First, pre-installation preparation
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

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,

Article, where the information may have evolved or changed.
In the article "using Ceph RBD to provide storage volumes for kubernetes clusters," we learned that one step in the integration process for kubernetes and Ceph is to manually create the RBD image below the Ceph OSD pool. We need to find a way to remove this manual step. The first th

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

Ceph environment setup (2)1. There are three layout hosts: node1, node2, and node3. Each host has three osdks, as shown in figure. osd1, and 8 are SSD disks, 4 is the SATA disk. Each of the three hosts has a Monitor and an MDS. We use osd1, 3, and 4 to create a pool named ssd, in the form of three copies, osd0, and 2, 4 to build a Pool named sata, in the form of Erasure code, k = 2, m = 1, that is, use two osdks to store data fragments, one osd to sto
As an architect in the storage industry, I have a special liking for file systems. These systems are used to store the user interfaces of the system. Although they tend to provide a series of similar functions, they can also provide significantly different functions. CEpH is no exception. It also provides some of the most interesting features you can find in the file system.
CEpH was initially a PhD resea

Explore Ceph file systems and ecosystemsM. Tim Jones, freelance writerIntroduction: Linux® continues to expand into scalable computing space, especially for scalable storage. Ceph recently joined the impressive file system alternatives in Linux, a distributed file system that allows for the addition of replication and fault tolerance while maintaining POSIX compatibility.

Ceph was originally a PhD research project on storage systems, implemented by Sage Weil in University of California, Santa Cruz (UCSC). But by the end of March 2010, you can find Ceph in the mainline Linux kernel (starting with version 2.6.34). Although Ceph may not be suitable for production environments, it is useful for testing purposes. This article explores
