Configuring Cinder to use Ceph block devices. Ceph: What is it and why does it have such a huge following in the OpenStack world? The TL;DR; is that Ceph is a scale-out storage system based on an object store. [DEFAULT] section, enable Ceph as a backend for Cinder. Here is a look at some Ceph¶ Starting with Luminous, Ceph can export metrics with ceph-mgr prometheus module. Benefits from Ceph Storage for OpenStack Private Cloud. Examples use the standard stack user in the OpenStack environment. It can be adapted to perfectly suit your storage needs, with industry-leading levels Prepare Nodes for OpenStack Deployment and Integration with Ceph. When you use Red Hat OpenStack (RHOSP) director, the Controller nodes host the Ceph daemons, such as the manager, metadata servers (MDS), and monitors (MON) and the Shared File Systems services. One Ceph cluster will be used for k8s RBD storage and while other Ceph cluster will be for tenant facing storage backend for Cinder and Glance. Volumes: Volumes are block devices. Ceph's flexibility is one of its many strengths. Client Client The Red Hat OpenStack Platform can use Ceph block devices for Cinder, Cinder Backup, Glance, and Nova. Compute nodes can host one or more projects. Openstack Deployment. Configuring Cinder; 3. Additionally, you must make the choice to use an erasure coded pool or a replicated pool (the default) when you initially deploy. One productiv ceph pool over all OSDs: Size 3/2 So the over all amount off space is round about 26TB, the Today, OpenStack is managed by the nonprofit OpenStack Foundation. It has been around for quite a while but is fairly limited (it uses rsync to replicate data, scaling rings can be problematic and it only check using volume from list. Configuring Cinder Backup; 3. openstack volume list set status to available to a volume. All (meta)data stored in RADOS. We will see how to integrate three prominent OpenStack use Ceph is an open source distributed storage software based on object storage on a computer cluster. We will integrate the Ceph storage backend on the Charmed Kubernetes cluster we built earlier. The main use case for Ceph within Red Hat was storage for Red Hat OpenStack. Within the OpenStack framework, storage comes in two main flavours – ephemeral and persistent. yaml under the ceph_mgr_enabled_plugins key by appending prometheus to the list of enabled modules. 4. Set to ovn to use OVN-based containers. What is CephFS? Why use it? Clients access data directly via RADOS. With its ability to solve for multiple use-cases from a single cluster, its robust disaster recovery features, and its overall ease of management thanks to Juju, Charms and the Ceph Dashboard, it is easy to see why over 70% of OpenStack clouds use Ceph as their preferred backend. This can be useful when booting from volume because a new volume can be provisioned very quickly. Deployers can enable the ceph-install. What’s expected from this Demo. In eMAG we use it in combination with OpenStack but not only. For more information, and CephFS by using the openstack overcloud deploy command with custom roles and environments. Three parts of OpenStack integrate with Ceph’s block devices: Images: OpenStack One of the key advantages of integrating Ceph with OpenStack is the ability to manage block and object storage seamlessly within a cloud environment. If not defined, director uses the Red Hat OpenStack Platform version number as the default value. connecting to your own ceph cluster by pointing to its information in user_variables. Kolla has the ability to setup your Ceph pools as erasure coded pools. 1 Ceph简介. - Second, Install OpenStack cluster integrated with ceph storage. After enabling the prometheus module, metrics can be scraped on the ceph-mgr service endpoint. Also, I’d stand up ceph separately from openstack rather than using the openstack capability to stand up ceph. This guide shows how to setup multiple Ceph clusters.
