Troubleshooting Tip: Event Integrity validation for random event files remain 'Not validated' as validation fails with error 'fileValidationResponse: file not found' in backend logs

Event integrity validation from ADMIN -> Settings -> Event Integrity shows 'Not validated' for random event files with 'fileValidationResponse: file not found' error in log file /opt/phoenix/log/phoenix.log as the event file actually does not exist in event storage (/data).

1. Check for logs with the keyword CORRUPTED or UNABLE_CREATE_DIR in /opt/phoenix/log/phoenix.log:

grep -E 'CORRUPTED|UNABLE_CREATE_DIR' /opt/phoenix/log/phoenix.log

2. Remove corrupted event files from /data based on the output from step 1:

rm <eventFilePath>

3. Enforce ownership:

chown -R admin.admin /data/eventdb/

chown -R admin.admin /archive/

4. Restart phDataManager on supervisor and worker nodes:

killall -9 phDataManager
