问题描述

RHEL 超时配置—发生分区重新分配集群事件后几秒内发生主机断开连接和中断
  • 此示例中已启用 Red Hat Linux 开发映射程序多路径，并将 iSCSI 会话超时设置为 5 秒。此配置要求在达到 5 秒超时时间后，可以使用另一条路径进行故障转移。
    • 示例 RHEL 主机故障路径：

kernel: session10: session recovery timed out after 5 secs
kernel: device-mapper: multipath: Failing path <>.
multipathd: <> remaining active paths: 0
kernel: device-mapper: multipath: Reinstating path <>.
multipathd: <> remaining active paths: 1
