ceph machine

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. alt

The machine is centOS7.3. The Ceph version I installed is jewel and currently uses

can skip it. I have not installed this file, or I will not write this article... If the installation fails, follow these steps. Because ceph-dash is written in python, it is missing some additional ceph software package: Flask when I fail to succeed. After installing Flask, it should be okay to run ceph-dash again, if you are still not OK, then I can't help it,

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

Ceph installation and deployment in CentOS7 Environment Ceph Introduction Eph is designed to build high performance, high scalibility, and high available on low-cost storage media, providing unified storage, file-based storage, block storage, and Object Storage. I recently read the relevant documentation and found it interesting. It has already provided Block Storage for openstack, which fits the mainstream

their software. In this process, they also use a variety of different tools to build and manage their environment. I wouldn't be surprised if I saw someone using Kubernetes as a management tool.Some people like to apply the latest technology to production, otherwise they will feel the work is boring. So when they see that their favorite open source storage solutions are being containerized, they will be happy with the way they are "all containerized."Unlike traditional Yum or apt-get, container

This is a creation in 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

As we all know, the traditional end-to-end solution is based on the data

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

, so as to simplify deployment and O M while meeting the needs of different applications. In Ceph systems, "distributed" means that the system has a truly decentralized structure and has no theoretical limit for scalability. The first three articles are about the background. Starting from the fourth article, Zhang Yu introduced the Ceph structure. The core of Ceph
