Support for Kafka over NFS via the ability to enable the ONTAP volume "-is-preserve-unlink-enabled" flag

Open arndt-netapp opened this issue 2 years ago • 2 comments

With ONTAP 9.12.1 and higher, NFSv4.1, and Linux changes that are in RHEL 8.7 or 9.1 and higher, there are fixes to support running Kafka over NFS. There are some details about this at https://www.netapp.com/blog/simplify-apache-kafka-confluent/.

In order to enable this functionality in ONTAP, there is a new volume setting in 9.12.1 called "-is-preserve-unlink-enabled", which must be set to "true". The ask is for Trident to provide a way for this setting to be enabled so that PVCs for Kafka can be created using the ontap-nas or ontap-nas-economy drivers.

We would definitely make use of this feature in our containerized Kafka deployments. Look forward to updates on when this can be available.

Is there anything new with this?

This is an important feature that will greatly increase the use-cases for trident
