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,

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

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

The advantage of having a wiki on your own computer is that there is no storage space, and the downside is that the whole process is a bit more cumbersome and must have good upload bandwidth.
