[gpfsug-discuss] RHEL 7.5 and kernel 3.10.0-862

We have 2 power 9 nodes,

The rest of our cluster is running centos 7.4 and spectrum scale 4.2.3-8<tel:4.2.3-8> (x86 based)

The power 9 nodes are running spectrum scale 5.0.0-0<tel:5.0.0-0> currently as we couldn't get the gplbin for 4.2.3<tel:4.2.3> to compile, where as spectrum scale 5 worked on power 9 our of the box. They are running rhel7.5 but on an old kernel I guess.

I'm not sure that 4.2.3<tel:4.2.3> works on power 9 we've asked the IBM power 9 out reach team but heard nothing back.

If we can get 4.2.3<tel:4.2.3> running on the power 9 nodes it would put us in a more consistent setup.

Of course our current plan b is to upgrade everything to 5.0.1<tel:5.0.1>, but we can't do that as our storage appliance doesn't (officially) support spectrum scale 5 yet.

These are my experiences of what works and nothing whatsoever to do with what's supported, except I want to keep us as close to a supported setup as possible given what we've found to actually work. (now that's an interesting spin on a disclaimer)

Thanks Felipe,

Is it safe to assume that there is intent* for RHEL 7.5 support for Power 9 when the x86 7.5 release is also made?

Simon,

The support statement for Power9 / RHEL 7.4 has not yet been included in the FAQ, but I understand that a FAQ update is under way:

4.2.3.8 for the 4.2.3 release

5.0.0.0 for the 5.0.0 release

Kernel level tested with: 4.11.0-44.6.1.el7a

So … I have another question on support.

We’ve just ordered some Power 9 nodes, now my understanding is that with 7.4, they require the -ALT kernel (https://www.ibm.com/support/knowledgecenter/en/linuxonibm/liaam/liaamdistros.htm) which is 4.x based. I don’t see any reference in the Spectrum Scale FAQ to the ALT kernels.

So what Scale code is supported for us to run on the Power9s?

Thanks

Simon

All,

Folks that have been updated to the 3.10.0-862 kernel (the kernel which ships with RHEL 7.5) as a result of applying kernel security patches may open a PMR to request an efix for Scale versions 4.2 or 5.0 . The efixes will then be provided once the internal tests on RHEL 7.5 have been completed, likely a few days before the 4.2.3.9 and 5.0.1.1 PTFs GA (currently targeted around mid June).

Regards,

Felipe
