[gpfsug-discuss] GPL compilation failure

[Christof Schmitt]

I cannot speak for Redhat, but the RHEL release cycles are documented: https://access.redhat.com/support/policy/updates/errata#RHEL8_and_9_Life_Cycle
The rule of thumb for Scale is that a new RHEL minor release will likely be supported in the Scale release or PTF following the RHEL release. There might be exceptions dending on the timing of the release dates, possible problems found in testing, etc.

Regards,

Christof

thanks, ryan.

I would have loved to stay with RHEL 8.7, however RHEL chose to not patch the RHEL8.7 Kernel line it seems ...

Sorry, one more thing: while you can often upgrade from say 3.10.0-1160.92.1 to 3.10.0-1160.95.1, like the kind of upgrade you’d see within an RHEL point release — and you’ll often see an older version get updated to list support for those kinds of version increments — you should definitely expect to potentially need to upgrade GPFS if you’re going between RHEL point releases, like 8.7 to 8.8 — those ones that change from, say, 4.18.0-425.x to 4.18.0-477.x.

Sometimes unsupported versions will work, but often times they will not, and if you have a support contract, that difference is sort of meaningless since you wouldn’t want to run an unsupported version anyway.

Not supported on that GPFS version; probably need a 5.1.8.x — definitely supported on 5.1.8.1.

Always check here before upgrading the kernel:

Hi, just to let you know:

building the 5.1.7.1 GPL layer for Linux Kernel 4.18.0-477.21.1.el8_8.x86_64 failed for me:

[...]

If anyone managed to build that, a message would be nice, else you should expect problems.

I opened a case with IBM but it is caught in the call entry ... (SF TS013920636, in case any supporter wants to look after it).
