Hi,
I've noticed that when running fio in server mode it's not possible to
get a dump of using verify_dump when a verify mismatch occurs. Is it
possible to add a mode where the server process saves the mismatch
files to its current working directory for inspection later?
That sounds like an oversight. To save time, can you let me know how you
are invoking fio and with what job file? Should not be that hard to
fixup, it should just work.
Just tested this, and the fio backend does dump the files if
verify_dump=1 is set:
[...]
<lenny> write3: (g=0): rw=randread, bs=4K-4K/4K-4K/4K-4K, ioengine=sync,
iodepth=1
<lenny> Starting 1 process
<lenny> crc16: verify failed at file file offset 2023424, length 4096
<lenny> Expected CRC: 5b54
<lenny> Received CRC: c1aa
<lenny> received data dumped as file.2023424.received
<lenny> expected data dumped as file.2023424.expected
