cluster1-01 cluster1-02 false Connected to cluster-02, Partial
giveback, Takeover is not possible:
The version of software running on
each node of the SFO pair is
incompatible, NVRAM log not synchronized
cluster1-02 cluster1-01 - Waiting for cluster applications to
come online on the local node
Offline applications: mgmt, vldb,
vifmgr, bcomd, crs.
如果端口未恢复正常、并且启用了连接、流明度和可用性监控(vl和平 等)
- 其中一个节点将发生"仲裁不足"崩溃。
PANIC : Received PANIC packet from partner, receiving message is (Coredump and takeover initiated because Connectivity, Liveliness and Availability Monitor (CLAM) has determined this node is out of quorum.
- 发生故障的节点将被接管、正常运行的节点将提供所有数据。
如果端口未恢复正常、并且未启用连接、流明度和可用性监控(vl和平 等)
- 不会发生存储接管、并且两个节点都将丢失仲裁。 两个节点均不提供数据。
