Pádraig, thanks for your response.
In my reproducer environment, it doesn't totally update. RHEL7 Samba server,
RHEL6 Samba client.
Unless I provided the extra interval parameter.
When I run it in Redhat9, I don't need any extra, it refresh automatically.

Could you clarify whether the rhel7 version of tail is too slow when showing
updates to the file, or misses updates to the file entirely.
There have been various fixes to tail, so it would be worth verifying how the
latest behaves, like:
wget https://ftpmirror.gnu.org/coreutils/coreutils-8.29.tar.xz
tar -xf coreutils-8.29.tar.xz
cd coreutils-8.29
./configure --quiet && make -j$(nproc)
src/tail -f /media/samba/test.file
cheers,
Pádraig
