mlnx_teuthology

Mellanox Teuthology and ceph latest packages with RDMA enabled

Configuration

Runner Host <--- ssh passwordless ---> cluster nodes (1..n)

Prerequisites

The runner host and all cluster nodes must be running:

• Ubuntu 14.04

• MLNX_OFED_LINUX-3.1-1.0.3

• Accelio for_next commit 9cea8291787b72a746e42964d5de42d6d48f0e0d

  root@all-host:~# git clone git://github.com/accelio/accelio.git accelio.git

  root@all-host:~# cd accelio.git

  root@all-host:~# git checkout -b rec_commit 9cea8291787b72a746e42964d5de42d6d48f0e0d

  root@all-host:~# ./autogen.sh

  root@all-host:# ./configure --prefix=/usr/local/ root@all-host:# make j8 && make install

Prepare all nodes under test (runner-host and cluster nodes)

o Create new group and user ubuntu

root@all-host:~# useradd -u 2000 -d /home/ubuntu -m -s /bin/bash ubuntu

o Give root access to the ubuntu user. Add the following line "ALL ALL=(root) NOPASSWD:ALL" to /etc/sudoers file

root@all-host:~# vim /etc/sudoers ALL ALL=(root) NOPASSWD: ALL

o Install openssh-server and setup password-less ssh login between nodes

ubuntu@all-host:~# sudo apt-get install openssh-server

• Generate ssh-key if not present.

• Do not provide any password while generating key

• On runner-host and all cluster nodes, login as ubuntu user:

  ubuntu@all-host:~# ssh-keygen

  ubuntu@all-host:~# sudo cp f ~/.ssh/id_rsa.pub /etc/ssh/ssh_host_rsa_key.pub

  ubuntu@all-host:~# sudo cp f ~/.ssh/id_rsa /etc/ssh/ssh_host_rsa_key

• On runner-host only:

  ubuntu@runner-host:~# ssh-copy-id

o Resolve the hostnames across all cluster nodes and runner-host

For example, add rdma network and rdma hostnames in /etc/hosts 12.20.1.118 vlab-018-r1 12.20.1.119 vlab-019-r1 12.20.1.120 vlab-020-r1

o Install the following dependencies on all node

ubuntu@all-host:~# sudo apt-get install python-dev python-virtualenv python-pip libevent-dev libmysqlclient-dev python-libvirt python-yaml python-prettytable

ubuntu@all-host:~# sudo apt-get install binutils libaio1 libboost-system1.54.0 libboost-thread1.54.0 libcrypto++9 libgoogle-perftools4 libjs-jquery libleveldb1 libreadline5 libsnappy1 libtcmalloc-minimal4 libunwind8 python-blinker python-flask python-itsdangerous python-jinja2 python-markupsafe python-pyinotify python-werkzeug xfsprogs libfcgi0ldbl gdebi-core python3-chardet python3-debian python3-six gdisk cryptsetup-bin cryptsetup syslinux libffi-dev libssl-dev qemu-utils libyaml-dev libev-dev

Install and configure Teuthology

o Install teuthology and ceph-qa-suite on runner-host only

• Teuthology should be installed on the runner-host

• Runner-host should have enough storage especially /tmp directory

• Clone this project to home directory $HOME in runner-host

  ubuntu@runner-host:~# cd ~

  ubuntu@runner-host:~# git clone https://github.com/vuhuong/mlnx_teuthology

  ubuntu@runner-host:~# cd mlnx_teuthology

• Clone "teuthology" project

  ubuntu@runner-host:~# cd ~/mlnx_teuthology

  ubuntu@runner-host:~# git clone https://github.com/vuhuong/teuthology

• Change the permission of "teuthology" directory to 777 and bootstrap to install

  ubuntu@runner-host:~# cd ~/mlnx_teuthology

  ubuntu@runner-host:~# sudo chmod -R 777 teuthology

  ubuntu@runner-host:~# cd teuthology

  ubuntu@runner-host:~# ./bootstrap

• Clone "ceph-qa-suite" project

  ubuntu@runner-host:~# cd ~/mlnx_teuthology

  ubuntu@runner-host:~# git clone https://github.com/vuhuong/ceph-qa-suite

o Provide disks/partitions infomation on each OSD node

• "sudo lsblk" to find all disks/partitions available

• In the root "/" directory, create a file "/scratch/devs" and add/append available disks/partitions used in test. Teuthology will use these disks/partitions as OSD(s) in the test. The content of "/scratch_devs" file should look like this:

  /dev/sdc2
  /dev/sdd1
  /dev/sdf
  

• Change the permission of "/scratch_dev" file to 777

  ubuntu@osd-host:~# sudo chmod -R 777 /scratch_devs

o Create target file on runner-host The target file(s) will have .yaml extension Ideally one .yaml file has to be created for each test suite (bvt, ceph_qa, etc...) This file will be one of the input parameters to run the test automation suite.

"~/mlnx_teuthology/target_bvt_sample_xio.yaml" is an example.

Target file(s) is test configuration file(s) which contains the information about:

• Test setup and cleanup
• Path to test suite(s)
• Path to all built packages
• Role of each node in cluster
• Target (key details to connect to cluster nodes)
• Ceph configuration and test environment setup steps
