Compute node issue in OpenStack – Stockholm
2015-08-28-13:01 A reboot of a compute host ocurred. All VMs were up after the reboot. We have spent the rest of the time trying to identify why. We have found a rare kernel bug in the OS of the compute host. It seems it would be very difficult to trigger this bug therefore it has not happened over the last 6 months before. However with this knowledge we will do kernel upgrades to secure that it can not happen again.
2015-08-28 09:56 One compute node in Stockholm rebooted and took down those VMs hosted by it. It is up again and VMs are being restarted. We are looking into the reason.
