I worked on root cause analysis for a strange node reboot on client’s Oracle Database Appliance yesterday.

This blog posts explains why Oracle Database Appliances re-imaging process timing may vary from 20 to 120 minutes. There are a check in the ISO:/Extras/setupodaovm.sh script that have an issue. Until the bug is fixed a) you may face different ODA nodes’ re-imaging times b) to be on the safe side check if md devices’ re-synchronization process is finished by running “cat /proc/mdstat” command before running any business critical processes on your ODA.
