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?

can you post the nova logs from compute nodes and controller node?

Hi, Nova-api.log or nova-all.log?

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