The simplest way is probably to:
- move any files/directories of /mnt/DATA in a subdir.
Example: /mnt/DATA/data
- change rsyncd.conf to reflect that
I will do:
1. stop the rsync daemon on the server
2. do the move (assuming you have no files matching .?)
cd /mnt/DATA/
mkdir .a
mv * .??* .a
mv .a data
3. change rsyncd.conf: path = /mnt/DATA/data
4. start the rsync daemon
5. check in dry-run on one client:
- with /mnt/DATA mounted
- with /mnt/DATA unmounted
