Walter A. Boring IV ff1b423178 Add ceph-iscsi support 
This patch adds support for installing, configuring all required
ceph-iscsi related packages and daemons. ceph-iscsi requires kernel
version 4.16 or greater.
To enable set
ENABLE_CEPH_ISCSI=True
Adds new config options
CEPH_ISCSI_TARGET_IQN - the rbd-target-gw iqn to use to export volumes
CEPH_ISCSI_API_HOST - the rbd-target-api ip to use to listen on
CEPH_ISCSI_API_PORT - the rbd-target-api port
CEPH_ISCSI_API_USER - the rbd-target-api user for auth against the api
CEPH_ISCSI_API_PASSWORD - the rbd-target-api password for auth against the api
The following packages are required and their deps
tcmu-runner - this requires kernel version 4.16 and > to work. Ubuntu
doesn't have a prebuilt package for this, so we pull it down and compile it.
rtslib-fb - has a pypi package
configshell-fb - has a pypi package
targetcli-fb - doesn't have a pypi package.
ceph-iscsi - doesn't have a pypi package.
The reference documentaion to setup ceph-iscsi targets and daemons:
http://docs.ceph.com/docs/master/rbd/iscsi-target-cli-manual-install

Devstack Ceph Plugin

Overview

Devstack plugin to configure Ceph as the storage backend for openstack services

As part of stack.sh:

  • Installs Ceph (client and server) packages
  • Creates a Ceph cluster for use with openstack services
  • Configures Ceph as the storage backend for Cinder, Cinder Backup, Nova, Manila (not by default), and Glance services
  • (Optionally) Sets up & configures Rados gateway (aka rgw or radosgw) as a Swift endpoint with Keystone integration
    • Set ENABLE_CEPH_RGW=True in your localrc
  • Supports Ceph cluster running local or remote to openstack services

As part of unstack.sh | clean.sh:

  • Tears down the Ceph cluster and its related services

This plugin also gets used to configure Ceph as the storage backend for the upstream Ceph CI job named gate-tempest-dsvm-full-devstack-plugin-ceph

Usage

  • To get started quickly, just enable the plugin in your local.conf:

    enable_plugin devstack-plugin-ceph https://opendev.org/openstack/devstack-plugin-ceph

    Run stack.sh in your devstack tree and boom! You're good to go.

  • Ceph is setup as the default storage backend for Cinder, Cinder Backup, Glance and Nova services. You have the ability to control each of the enabled services with the following configuration in your local.conf:

    ENABLE_CEPH_CINDER=True # ceph backend for cinder
ENABLE_CEPH_GLANCE=True # store images in ceph
ENABLE_CEPH_C_BAK=True # backup volumes to ceph
ENABLE_CEPH_NOVA=True # allow nova to use ceph resources

    Change any of the above lines to False to disable that feature specifically.

  • Ceph can be enabled as the storage backend for Manila with the following setting in your local.conf:

    ENABLE_CEPH_MANILA=True

    CephFS Native driver that supports native Ceph protocol is used by default. To use CephFS NFS-Ganesha driver that supports NFS protocol add the setting:

    MANILA_CEPH_DRIVER=cephfsnfs

    Make sure that the manila plugin is enabled before devstack-plugin-ceph in the local.conf file.

  • Then run stack.sh and wait for the magic to happen :)

Known Issues / Limitations

  • Rados Gateway with Keystone for Swift - works on Ubuntu only
  • Tempest test failures when using RGW as swift endpoint
  • Tempest fails due to verify-tempest-config erroring out, when using RGW as swift endpoint
  • Manila with CephFS - for Ubuntu, support only for Trusty Tahr (14.04 LTS) and beyond

TODOs

  • Fix Rados Gateway with Keystone for Swift on Fedora
