Hi, cat /var/log/messages.log | grep -i error >> messages-errors.txt cat /var/log/nova/nova.log | grep -i error >> nova-errors.txt cat /var/log/audit/audit.log | grep -i error >> audit-errors.txt
in your home directory you will find the .txt files take time to trace errors, maybe you will find answers. if you have a Power-edge servers (DELL), the RC (RAID - Controller) problem is common. Otherwise you may have to check Network connections between server and switch, replace the UTP cables, and ping the other servers, rabbitMQ in OSP is depending on heart-beat to sync between servers, if the Heartbeat fails it causes this.
