Whenever I attach a PV, the database creation process always gets stuck, but if I don't use a PV, the deployment is successful. Thanks dp

From your initial report, I see that you're using NFS as your backing storage. NFS volumes in OpenShift are tricky as OpenShift pods run with restricted privileges and non-root UIDs. This means you have to match the GID/UID with the values of the NFS export.

For more information, see the OpenShift documentation on this topic: https://docs.openshift.com/container-platform/4.16/storage/persistent_storage/persistent-storage-nfs.html#nfs-volume-security_persistent-storage-nfs

Hello @theSuess So, what are the best practices for deploying Grafana with persistent volume on OpenShift? Can you please help?

[theSuess]

You need to ensure the permissions between the NFS share and the deployment match. This is not something we can give guidance on, as every NFS setup will be different. The prefered method to use persistent volumes is using CSI drivers. When using those, OpenShift will take care of the permission management for you.

If you decide to stick with NFS, you can use the deployment overrides to supply supplemental groups and modify the security context or match the namespace GID on your NFS server. This is a general OpenShift issue, not operator specific.

Thanks so much, @theSuess I'll try again to suggest from you.
