[ovirt-users] Re: How restore nodes ovirt UP from NonResponsive and VMs executing

Hello Carlos, Based on the sequence of events you provided, it appears to be related to communication and storage connectivity problems. To troubleshoot this issue, here are a few steps you can take: *Verify network connectivity: Ensure that the network configuration on the ovirt2 node is correct and that it can communicate with other nodes and the storage domain. Check for any network issues or misconfigurations that could be causing the communication problems. *Check storage connectivity: Verify that the ovirt2 node can access the Storage Domain(s) attached to the Data Center. Ensure that the storage configuration is correct and that there are no connectivity issues between the node and the storage devices. *Review power management settings: As mentioned in the logs, power management for the ovirt2 host is disabled. Consider enabling power management and configuring it properly to allow for automatic fencing of non-responsive hosts. *Investigate communication issues: The timeout errors could indicate communication problems between the ovirt2 node and other components. Check for any firewall rules, network restrictions, or DNS issues that could be causing communication disruptions. *Monitor resource usage: Keep an eye on the resource usage of the ovirt2 node, such as CPU, memory, and storage. High resource utilization or potential bottlenecks can impact the node's performance and stability. *Check system logs: Review the system logs on the ovirt2 node, including VDSM logs and relevant log files, for any error messages or warnings that might shed light on the issue. I hope this helps in resolving the issue.
