Hi,
We are adding a new node in our cluster which is running on Oracle Linux 5.6 with Unbreakable kernel.
When running the cluvfy before ading the new node, we got the following WARNING:

WARNING:
PRVF-7524 : Kernel version is not consistent across all the nodes.
Kernel version = "2.6.32-300.11.1.el5uek" found on nodes: whml21756.
Kernel version = "2.6.32-300.20.1.el5uek" found on nodes: whml21758.
Result: Kernel version check passed

My question is : Are all nodes of a cluster must be on the same version of kernel ?

Thanks.
