About This Book

Implement a Ceph cluster successfully and gain deep insights into its best practicesHarness the abilities of experienced storage administrators and architects, and run your own software-defined storage systemThis comprehensive, step-by-step guide will show you how to build and manage Ceph storage in production environment

Who This Book Is For

This book is aimed at storage and cloud system engineers, system administrators, and technical architects who are interested in building software-defined storage solutions to power their cloud and virtual infrastructure. If you have basic knowledge of GNU/Linux and storage systems, with no experience of software defined storage solutions and Ceph, but eager to learn this book is for you.

What You Will Learn

Understand, install, configure, and manage the Ceph storage systemGet to grips with performance tuning and benchmarking, and gain practical tips to run Ceph in productionIntegrate Ceph with OpenStack Cinder, Glance, and nova componentsDeep dive into Ceph object storage, including s3, swift, and keystone integrationBuild a Dropbox-like file sync and share service and Ceph federated gateway setupGain hands-on experience with Calamari and VSM for cluster monitoringFamiliarize yourself with Ceph operations such as maintenance, monitoring, and troubleshootingUnderstand advanced topics including erasure coding, CRUSH map, cache pool, and system maintenance

In Detail

Ceph is a unified, distributed storage system designed for excellent performance, reliability, and scalability. This cutting-edge technology has been transforming the storage industry, and is evolving rapidly as a leader in software-defined storage space, extending full support to cloud platforms such as Openstack and Cloudstack, including virtualization platforms. It is the most popular storage backend for Openstack, public, and private clouds, so is the first choice for a storage solution. Ceph is backed by RedHat and is developed by a thriving open source community of individual developers as well as several companies across the globe.

This book takes you from a basic knowledge of Ceph to an expert understanding of the most advanced features, walking you through building up a production-grade Ceph storage cluster and helping you develop all the skills you need to plan, deploy, and effectively manage your Ceph cluster. Beginning with the basics, you'll create a Ceph cluster, followed by block, object, and file storage provisioning. Next, you'll get a step-by-step tutorial on integrating it with OpenStack and building a Dropbox-like object storage solution. We'll also take a look at federated architecture and CephFS, and you'll dive into Calamari and VSM for monitoring the Ceph environment. You'll develop expert knowledge on troubleshooting and benchmarking your Ceph storage cluster. Finally, you'll get to grips with the best practices to operate Ceph in a production environment.

Style and approach

This step-by-step guide is filled with practical tutorials, making complex scenarios easy to understand.

这本书的排版和图表设计也拖了后腿,使得理解复杂概念的难度成倍增加。很多本应清晰明了的架构图,被设计得密密麻麻,线条交错复杂,配色也极其单调,完全没有起到辅助理解的作用,反而成了视觉上的干扰源。我需要花费比阅读文字本身更多的时间去解析那些图表,试图辨认出哪些是数据流,哪些是控制流。此外,代码示例部分的处理也显得非常敷衍,很多示例代码片段没有被格式化得易于阅读,重要的配置参数和变量名称混在一起,看起来就像是一大坨文字粘贴了上去。在技术书籍中,清晰的排版和高质量的图示是至关重要的,它们是连接作者思想与读者大脑的桥梁。遗憾的是,这本书的“桥梁”似乎摇摇欲坠,很多地方需要我自行脑补和重新绘制结构图才能勉强理解作者想表达的意思。

评分

从实战价值的角度来看,这本书的更新速度似乎跟不上Ceph本身迭代的速度,这一点让我对它的长期参考价值深表怀疑。我注意到书中引用的某些命令和API在最新的Ceph版本中已经被弃用或者发生了行为上的改变。虽然技术书籍的更新总会有滞后性,但对于一个快速发展的开源项目来说,这种滞后是致命的。我不能指望用一本介绍过时技术的“食谱”来指导我部署一个面向未来的生产环境。此外,书中对Kubernetes环境下Ceph存储部署(Ceph Rook Operator)的讨论非常浅薄,基本停留在概念介绍层面,完全没有提供那种深入到YAML配置细节和Helm Chart定制的实战经验。购买一本技术书,我期待的是可以被“使用”而不是仅仅被“阅读”的知识,而这本书,读完后留给我的更多是概念上的困惑和对部署实践的无力感。

评分

这本所谓的“食谱”简直是把我带入了云存储的迷宫,而不是我期望的,一个清晰、可操作的指南。我原本是冲着“Cookbook”这个名字来的,期待着能找到像专业厨师那样,一步步教我如何烹饪出稳定、高效的Ceph集群的秘籍。然而,我打开书后,发现自己手里拿的更像是一本理论堆砌的教科书,里面充斥着大量晦涩难懂的术语和概念的描述,但真正能让我立刻上手解决实际问题的操作步骤却少得可怜。我花了大量时间去理解那些基础架构的背景知识,这本该是快速上手后才能深入钻研的内容,却被摆在了最显眼的位置。当我真的需要解决一个常见的部署问题时,我发现书中的例子过于理想化,完全没有考虑到生产环境中可能遇到的各种复杂情况,比如网络延迟、硬件故障模拟或者不同Linux发行版之间的细微差异。这本书更像是为那些已经对Ceph了如指掌的专家准备的参考手册,而不是为我这种渴望快速掌握并部署新系统的管理员设计的工具书。它更像是知识的陈列馆,而不是实用的操作手册。

评分

关于性能调优和故障排查的部分,这本书的表现更是令人失望,简直是蜻蜓点水,意到为止。我购买这本书的主要目的之一,就是希望它能提供一些“秘籍”——那些社区论坛上流传已久但未被官方文档充分解释的性能优化技巧,或者是在面对数据不一致性时的详细诊断流程。然而,书里给出的解决方案往往停留在理论层面,比如“调整某些内核参数以提高I/O性能”,但却完全没有提供一个具体的基准测试环境,或者指导读者如何科学地评估这些调整带来的实际效果。更要命的是,当涉及到复杂的故障恢复场景时,书中只是笼统地提到了几个命令,却没有深入剖析为什么这些命令有效,或者在特定错误代码出现时应该如何连锁反应地进行排查。这使得我对Ceph的信心没有丝毫增加,反而觉得它依然是一个黑箱,而这本书,并没有提供打开这个黑箱的万能钥匙。

评分

阅读体验简直是一场智力上的马拉松,毫不夸张地说,我感觉自己像是在试图破解一份古老的密码本。这本书的叙事逻辑极其跳跃,前一页还在讲OSD的内部工作原理,下一页就突然跳到了集群监控的最佳实践,两者之间几乎没有任何平滑的过渡或者逻辑上的承接。这种结构上的混乱,使得学习过程充满了挫败感。我尝试按照章节顺序阅读,但很快就迷失了方向,因为作者似乎默认读者已经对Ceph的各个组件有着深刻的理解,并习惯于这种非线性、碎片化的信息传递方式。如果我是一个初学者,这本书会立刻把我劝退;即使是经验稍丰富的人,也需要不断地在不同章节间来回翻阅,试图拼凑出一个完整的概念图景。它缺乏那种引导性的叙事节奏,没有精心设计的学习路径,读起来干巴巴的,让人提不起精神去深入研究那些本该很有趣的分布式存储技术。

评分

在读第二版。作为Hadoop PMC,我可以负责任地说,里面关于HDFS的评价基本都是错的。
