Jens,
I still see some verify errors when I set 'experimental_verify=1'

However, without this line, there are no verify errors anymore.
The fio file is:
[stress]
filename=/tmp/test
size=107374182
readwrite=randrw
bssplit=4k/50:1M/50
;bs=64k
do_verify=1
experimental_verify=1
verify=meta
verify_interval=64k
verify_dump=1
continue_on_error=verify
I'll look into the experimental_verify bit - there's a reason it's
experimental :-). But the hope is to make that the method for
verification, so I'll look into what goes wrong there. It might be
highlighting problems elsewhere (like accidental overwrites, due to the
mixed block sizes).
