How do I synchronize my gluster replicated volumes? - sqlite

Question

I want to use a gluster replication volume for sqlite db storage
However, when the '.db' file is updated, LINUX does not detect the change, so synchronization between bricks is not possible.
Is there a way to force sync?
It is not synchronized even if you use the gluster volume heal command.
< My Gluster volume status >
[root#be-k8s-worker-1 common]# gluster volume create sync_test replica 2 transport tcp 10.XX.XX.X1:/home/common/sync_test 10.XX.XX.X2:/home/common/sync_test
Replica 2 volumes are prone to split-brain. Use Arbiter or Replica 3 to avoid this. See: http://docs.gluster.org/en/latest/Administrator%20Guide/Split%20brain%20and%20ways%20to%20deal%20with%20it/.
Do you still want to continue?

## diff -> No result
[root#be-k8s-worker-1 user]# diff sync_test/test.db sync_test2/test.db
But if I compare same file in windows
compare on windows

My SQLite database was set to WAL mode. So the wal file was being updated and the .db file was not immediately synced.
I turned off WAL Mode with this command:
PRAGMA journal_mode=DELETE;
I confirmed that it was synced immediately.
According to Sqlite document, It doesn't work over a network file system.
All processes using a database must be on the same host computer; WAL does not work over a network filesystem.
