Hello,

I read your webpage :Portal:PowerPC:

https://en.opensuse.org/Portal:PowerPC

I see you mention if we are having problems with something and are willing to spend some time testing, to send you an email. I have an IBM 8286-41A Power8 box and am both having an issue, and am more than glad to help testing any solutions for the issue on my system, or testing problems for other systems for that matter :-)

Before I go into detail of my issue, I want to make sure I am sending this to the correct email address, etc.

I suppose this works. There are about 0 openSUSE users on powerpc since G5 support was dropped quite a while ago but whatever.

Please let me know what you need from me in order to allow me to test things for you, and to also report my issue so that hopefully it can be corrected. My issue is actually rather severe (in my opinion) and basically renders opensuse on Power useless at this point.

You can always file a bug in the bugzilla. If you fill in the architecture correctly it should get forwarded to me eventually. Thanks Michal -- To unsubscribe, e-mail: opensuse-ppc+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ppc+owner@opensuse.org

Interesting, I would expect there to be some activity with openSUSE for POWER since it is used quite a bit in the IBM midrange world.

You mentioned I could “file a bug in the bugzilla”. Can you point me to the correct page, ect, where I would file for openSUSE for POWER?

As any opensuse bug on bugzilla.opensuse.org. Thanks Michal

Thanks!

John

Hello Michal, The problem I am having with openSUSE on POWER is that when openSUSE is notified by the IBM POWER firmware that the system is running on UPS battery power, it immediately starts a shutdown. It does not wait to see if power is restored, etc. So, if we experience a very short power outages - less then one second - the openSUSE shutsdown. I want to use use openSUSE for an email server, but cannot do that if it is going to shut down everytime there is a power glitch. My understanding of the way things are supposed to work with openSUSE on IBM POWER is that when a power outage is detected, the script /etc/rc.powerfail is supposed to be run. That script will wait a certain amount of time (configurable in the script) and if power is restored to the UPS within that amount of time, the shutdown will be cancelled. However, the rc.powerfail script is not being kicked off. The script indicates that the rtas_errd daemon must be running for the script to be invoked, and the rtas_errd daemon is indeed running. I am hoping I am just missing something simple. I have been trying to figure this out for at least six months now and it is starting to drive me crazy :-) If there are any questions, do not hesitate to ask. I can also test anything which needs to be tested, etc. Thanks! John

So what is this issue you have with openSUSE on POWER?

Thanks

Michal, I already did open a bug report, but they don’t seem to think it is a bug. The bugzilla number is 1160495 in case you want to see what they had to say. John

This is probably systemd configuration issue. Please open a bug report in bugzilla.

I have contacted the manufacture of the UPS. There is no configuration on the UPS end. The UPS contains a relay card, which sends a signal to the Power8 server when running on battery power. The UPS will then send another signal to the Power8 server when the utility power has been restored at the UPS. That signal is making it to the openSUSE LPAR because I see this when the UPS goes on battery power: ================== powerweb:~ # Loss of system power detected. System is running on UPS/battery. Check RTAS error log for details Message from syslogd@powerweb at Dec 26 14:42:06 ... kernel:Loss of system power detected. System is running on UPS/battery. Check RTAS error log for details ================== When this occurs, openSUSE starts a shutdown. Instead of it running whatever script it is running to start the shutdown, I want to run the rc.powerfail script. Do you know of anyway for me to find out what script is running which causes openSUSE to shutdown when the above conditions crops up? Thanks for your help, I do appreciate it! John

As also said in the bug it's likely systemd misconfiguration.

Please configure your UPS to work with systemd.

Thanks Michal, I will review the link you have provided and check with the linuxppc-dev mailing list if I still have problems with it. Thank you for your help, and you have a great day!! John

This message appears in the kernel: https://github.com/torvalds/linux/blob/master/arch/powerpc/platforms/pseries...

The kernel shuts down immediately on receiving the MCE.

Maybe raise the issue on the linuxppc-dev mailing list. Can't really comment on this design.

Maybe there is some information in the event that would allow the kernel decide if it needs to shut down immediately and maybe the interface is broken and there is not enough information to tell how long the battery power can last and if immediate shutdown is required.

Thanks

Michal
