网络连接故障场景
在这种情况下,我想询问有关网络连接失败和群集行为的详细信息。我提到两个这样的情况,但其他情况也可能是可能的。
方案1。
如果集群中的一个主机完全与网络级别的其他节点完全断开,但是主机正在启动并运行将是群集行为以及在该颗粒主机上运行的VM会发生什么
方案2。
如果集群中的所有主机都在网络级别彼此断开,但是主机和CVM正在启动和运行,则每个主机上运行的VM会发生什么。
\r\n
\r\nI want to ask about the details regarding the network connectvity failure and cluster behaviour in such cases. I am mentioning two such scenarios but other scenarios may also be possible.
\r\n
\r\nScenario 1.
\r\nIf one host in the cluster gets completely disconnected from other nodes at network level but host is up and running what will be the cluster behavior and what will happen to the vms running on that particuar host
\r\n
\r\nScenario 2.
\r\nIf all hosts in the cluster get disconnected from each other at network level but hosts and cvms are up and running, what will happen to the vms running on each host.","quoteUsername":"Muhammad Usman Ayub","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

如果您谈论的是主机与网络“丢失的网络连接”断开连接,因此它将失去与所有事物的连通性,包括与其他Nutanix群集节点”,因此在这种情况下,主机将被视为下降,而正常的Nutanix自我愈合过程将启动重新同步主机盘,以恢复磁盘的弹性对配置的RF。
在这种情况下,HOS上的所有VM都将被视为“从高visor级别”,并基于您的Hyper-Visor群集HA配置,VM的VM将在簇上的其他可用节点上自动启动。
但是,如果您是在谈论在该节点和其他Nutanix群集节点之间失去网络通信,但与此同时,它仍在启动并运行“并通过网络到达”,“我认为这不是现实的情况,因为所有Nuatnix节点和CVM都是连接在同一layer2 VLAN上。
方案2。
如果主机降低了如何通过网络到达CVM,则可以在方案1中使用有关CVM向上的情况1的应用?CVM是此主机内部的VM,并与此主机共享同一layer2 VLAN。
不要忘记,如果已经丢失的RF 2 for RF2和RF3的RF丢失的Hotanix群集将被视为下降。
\r\nin this case all VM's on the hos will be considered as down \"from the Hyper-visor level and based on your Hyper-visor Cluster HA configuration the VM's will auto start-up on other available nodes on the clusters.
\r\n
\r\nbut if you are talking about loosing the network communications between this node and other Nutanix Cluster nodes but in the same time it is still up and running \"and reached over Network\" i think this is not a realistic case as all Nuatnix nodes and CVM's are connected on the same Layer2 VLAN.
\r\n
\r\n
\r\nScenario 2.
\r\nthe same can be applied in Scenario 1 about the CVM being up while the host is down, if the host is down how the CVM will be reachable over Network? the CVM is a VM inside this host and shares the same layer2 VLAN with this Host.
\r\n
\r\ndo not forget that Nutanix Cluster will be considered as down if more than the number of applicable to be lost hosts\/disks are already lost for this RF \"1 for RF2 and 2 for RF3\".","quoteUsername":"eng_asfour","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
