Sure.

True, with a catch: with the default data=ordered option, even ext4 does
*not* remount read only when data writeout fails. You need to use both
"errors=remount-ro" and "data=journal" which basically nobody uses.

Thanks for the input. So, do you run your ext4 filesystem with
data=journal? How they behave performane-wise?
Regards.
