…Lustre The latest RHEL8.7 kernel 4.18.0-425.19.2.el8_7 introduced a kABI regression, causing Lustre to re-release the client compiled for this latest version. This change means that this same client will not modprobe for kernel 4.18.0-425.13.1.el8_7. With this patch we're skipping Lustre installation and printing a warning in the log, like we did for 4.18.0-425.3.1.el8 that has a similar issue. ### Tests EC2: ``` # RHEL-8.7.0_HVM-20230330-x86_64-56-Hourly2-GP2 in eu-west-1 # with kernel 4.18.0-425.13.1.el8_7 export KITCHEN_RHEL8_AMI=ami-0fa2f7b35eeb82b7a bash kitchen.ec2.sh environment-install test lustre-rhel8 ``` Before the patch: this test was failing on converge phase, After the patch: converge is passing and printing the following WARN message: ``` WARN: FSx for Lustre is not supported in kernel version 4.18.0-425.13.1.el8_7.x86_64 of RHEL 8.7, please update the kernel version ``` Docker: ``` bash kitchen.docker.sh environment-install test lustre-rhel8 ``` This test passes because in docker we have RHEL 8.8 with a fake value for kernel version and we're skipping modprobe command. Use 477 version in the kernel release test variable to match 8.8 kernel version available on docker. ### References * 4.18.0-425.3.1 issue: https://access.redhat.com/solutions/6985596 * 4.18.0-425.19.2 issue: openzfs/zfs#14724 Signed-off-by: Enrico Usai <[email protected]>

We're overriding the kernel_release variable on docker because it does not have the same format of EC2. Adding the "fake-value" word in the kernel version simplifies debugging on docker. Signed-off-by: Enrico Usai <[email protected]>
