All compute nodes state appear as down
I installed OpenStack Juno and spawn some instances successfully. After a failed attempt to delete a volume, I noticed one compute node state changed to down. Shortly after that all the other compute nodes states and change to down. I have reboot all controllers, compute and storage node and state of the compute nodes still appear as down.
I am running Ceph OSD for storage.
Any what could be the cause and how to resolve it?
Tabi
can you post the nova logs from compute nodes and controller node?
Hi, Nova-api.log or nova-all.log?
Here is nova-all log excerpt from the compute node/..
182>Aug 18 22:30:04 node-10 nova-compute Skipping periodic task _periodic_update_dns because its interval is negative <182>Aug 18 22:30:04 node-10 nova-compute Loading compute driver 'libvirt.LibvirtDriver' <182>Aug 18 22:30:04 node-10 nova-comp
Checked Nova log on Controller node and nothing serious/...

yeah, nothing weird on logs..... is the Compute Node machine memory still OK?
