Regarding fio version fio-2.1.9-17-gd9b1 (after April 11, 2014):
A recent change (
5e1d8745471d1f315113c5c3fd8b93809d9ddff9) caused stdout
to be closed when -o was specified, which prevents ETA output from showing
up on stdout even when, e.g., json is being saved in the file.
This patch continues to close f_out so that there is no leak if multiple -o
options are specified, but doesn't close stdout. Hence, ETA works again
when it should.
