自定义Ceph存储部署

4. 配置 ceph osd

在stack用户目录下建立templates目录

mkdir ~/templates

复制ceph 配置文件到templates目录中

cp /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml ~/templates/

在storage-environment.yaml中添加一段ExtraConfig 的section，格式大致如下：

parameter_defaults: #已存在的section
ExtraConfig: #这是我们要添加的section
ceph::profile::params::osds:

分别存储journal 和 osd

ceph::profile::params::osds:
'/dev/sdc':
journal: '/dev/sdb'
'/dev/sdd':
journal: '/dev/sdb'

将journal 和osd 数据放在一个硬盘内

ceph::profile::params::osds:
'/dev/sdb': {}
'/dev/sdc': {}
'/dev/sdd': {}
