Error message provides faulty instructions and a 404 link

[Dmole]

Describe the bug

1. a 404 link.
2. config=notification does not make filer.toml.
3. both toml files are in current directory why are they not loaded?

System Setup

Expected behavior
A clear and concise description of what is required.

Please follow this example and add a filer.toml file to current directory, or $HOME/.seaweedfs/, or /etc/seaweedfs/:
    https://github.com/chrislusf/seaweedfs/blob/master/weed/notification.toml

Or use this command to generate the default toml file
    weed scaffold -config=notification -output=.

replication.toml

Side question: How do I get the mount points to sync?

[chrislusf]

1. need to generate notification.toml, used by weed filer to emit file change notifications.
2. need to generate replication.toml, used by weed replicate, to receive the notifications, and replicate data to the destination.

There are client side cache for weed mount. One file change would not be instantly visible until the file is closed. So do not expect instantaneous synchronization.

Thanks I missed that I had to run 3;

> ./weed scaffold -config=replication -output=.
> ./weed scaffold -config=filer -output=.
> ./weed scaffold -config=notification -output=.

Are you going to fix that 404 link?
https://github.com/chrislusf/seaweedfs/blob/master/weed/notification.toml

If this;

echo test > /opt/seaweedfs-mount/test.txt
./weed filer.replicate

won't sync a file what will?

[chrislusf]

weed filer.replicate would replicate the file to another seaweedfs cluster, or s3/azure/google_cloud_storage.
