--- Comment #2 from wermaan@gmail.com --- In the end it's not a Wine issue. Seems to be an issue in the kernel, see https://www.spinics.net/lists/linux-fsdevel/msg116442.html. It can be resolved by create ZFS zubvolume and setting a quota for it (e.g. 1TB) - https://docs.oracle.com/cd/E19253-01/819-5461/gazvb/index.html.
