适用场景

  • 根数据 数据
  • 突袭组
  • 高级磁盘分区(ADP)

问题解答

如果满足以下所有条件,则 HA 对中一个节点拥有的单个备用 SSD 可以用作“全局”备用 SSD:

  1. AutoSupport 部分COREDUMP-STATUS.xml显示“核心转储类型”=“corefs”
  2. 系统必须修复错误 1361016

对于其他配置,单个未分区的 SSD 将无法用作全局备用:自动分区、更改所有权,并用于重建降级的 raid 组。

对于未显示“核心转储类型”=“corefs”的型号,Root-Data-Data 配置可以手动分区和分配。  每次更换驱动器后都必须手动执行此操作,如果发生崩溃,将导致没有可用于分析的核心。
