读操作是使用本地存储执行的(除非本地磁盘发生故障,那时通过辅助节点访问辅助存储)。
Read operations are performed using local storage (unless the local disk has failed, at which point the secondary storage is accessed through the secondary node).
解决这个问题的一种方法是使用全冗余路径来访问外部SAN(存储区域网)设备—通过这种方式,可以减少因存储子系统访问问题导致的故障。
One way to counter this is by using a fully redundant path to access external SAN (storage area network) devices-in this way, you can reduce failures caused by storage subsystem access problems.
您学习了当存储路径出现故障或者存储基础设施进行维护时,如何使用多路访问显著增加xen虚拟机的正常运行时间。
You've learned how multipath access can be used to dramatically increase the uptime of Xen virtual machines in the event of storage path failure or storage infrastructure maintenance.
第3个故障组是解决磁盘仲裁问题所必需的,以便如果存储的其中一半离线之后,磁盘仲裁能立即发挥作用且文件系统也能保持总可以被访问。
The third failure group is required to solve disk quorum issues so that should either half of the storage go offline, disk quorum is satisfied, and the file system remains accessible.
