There are several options:
1. Set the "pre-xfer exec = /script/name" in your daemon module and make
the script check if a /mnt/DATA/known-to-exist-subdir is missing and if so,
do an "exit 1".
2. If your server rsync is at least 3.2.1, set the "early exec =
/script/name" in your daemon module and make the script verify that the
drive is mounted & attempt to mount it if it is not (return an error code
if unable to mount it). The mount action is not possible in the pre-xfer
exec script because rsync has already done a chdir to the empty mount by
the time this script runs.
3. Move everything down into a deeper directory and tweak the path in
your daemon module to be "path = /mnt/DATA/subdir" so that the transfer
will fail when the mount is not there (because the subdir is not there).
