我花了一段时间尝试configurationPuppet，以便它将设置Cinder使用GlusterFS作为后端，而不是LVMISCSI后端，但我没有任何运气。
版本：
CONFIGS：
除了Puppet Openstackconfiguration，这工作得很好，我有我的存储节点清单以下：
class { 'cinder::backends': enabled_backends => ['glusterfs'] } class { 'cinder::volume::glusterfs': glusterfs_shares => ['192.168.2.5:/cinder-volumes'], glusterfs_mount_point_base => '/var/lib/cinder/mnt' } 导致我的存储节点上的cinder.conf如下所示：
[DEFAULT] rootwrap_config = /etc/cinder/rootwrap.conf api_paste_confg = /etc/cinder/api-paste.ini iscsi_helper = tgtadm volume_name_template = volume-%s volume_group = cinder-volumes verbose = no auth_strategy = keystone state_path = /var/lib/cinder lock_path = /var/lock/cinder volumes_dir = /var/lib/cinder/volumes rabbit_host=192.168.2.1 use_syslog=False api_paste_config=/etc/cinder/api-paste.ini glance_num_retries=0 volume_driver=cinder.volume.drivers.glusterfs.GlusterfsDriver enabled_backends=glusterfs debug=no glance_api_ssl_compression=False glance_api_insecure=False rabbit_userid=openstack rabbit_use_ssl=False log_dir=/var/log/cinder glance_api_servers=192.168.1.5:9292 volume_backend_name=DEFAULT rabbit_virtual_host=/ rabbit_hosts=192.168.2.1:5672 glusterfs_shares_config=/etc/cinder/shares.conf control_exchange=openstack rabbit_ha_queues=False glance_api_version=2 amqp_durable_queues=False rabbit_password=**redacted** rabbit_port=5672 rpc_backend=cinder.openstack.common.rpc.impl_kombu
但是，尽pipeGlusterconfiguration，我仍然得到有关LVMISCSI的错误：
2015-01-02 10:22:49.488 1005 WARNING cinder.volume.manager [-] Unable to update stats, LVMISCSIDriver -2.0.0 (config name glusterfs) driver is uninitialized. (ad infinitum)
以及一个堆栈跟踪：

我不想混淆这个问题，但如果您需要其他信息，请告诉我，并提前致谢！
编辑
我改变了我的存储节点清单，以便它包含：
class { 'cinder::backends': enabled_backends => ['gluster'] } # class { '::cinder::volume::glusterfs': # glusterfs_shares => ['192.168.2.5:/cinder-volumes'], # glusterfs_mount_point_base => '/var/lib/cinder/mnt' # } cinder::backend::glusterfs { 'gluster': glusterfs_shares => ['192.168.2.5:/cinder-volumes'], glusterfs_mount_point_base => '/var/lib/cinder/mnt' }
现在Cinder / Gluster实际上工作，但并不完美。 您会注意到我删除了卷定义并直接转到后端定义。 这似乎已经做了让Gluster和Cinder很好玩的伎俩，但我仍然得到以下在cinder-scheduler.log
WARNING cinder.context [-] Arguments dropped when creating context: {'user': u'203e3f206c5445beac797c1bcaecea8e', 'tenant': u'd588bf47f01349f39fd609440ca1d97a', 'user_identity': u'203e3f206c5445beac797c1bcaecea8e d588bf47f01349f39fd609440ca1d97a - - -'} WARNING cinder.scheduler.host_manager [req-15855071-6eaa-41a2-87a9-70be47767f28 203e3f206c5445beac797c1bcaecea8e d588bf47f01349f39fd609440ca1d97a - - -] volume service is down or disabled.

(host: media@glusterfs)
为了解决其他一些问题，我确定这个问题是由上面cinder.conf中的一些剩余的configuration位引起的。 具体来说，我删除了所有的iscsi引用，并将gluster位移出到一个单独的部分，导致：
[DEFAULT] rabbit_host=192.168.2.1 use_syslog=False api_paste_config=/etc/cinder/api-paste.ini glance_num_retries=0 enabled_backends=gluster debug=True storage_availability_zone=nova glance_api_ssl_compression=False glance_api_insecure=False rabbit_userid=openstack rabbit_use_ssl=False log_dir=/var/log/cinder glance_api_servers=192.168.1.5:9292 rabbit_virtual_host=/ default_availability_zone=nova rabbit_hosts=192.168.2.1:5672 verbose=True control_exchange=openstack rabbit_ha_queues=False glance_api_version=2 amqp_durable_queues=False rabbit_password=**redacted** rabbit_port=5672 rpc_backend=cinder.openstack.common.rpc.impl_kombu [database] idle_timeout=3600 max_retries=10 retry_interval=10 min_pool_size=1 connection=mysql://cinder:**redacted**@192.168.2.1/cinder [gluster] volume_driver=cinder.volume.drivers.glusterfs.GlusterfsDriver glusterfs_shares_config=/etc/cinder/shares.conf volume_backend_name=gluster glusterfs_mount_point_base=/var/lib/cinder/mnt
您还会注意到[database]部分，这可能会也可能不会更改。 将会更新，如果我发现任何额外的细节。
