How Can I Upgrade the Kernel of a Linux ECS?

Scenario

If the kernel of a Linux ECS has stability or performance issues such as system breakdown, freezing, and memory leakage, or new kernel functions are required, you can upgrade the OS kernel.

Constraints

Upgrading the OS kernel may cause system instability or compatibility issues. Before the upgrade, you should know the problems that may occur during the upgrade, back up important data, and perform the upgrade with caution.

For details about how to back up the ECS, see .

• After the OS kernel is upgraded, the Linux ECS may not be able to identify the network interfaces. This will lead to network access failure.
• After the OS kernel is upgraded, the Linux ECS may not be able to identify data disks. As a result, starting system mount points fails, and the ECS cannot start.
