I am currently using Trident Operator version 100.2502.1 with the default mount options, which defaults to NFSv4.2. During deployment, I observed that some applications failed to start due to NFS mount hang issues, particularly when the pods were configured with a subPath.
To troubleshoot, I updated the Trident backend configuration to version 4.0, which successfully resolved the NFS hang issue.
I’d like to understand whether any additional configuration is required at the storage level to ensure optimal performance and stability when using NFSv4.2 with Trident ONTAP-NAS.

With hangs, always check for mtu mismatch
