In this two-part series, daniel robbins introduces you to linux 2.4 software raid, a technology used to increase disk performance and reliability by distributing data over multiple disks 在这两篇系列文章中,danielrobbins介绍了linux2.4软件raid一种通过将数据分布于多个磁盘,从而增强磁盘性能和可靠性的技术。
In his two-part series on the linux 2.4 software raid, daniel robbins introduces the new technology that s used to increase disk performance and reliability by distributing data over multiple disks 在danielrobbins关于linux2.4软件raid的两篇文章中,他引入了一种通过将数据分布在多个磁盘上来增强磁盘性能和可靠性的新技术。
Obviously, this means that if having a highly-available system isn t a priority for you, then you shouldn t be implementing software raid, unless you plan to use it primarily as a way to boost file i o performance 显然,这意味着,如果拥有一个高可用性系统并非您的首选,就不应该实现软件raid,除非您计划将它主要用作一种提高文件i/o性能的方法。
This means that using software raid does not allow you to escape filesystem issues, such as long and potentially problematic fscks if you happen to be using a non-journalled or flaky filesystem 这意味着,使用软件raid并不能避开文件系统问题,例如,如果您恰好在使用一种非日志文件系统或者定期整理碎片的文件系统,则可能存在耗时且易出问题的文件系统检查。
Now, and only now, should you consider implementing software raid-1, 4 or 5-by doing so, you ll potentially give your server a few more percentage points of uptime by guarding it against a complete drive failure 此时,也只有在此时,读者才应该考虑实现软件raid-1、4或5这样做以后,您就可以预防服务器出现全面驱动器故障,从而潜在地将服务器的正常运行时间延长了几个百分点。
Now would be a good time to carefully read these messages, because they ll help you to understand the process that the kernel uses to autostart dev md0, giving you another valuable insight into the inner workings of linux software raid 现在仔细读一下这些信息,因为它们将有助于理解内核用于自动启动/dev/md0的过程,从而使您从另一方面对linux软件raid的内部工作原理有一个有益的理解。
