A compute node might fail due to a kernel crash, power outage, or might become unreachable over the network. When the failed node becomes available again, it is fenced from scheduling new VMs on it and can be returned to operation manually.
- The compute cluster can survive the failure of only one node.
To return a fenced node back to operation
Use the following command:
vinfra service compute node unfence <node>
- Node ID or hostname
For example, to return the node
node005.vstoragedomain to operation, run:
# vinfra service compute node unfence node005.vstoragedomain
