CVM group is not online after adding a node to the SF Oracle RAC cluster
The possible causes for the CVM group being offline after adding a node to the cluster are as follows:
The cssd resource is configured as a critical resource in the cvm group.
Other resources configured in the cvm group as critical resources are not online.
To resolve the issue if cssd is configured as a critical resource
- Log onto one of the nodes in the existing cluster as the root user.
- Configure the cssd resource as a non-critical resource in the cvm group:
# haconf -makerw # hares -modify cssd Critical 0 # haconf -dump -makero
To resolve the issue if other resources in the group are not online
- Log onto one of the nodes in the existing cluster as the root user.
- Bring the resource online:
# hares -online resource_name -sys system_name
- Verify the status of the resource:
# hastatus -resource resource_name
- If the resource is not online, configure it as a non-critical resource only if the resource is not critical :
# haconf -makerw # hares -modify resource_name Critical 0 # haconf -dump -makero
