We integrated the Lustre 2.15 with ldiskfs and OpenZFS 2.1.5 under AL8.6 and AL9 with more or less the steps in integrating it for the two OSD under the Centos8.
The integration works went smoothly and they are working as expected for now.
The stability of the Lustre under the two systems are still under evaluation and do let us know in case you have some suggestions, recommendations or experiences to share with us.
Our goal is to move from Centos to AL, for the current production Lustre FS.
