There is a Xenserver node in the data center. The RAID 5 made of six disks has an alarm today. It is estimated that the disk data is inconsistent. At that time, I forgot to prepare a hot spare disk. So before restarting, back up the node and restart it to verify the disk.First, check which nodes are available.[Root @ xenserver-DS-TestServer04 mnt] # xe vm-listUuid (RO): 0555a7e5-eba4-aaae-2caf-bbb4b53724aaN

Instead of developing a dedicated network stack pattern on the web itself, XenServer uses existing network stack patterns for integration. There are two main types of XenServer network stacks: Bridge and Openvswitch mode. Bridge is a Linux-system technology, and Openvswitch is an open-source Virtual Switch software. In this article I would like to talk about bridge stack mode.Bridge Chinese is called the Br

For Java users, you can use the modified Jedis ------- Jodis to implement HA on the proxy layer. It monitors the registration information on zk to obtain the list of currently available proxies in real time, which can ensure high availability or achieve Load Balancing by requesting all proxies in turn.

Eject any loaded DVD media, like Xs-tools.iso, so the virtual DVD drive is empty.
Snapshot VM before starting so you can roll back in case of problems.
Added Registry Key so the MSIServer (handles MSI Install/uninstall) can run in Safe Mode using command:REG ADD "Hklm\system\currentcontrolset\control\safeboot\minimal\msiserver"/ve/t reg_sz/f/d "Service"
Run msconfig and set computer to boot on Safe Mode with the Minimal option.
