问题描述

在其中一个MetroCluster站点发生灾难后、MAUSO会启动、但会失败

Mon Sep 25 11:52:58 +0200 [ClusterA-01: DR_heartbeat_thread: mcc.auso.trigFailed:EMERGENCY]: A trigger for Automatic Unplanned Switchover failed to issue the operation. Reason: Switchover job could not be started. Mon Sep 25 11:52:58 +0200 [ClusterA-01: DR_heartbeat_thread: callhome.mcc.auso.trig.fail:EMERGENCY]: Call home for METROCLUSTER AUSO TRIGGER FAILED

运行正常的站点上的一个节点丢失其调解器iSCSI会话

Sep 25 11:52:38 +0200 [ClusterA-02: kernel: iscsi.session.stateChanged:notice]: iSCSI session state is changed to Reconnecting (destroy sim) for the target iqn.2012-05.local:mailbox.target.<uuid>:1 (type: mailbox, address: <IP>). Reason: session timed out 2 times waiting for iscsid(8).

然后、此节点会同时自行停止

Mon Sep 25 11:52:38 +0200 [ClusterA-02: fmmbx_instanceWorker: kern.shutdown.initiator:debug]: SK reboot was initiated by "maytag.ko::mia_mccip_local_write_partial_fail+568".
