[lustre-discuss] RHEL 9.8 and 10.2 support

Could you please clarify what version of Lustre you are using today for both servers and clients? Also, are you using ldiskfs or ZFS as the backend filesystem?

Hi Peter,
The new kernel presented with EL 10.2 presents changes preventing DKMS from recompiling Lustre modules.
There is even a Jira ticket following the issue since the beta, highlighting the security fixes in the new kernels.
https://jira.whamcloud.com/browse/LU-20070

Could you please elaborate as to what you feel is missing today? Lustre clients are patchless, so I would expect that if a security update is issued for a given supported release of RHEL that users would just apply the kernel update and weak updates would take care of the rest with no need to get any updates to Lustre...

Hi,
With the latest critical kernel vulnerabilities, updates are no longer optional.
This puts Lustre on the critical path for cluster security.
Is there a plan to address this necessity by releasing Lustre client versions outside of the half a year cycle to support the new kernels?
