回复: 重启实例后实例内数据消失的问题

没遇到过这种问题。
你的hyperviser和guest vm分别是什么系统?

大家好,
    最近遇到了如下问题,点击网页中的重启实例,发现实例中的数据消失(与重装实例的效果一样)。如果再实例中执行reboot命令,则数据不会消失。

把主存储挂在所有的计算节点,同理iSCSi的也一样‍

用FC来做主存储 是把主存储挂在所有的计算节点还是 管理节点,还是挂在在所有的机器上   都没有这方面的资料啊

HA for Management Server

The CloudStack Management Server should be deployed in a multi-node configuration such that it is not susceptible to individual server failures. The Management Server itself (as distinct from the MySQL database) is stateless and may be placed behind a load balancer.

Normal operation of Hosts is not impacted by an outage of all Management Serves. All guest VMs will continue to work.

When the Management Server is down, no new VMs can be created, and the end user and admin UI, API, dynamic load distribution, and HA will cease to work.

Management Server Load Balancing

CloudStack can use a load balancer to provide a virtual IP for multiple Management Servers. The administrator is responsible for creating the load balancer rules for the Management Servers. The application requires persistence or stickiness across multiple sessions. The following chart lists the ports that should be load balanced and whether or not persistence is required.

Source port     Destination port        Protocol        Persistence Required?
80 or 443       8080 (or 20400 with AJP)        HTTP (or AJP)   Yes
8250    8250    TCP     Yes

In addition to above settings, the administrator is responsible for setting the ‘host’ global config value from the management server IP to load balancer virtual IP address. If the ‘host’ value is not set to the VIP for Port 8250 and one of your management servers crashes, the UI is still available but the system VMs will not be able to contact the management server.

你安装实例的时候使用ISO还是模板,如果是ISO,是不是自动化安装?如果是ISO安装的,重启时实例默认是由ISO启动,会不会是自动重装了?
