Hi,
Does the verify option work with mixed read/write case, like rw or randrw ?
It's not clear from the help text (pasted below).
This option can be used for repeated burn-in tests of a
system to make sure that the written data is also
correctly read back. If the data direction given is
a read or random read, fio will assume that it should
verify a previously written file. If the data direction
includes any form of write, the verify will be of the
newly written data.
Thanks,
Vikram.
