I'd say the NFS is not involved here in any special way. At least my tests with
NFS+ZFS confirmed the sparse attribute works as expected. So it really looks
like the SAM-FS does not support the sparse attribute. Are you able to
reproduce the issue on SAM-FS locally (i.e. without NFS)? Are you able to
reproduce the issue without SAM-FS?
