Backup Grafana in Kubernetes system - pod KO after restart

Hello
following topic How to backup Grafana in Kubernetes system
grafana pod is in error after I stop it for backup

  • probe failed
  • err: Failed to establish a new connection: [Errno 111] Connection refused’)': /api/admin/provisioning/dashboards/reload”

Do you please have an idea why ?

notes:

  • grafana helm 7.2.5 with openshift 4.12
  • I stop pod by scaling down and scaling up deployment
  • remediation:If I kill grafana pod, then it works OK

thank you for your help!

I have this log
logger=sqlstore.transactions level=info msg=“Database locked, sleeping then retrying” error=“database is locked” code=“database is locked”

the sqlite db seems OK
(pragma integrity_check;)

I found the problem: it was a short timeout for a readiness probe
