After reading over your configuration I believe I have found your problem. Individual devices and files in Aerospike can be no larger than 2TiB and yours are configured to 3TiB. Regrettably there currently isn’t a check in config parser for this limit and I am unable to find reference in our docs–both of these issues are being taken care of.
You can instead use multiple files to store your data for each namespace (each file limited to 2TB). As discussed elsewhere you will likely see better performance by using multiple files or devices for a given namespace.
