk-repo-url sdk-repo-name

2. Add user "ocfs2test" for all nodes

3. The following environment parameters should be set in /home/ocfs2test/.bash_profile for all nodes:

* For OL6 or OL7:
PATH=$PATH:$HOME/bin:/usr/sbin/:/usr/lib64/openmpi/bin:$HOME/bin/ocfs2/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/openmpi/lib
export PATH
export LD_LIBRARY_PATH

* For OL5:
PATH=$PATH:$HOME/bin:/usr/lib64/openmpi/1.4-gcc/bin:$HOME/bin/ocfs2/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/openmpi/1.4-gcc/lib
export PATH
export LD_LIBRARY_PATH

* For SLES/opensuse:
PATH=$PATH:$HOME/bin:/usr/lib64/mpi/gcc/openmpi/bin:$HOME/bin/ocfs2/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/mpi/gcc/openmpi/lib64
export PATH
export LD_LIBRARY_PATH

Note:
Import above env variables by:
$. ~/.bash_profile

4. Install OCFS2 testing suite for all nodes through steps as follows:

*  su - ocfs2test
*  git clone https://github.com/markfasheh/ocfs2-test   #or download from github website
*  cd ocfs2-test
*  make clean
*  ./autogen.sh prefix=/
*  make
*  make install DESTDIR=/home/ocfs2test/bin/ocfs2

Setup test environment
======================

1. Get access to other nodes

* add the all hosts in cluster.conf info into /etc/hosts for EACH node.
* as "root" user and "ocfs2test" user, generate ssh id on the first node, and ssh-copy-id to other nodes

2. Add "ocfs2test" user into sudo list

* add this line into /etc/sudoers
  ocfs2test ALL=(ALL) NOPASSWD:ALL
* comment 'Defaults    requiretty' in /etc/sudoers      #no need for sles/opensuse now

3. chmod 777 /dev/sdax by root on EACH node

4. Stop iptables service for all nodes

Run the test
============

1. single node test

* login as "ocfs2test"
* cd ~/bin/ocfs2/bin;
* single_run-WIP.sh -m <mount point> -l <log_location> [-t testcase] -d <device>

e.g. ./single_run-WIP.sh -k ~/linux-kernel.tar.gz -m /mnt/ocfs2 -l ~/ocfs2log -d/dev/sdax
e.g. ./single_run-WIP.sh -k ~/linux-kernel.tar.gz -m /mnt/ocfs2 -l ~/ocfs2log -t directaio -d/dev/sdax

2. multiple nodes test

* login as "ocfs2test"
* cd ~/bin/ocfs2/bin;
* multiple_run.sh -k /kernel/linux-2.6.tgz -n node1.us.oracle.com,node2.us.oracle.com -d <device> [-t testcase] <mount point>

e.g. ./multiple_run.sh -i eth0 -k ~/linux-kernel.tar.gz -n ocfs2-test8.cn.oracle.com,ocfs2-test9.cn.oracle.com -d /dev/sdax /mnt/ocfs2
e.g. ./multiple_run.sh -i eth0 -k ~/linux-kernel.tar.gz -n ocfs2-test8.cn.oracle.com,ocfs2-test9.cn.oracle.com -d /dev/sdax -t multi_mmap /mnt/ocfs2

3. discontig single node test

* login as "ocfs2test"
* cd ~/bin/ocfs2/bin;
* discontig_runner.sh <-d device> [-o logdir] [-a access_method] <mount point>

e.g../discontig_runner.sh -d /dev/sdax -o ~/ocfs2log/ /mnt/ocfs2

4. discontig multiple nodes test

* login as "ocfs2test"
* cd ~/bin/ocfs2/bin;
* discontig_runner.sh <-d device> [-o logdir] [-m multi_hosts] [-a access_method] <mount point>

e.g. ./discontig_runner.sh -d /dev/sdax -o ~/ocfs2log/ -m ocfs2-test8.cn.oracle.com,ocfs2-test9.cn.oracle.com /mnt/ocfs2
