红帽全球峰会5.3. 启用 Ceph 元数据服务器
Ceph 元数据服务器(MDS)运行 ceph-mds 守护进程。此守护进程管理与 CephFS 中存储的文件相关的元数据。CephFS 可以原生使用，或者通过 NFS 协议使用。
注意
红帽支持使用共享文件系统服务(manila)的原生 CephFS 和 CephFS NFS 后端部署 Ceph MDS。
流程
要启用 Ceph MDS，请在部署 overcloud 时使用以下环境文件：
/usr/share/openstack-tripleo-heat-templates/environments/cephadm/ceph-mds.yaml
/usr/share/openstack-tripleo-heat-templates/environments/cephadm/ceph-mds.yamlCopy to Clipboard Copied! Toggle word wrap Toggle overflow
注意
默认情况下，Ceph MDS 部署在 Controller 节点上。您可以在自己的专用节点上部署 Ceph MDS。
