Did you used patched or unpatched kernels? For clients I don't think it will matter much, since users often have to build their own client RPMs (possibly via DKMS), or they use weak updates to avoid rebuilding the RPMs at all for client updates. The Lustre client code itself works with a wide range of kernel versions (3.10-6.0 currently), and I suspect that relatively few production systems want to be on the bleeding edge of Linux kernels either, so the lack of 6.1-6.3 kernel support is likely not affecting anyone, and even then patches are already in flight for them. Definitely servers will be more tricky, since the baseline will always be moving, and more quickly than EL kernels.

Re: [lustre-discuss] CentOS Stream 8/9 support?
This has the makings of being significant enough of an impact that I don't think it is a done deal. I'm sure someone in DC is calling someone at IBM. Even if USG does nothing, this is the kind of thing that EU regulators have stomped on in the past. I suspect this isn't open and shut...yet.

Re: [lustre-discuss] CentOS Stream 8/9 support?
We have one, small Stream 8 cluster, which is currently running a Lustre client to which I cherry-picked a kernel compatibility patch. I could imagine the effort being considerably more for the server component. I also wonder, even if Whamcloud were to provide releases for Stream kernels, how many sites would be happy with Stream's five-year lifetimes. ___ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
