Ran into some weird behavior in regards to my embedded vRO instance packaged alongside vRA 8.0.1. After upgrading from 8.0 through LCM using the ISO, I was unable to run any workflows whatsoever. Logs on the run itself were empty, and any workflow would just hit a "failed" state, even a workflow that just had a start and end step. To troubleshoot, I tried:
1. Checking the logs at /data/vco/usr/lib/vco/app-server/logs/*
2. Restarting just the vRO services through kubectl.
3. Restarting the whole stack with:
Ended up reverting back to 8.0 via the snapshot LCM created and I can run workflows again. Is there some known issue or KB around this? I might just gut it out until a later release comes passed 8.0.1 if this is a known issue. I'm assuming that the upgrade for the embedded instance is inside the ISO for vRA.
Have you checked vRO pod/containers logs? Not all the logs are available in files under /data/vco/usr/lib/vco/app-server/logs/*, some of the logged data are now dumped on standard output and can be fetched via kubectl as pod/container logs.
