This isn't the use case for most/all cluster file systems.   This is 
where distributed object systems and buckets rule.

Take your file, dump it into an S3 like bucket on one end, pull it out 
of the S3 like bucket on the other.  If you don't want to use get/put 
operations, then use s3fs/s3ql.  You can back this up with replicating 
EC minio stores (will take a few minutes to set up ... compare that to 

The down side to this is that minio has limits of about 16TiB last I 
checked.   If you need more, replace minio with another system (igneous, 
ceph, etc.).  Ping me offline if you want to talk more.
