Probable cause postman
db-backup CronJob in lineth-l2 dumps the L2 Postgres databases (coordinator, postman, transaction exclusion, blockscout) once a day. No successful run in 26 hours means the last good backup is older than a day.Hours since the last successful backup:
(time() - max(kube_cronjob_status_last_successful_time{namespace="lineth-l2", cronjob="db-backup"})) / 3600Failed backup jobs:
sum(kube_job_status_failed{namespace="lineth-l2", job_name=~"db-backup-.*"})If backups cannot run for 48 hours, open an incident and take a manual dump of the coordinator and postman databases before any risky change.
