In the meantime, if you are ever in the position of wanting to move to kernel versions ahead of formal support being available, my recommendation would be to experiment with a limited number of clients (perhaps even just one) before rolling out across all the
clients.</div>

Hi Peter,</div>
<div class="ms-outlook-mobile-reference-message skipProofing" style="direction: ltr;">
For the EL 10.1 client I was using version 17.0 which was the only version to support EL 10. After upgrading to EL 10.2 the client lost the storage mount.</div>
<div class="ms-outlook-mobile-reference-message skipProofing" style="direction: ltr;">
I'm not updating the EL9.7 clients, not to risk losing the storage mount. They are running the 2.15 LTS Lustre.</div>
<div class="ms-outlook-mobile-reference-message skipProofing" style="direction: ltr;">
On the servers I am still using the 2.15 version on EL 8.10 as I prefer to use the LTS version, and there is no LTS server support beyond EL 8.10.</div>
<div class="ms-outlook-mobile-reference-message skipProofing" style="direction: ltr;">
This complex matrix just emphasizes how much Lustre is a restrictive factor for upgrades.</div>

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?</div>

<div style="direction: ltr;">Hi Peter,</div>
<div style="direction: ltr;">The new kernel presented with EL 10.2 presents changes preventing DKMS from recompiling Lustre modules.</div>
<div style="direction: ltr;">There is even a Jira ticket following the issue since the beta, highlighting the security fixes in the new kernels. </div>

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...</div>

<div style="direction: ltr;">Hi,</div>
<div style="direction: ltr;">With the latest critical kernel vulnerabilities, updates are no longer optional.</div>
<div style="direction: ltr;">This puts Lustre on the critical path for cluster security.</div>
<div style="direction: ltr;">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?</div>
