Node OS

Check Item

Check whether the OS kernel version of the node is supported by CCE.

Solution

Running nodes depend on the initial standard kernel version when they are created. CCE has performed comprehensive compatibility tests based on this kernel version. A non-standard kernel version may cause unexpected compatibility issues during node upgrade and the node upgrade may fail. For details, see High-Risk Operations and Solutions.

Currently, this type of nodes should not be upgraded. You are advised to reset the node to the standard kernel version before the upgrade by following the instructions in Resetting a Node.
