Goutham Pacha Ravi 25968ce86b [manila][ci] Replace legacy jobs 
- manila-tempest-minimal-dsvm-cephfs-native and
 manila-tempest-minimal-dsvm-cephfs-nfs are both
 legacy jobs that use the now deprecated
 devstack-gate.
- We no longer need the CentOS based experimental
 jobs for manila since the manila team plans to
 delete them from their tree. Newer CentOS experiments
 can happen with the native zuulv3 style jobs.
- The jobs added are inheriting manila-tempest-plugin jobs,
 but currently don't override anything - there's a plan
 to supply overrides soon to accommodate the ceph support
 matrix that the manila team wants to test via this
 repository.
- Also make minor refactors to existing base
 jobs to make reuse of certain things easier
A future commit will remove the pre-test-hook and
post-test-hook scripts; they're presently there to allow
testing legacy jobs against older releases of
openstack/manila.

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
