Ø  I had no idea about this bmc thing Ill check it out.
Use ipmitool to query if you have a BMC. I suspect not as this requires configuration and the defaults are off.

Subject: Re: [Openstack-operators] Compute nodes reboot periodically by their own


Thanks for the ideas! They are cheap clone servers using Intel® Server Board S5520HC with 48Gb of RAM.

-The nodes simply reboot, without any interesting logs. Not all at the same time.

-There's no automatic updates or anything like it.

-I don't think overheating is the problem, because they reboot early in the morning when they have no load at all. They usually reboot around 03:00 to 05:00 AM.

Hi,

Your compute nodes reboot or are shut off?

I am currently looking at some cases where VMs seem to spontaneously shut themselves
off. At least from the nova logs’ perspective there is no difference to a normal shutdown,
VM owners however confirm that they did not touch their VMs. So far I was unable to
explain this.

This is with Havana on a RHEL6 derivative, though.

Cheers,
 Arne

Everything works just fine, but... the compute nodes reboot themselves periodically, sometimes every 2 weeks, some times once a month. I've done almost everything I can think of: memory checks, analysed the logs, moved all the VMs to one node, and I just can't find the problem.
