ceph object storage

: Ceph Monitor maintains the cluster map status, including monitor map, OSD map, Placement Group (PG) map, and CRUSH map. ceph maintains Ceph Monitors, Ceph OSD Daemons, and historical records of PGs status changes (called an "epoch "). ? MDSs: Metadata Stored by Ceph Metada

Tags: centos cephBrief IntroductionThe deployment mode of Ceph mainly includes the following types of nodes:? Ceph OSDs: A Ceph OSD process is mainly used to store data, process data replication, recovery, and fill, adjust the resource combination and provide some monitoring information to Ceph Monitors by checking the

, error detection, error recovery will bring great pressure to the client, controller, metadata directory node, and limit the scalability.We have designed and implemented Rados, a reliable, automated distributed object store that seeks to distribute device intelligence to complex thousands of-node-scale clusters involving data-consistent access, redundant storage, error detection, and recovery of logging pr

Ceph is a software that can provide storage cluster services它可以实现将主机做成存储集群，并提供分布式文件存储的功能ceph服务可以提供三种存储方式： 1.块存储 2.对象存储 2.文件系统存储Here I'll show you how to build a storage cluster using Ceph: Environment Introduction: node1 node2 node3 这三台主机作为存储集群服务器，分别都有3块10G的硬盘，并且

As Ceph is increasingly used in various storage business processes, its performance and tuning strategy has become a topic for users to pay close attention to, one of the key factors affecting performance is the OSD storage engine implementation; The Ceph base component Rados is a strong consistent,

OSDS and/or multiple logs on the same drive on one operating system.Because a small portion of the cost of resolving performance issues may exceed the cost of additional disk drives, you can speed up your cluster design planning in order to avoid overloading the OSD storage drive.Multiple Ceph OSD Daemons are running on each hard drive at the same time, but this can lead to resource contention and lower ov

The Ceph Crush algorithm (controlled Replication under Scalablehashing) is an algorithm based on data distribution and replication for random control.Basic principle:Storage devices typically support stripe to increase storage system throughput and improve performance, and the most common way to stripe is to do raid. As RAID0.The data is distributed in strips on the hard disk in the array, which is the stor

This is a creation in Article, where the information may have evolved or changed. All the places involved in storage are very prone to "pits", Kubernetes is no exception. First, the cause of the problem The problem began yesterday by upgrading the operation of a stateful service. The pod under the service is mounted with a persistent Volume provided with Ceph RBD. The pod is deployed with normal deployment

I. OverviewCephfs is a CEpH cluster-based file system that is compatible with POSIX standards.When creating a cephfs file system, you must add the MDS service to the CEpH cluster. This service processes the metadata part in the POSIX file system, and the actual data part is processed by the osds in the CEpH cluster.Cephfs supports loading by using INCORE modules
