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

OverviewDocs:http://docs.ceph.com/docsCeph is a distributed file system that adds replication and fault tolerance while maintaining POSIX compatibility. The most characteristic of Ceph is the distributed meta-data server, which distributes the file location by crush (controlled Replication under scalable Hashing) this quasi-algorithm. The core of Ceph is the Rados (reliableautonomic distributed Object Store

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

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

In the previous blog post, we completed the Sonarqube deployment through Kubernetes's devlopment and service. Seems to be available, but there is still a big problem. We know that databases like MySQL need to keep data and not lose data. And the container is exactly the moment you exit, all data is lost. Once our Mysql-sonar container is restarted, any subsequent settings we make to Sonarqube will be lost. So we have to find a way to keep the MySQL data in the Mysql-sonar container. Kubernetes o
