, they are managed separately to support extensibility. In fact, metadata is further split on a single metadata server cluster, and the metadata server is able to replicate and allocate namespaces adaptively to avoid hotspots. As shown in Figure 4, the metadata server manages the namespace portion, which can overlap (for redundancy and performance). The metadata server-to-namespace mapping is performed using dynamic subtree logical partitioning in

1.1 Introduction to installation Environment
It is recommended to install a Ceph-deploy management node and a three-node Ceph storage cluster to learn ceph, as shown in the figure.
I installed the Ceph-deploy on the Node1.
First three machines were prepared, the names of which wer

component of the assignment is the cluster map. The cluster map is a valid representation of the device and shows the storage cluster. With Pgid and cluster mappings, you can locate any object.Ceph meta-Data serverThe work of the metadata server (CMDS) is to manage the namespace of the file system.

Ceph Meta Data server
The work of the metadata server (CMDS) is to manage the namespace of the file system. Although both metadata and data are stored in an object storage cluster, they are managed separately to support scalability. In fact, metadata is further split on a metadata server cluster, and metadata servers can adaptively replicate and allocate namespaces to avoid hotspots. As shown in Fi

Deployment Installation
Regarding the installation ceph the whole process encounters the question, as well as the reliable solution, the personal test is effective, does not represent the general colleague's viewpoint.I am using the server, so I did not engage in any user issues. The machine is centOS7.3. The Ceph version I installed is jewel and currently uses only 3 nodes.Node IP naming role10.0.1.92 e10
Ceph provides three storage methods: Object Storage, block storage, and file system. The following figure shows the architecture of the Ceph storage cluster:We are mainly concerned about block storage. In the second half of the year, we will gradually transition the virtual machine backend storage from SAN to Ceph. although it is still version 0.94,
Ceph is a fully open source distributed storage solution, a network block device, and a file system with high stability, high performance, and high scalability to handle data volumes from terabyte to exabyte levels.By using innovative scheduling algorithms (CRUSH), active storage nodes, and Peer-to-peer gossip protocols, Ceph avoids the problems of scalability and reliability in traditional centralized cont
create a corresponding RBD block for kubernetes storage. Before you create a block device, you need to create a storage pool, and Ceph provides a default storage pool called RBD. We then create a kube store dedicated to storing the block devices used by kubernetes, and subsequent operations are performed on Client-node:Ceph OSD Pool Create Kube #后面两个100分别为pg-num and Pgp-numCreate an image file in the Kube storage pool called Mysql-sonar, which is 5GB
Ceph Client:Most ceph users do not store objects directly into the Ceph storage cluster, and they typically choose one or more of the Ceph block devices, the Ceph file system, and the Ceph object storage;Block device:To practice t
Ceph monitoring Ceph-dash Installation
There are a lot of Ceph monitors, such as calamari or inkscope. When I started to try to install these, they all failed, and then Ceph-dash came into my eyes, according to the official description of Ceph-dash, I personally think it is

Extended development of ceph management platform Calamari. The extended development of the ceph management platform Calamari has not written logs for nearly half a year. maybe you are getting lazy. However, sometimes writing something can help you accumulate it, and you can record the extended development of the ceph management platform Calamari.
