…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 <usai@amazon.com>
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 <usai@amazon.com>

We improved the Lustre code to avoid build failures when Lustre is not compatible with 8.7 kernel. ### References * aws/aws-parallelcluster-cookbook#2442 Signed-off-by: Enrico Usai <usai@amazon.com>

Description of changes
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:
Before the patch: this test was failing on converge phase,
After the patch: converge is passing and printing the following WARN message:
Docker:
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.
We're overriding the kernel_release variable on docker because it does not have the same format of EC2.
