Notes on Linux Kernel Updates

Details

We found that updating only the kernel of the installed Linux operating system causes the OS to hang or terminate unexpectedly during the backup process.

Causes

This problem happens because when only the kernel is updated, the settings for the snapshot driver are configured before the DKMS process finishes. 

Workaround

Please update the entire package instead of just the kernel. If you prefer not to update the rest of the package, please conduct thorough testing to ensure there are no issues.

Please update the following packages when the product is installed on RHEL8/9 or clone OS.
- kernel
- kernel-core
- kernel-modules
- kernel-headers
- kernel-devel

Please update the following packages to the same version when the product is installed on RHEL7 or clone OS.
*As we have confirmed the issue that even when the following is updated, OS hangs up, please conduct the tests in advance.
- kernel
- kernel-headers
- kernel-devel

Pleae update the following packages to the same version when the product is installed on Ubuntu Debian.
- linux-image
- linux-headers

Pleae update the following packages to the same version when the product is installed on openSUSE SLES.
- kernel
- kernel-devel
