My task starts up and checks the mounted EFS volume for x data, if x data does not exist there, it then pulls x data from S3.

BoredHedgehog47 you can just use StorageManager and configure clearml cache for the EFS, it will essentially do the same 🙂
Regrading helm chart with EFS,
you need to configure the clearml-glue pod template with the EFS mount
example :
https://github.com/kubernetes-sigs/aws-efs-csi-driver/blob/e7f647f4e6fc76f983d61522e635353005f1472f/examples/kubernetes/volume_path/specs/example.yaml#L18
Then you need to point clearml cache to the mount point by setting the env var CLEARML_CACHE_DIR
wdyt?
