Shadow file do not works as expected

aerospike version: 3.15.1.4

configure:

# Aerospike database configuration file.

# This stanza must come first.
service {
  user admin
  group admin
  paxos-single-replica-limit 1 # Number of nodes where the replica count is automatically reduced to 1.

    context any info
  }

namespace ns1 {
    replication-factor 2

            filesize 4G
            data-in-memory true
            write-block-size 256K
        }
}

when I start server and write some data, I only can see the test.data file in /home/admin/aerospike/data, but the shadow file test2.dat do not exist in /home/admin/aerospike/data2.

Is there something some wrong?

From https://www.aerospike.com/docs/reference/configuration/ :

Data file path on rotational disk (using a file system) or pemem (as of version 4.8). As of 4.3.0.2, the file may include an optional ‘shadow file’ as a second argument.

Shadow files were not supported until 4.3.0.2.
