Troubleshooting compute nodes
• Compute nodes do not appear on overview screen (page 173)
• Import cluster action does not complete (page 174)
• Activate compute node action is unsuccessful (page 174)
• Deactivate compute node action is unsuccessful (page 176)
• Delete compute node action is unsuccessful (page 176)
• Red Hat netcf bug fix update corrects libvirt issues (page 176)
Compute nodes do not appear on overview screen
Possible cause and recommendationSymptom
No KVM compute nodes are configured for use
1. Make sure that all prerequisites have been met for each target compute
node.
The KVM compute node network configuration is incorrect
No KVM compute nodes are visible on
the Compute Nodes overview screen
1. Run ifconfig to check the network configuration on the compute node.
The DHCP server on the CloudSystem Console appliance must recognize
the compute node.
2. If the compute node is connected to the appliance (eth1 has a valid DHCP
IP address), edit the file /etc/sysconfig/networks on the compute
node with the following entries:
NETWORKING=yes
HOSTNAME=<change-name>
DHCP_HOSTNAME=<NON-FQDN>
Local yum repositories are causing issues
1. Remove any locally defined yum repositories that may be interfering with
activation.
2. When reactivating a compute node, make sure any leftover active yum
repositories are removed.
The CloudSystem Console is displaying cached data
1. Refresh the Compute Nodes screen.
TIP: Check the following logs for additional information:
• Foundation base appliance: /var/log/isc/activity
<yourhostname>.log
• KVM compute node: /var/log/secure
