Jens, I still see some verify errors when I set 'experimental_verify=1' verify: bad magic header 977c, wanted acca at file /tmp/test offset 15478784, length 429437046 verify: bad magic header 8aac, wanted acca at file /tmp/test offset 28082176, length 302426815 verify: bad magic header c8ad, wanted acca at file /tmp/test offset 30408704, length 318473336 verify: bad magic header 3791, wanted acca at file /tmp/test offset 65024000, length 74750452 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).
