How can i verify that Real-Time-Replication works?

Hey,

i just set up a second server for Real Time replication but i don’t think that its syncing.
The server doesn’t produce any traffic.

Despite the Docs saying that seahub won’t work, it’s still accessible on my backup-server.

Here is what seaf-backup-cmd says:

# ./seaf-backup-cmd.sh status
Total number of libraries: 3
Number of synchronized libraries: 2
Number of libraries waiting for sync: 0
Number of libraries syncing: 1
Number of libraries failed to sync: 0

List of syncing libraries:
1bb62d1b-3751-47e5-8b1a-f243b546ac2b

List of libraries failed to sync:

And here is the seafile-log:

2021-11-28 12:22:25 http-tx-mgr.c(2182): Sync polling timer triggered, start to fetch repo list from primary.

How can i check if the sync actually works?
