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

Mon Jun 4 22:48:45 BST 2018

Peter, Simon,

While I believe Power9 / RHEL 7.5 will be supported with the upcoming PTFs
on 4.2.3 and 5.0.1 later in June, I'm working on getting confirmation for
that.

We have 2 power 9 nodes,

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

The power 9 nodes are running spectrum scale 5.0.0-0 currently as we
couldn't get the gplbin for 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 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 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, 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
