适用场景

  • 适用于运行版本 16 和 18 的 Ubuntu 系统的 Nova 中的 OpenStack 多路径设置。
  • 适用场景正在使用 OpenStack Nova 从非多路径迁移到多路径。

问题描述

使用 OpenStack Nova 版本为 SolidFire 卷启用多路径的最佳实践 

问题签名:
尝试挂载配置不正确的 Element S/SolidFire 卷时,客户端 VM 挂起。
这是适用于 Ubuntu 16 和 18 的已知问题描述,在版本 20 中已修复。之所以出现问题描述,是因为 SolidFire 卷的 IQN 过长。 

当前错误:在 Ubuntu 18.04
Nova 数据库字段 connection_info 中,如果多路径挂起且 iSCSI 目标名称较长target_portal,则此字段的词典包含字段 " " (非多路径)。该词典中还有其他字段。
