EFS custom attributes

0

Is it possible in EFS to store custom attributes (metadata) on a file? I've tried without any namespace and with the "user" namespace but I keep getting "Operation not supported".

sudo setfattr -n user.metadataName -v metadataValue efs/file.extension      
setfattr: efs/file.extension: Operation not supported

If this is not possible, is there a list of standard attributes that I can eventually exploit for my use case?

Although Amazon Elastic File System doesn't support NFSv2, or NFSv3, Amazon EFS supports both NFSv4.1 and NFSv4.0, except for the following features / attributes: https://docs.aws.amazon.com/efs/latest/ug/limits.html#nfs4-unsupported-features
