Hi,

I want to mount an uncrypted AWS EFS in AWS Databricks. When I do:

mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport fs-abcdef.efs.region.amazonaws.com:/ /mnt/efs-uncrypted

I get this error:

mount.nfs4: mount(2): Permission denied
mount.nfs4: access denied by server while mounting fs-abcdef.efs.region.amazonaws.com:/
mount.nfs4: timeout set for Wed Nov  2 15:14:35 2022
mount.nfs4: trying text-based options 'nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport,addr=...,clientaddr=...'

I have made sure my EFS is in the same Availability Zone and the same VPC as the EC2 created by Databricks.

Do you have ideas about what I could set up or configure to successfully mount my EFS?

If you need further information, please let me know.

I wish you a good day.
