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

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. Explore Ceph's architecture and lea

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,

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

In contrast, in a 10 Gbps network, the replication time is 20 minutes to 1 hour.

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
