+ pattern Fill the IO buffers with a specific pattern,
+ that we can use to verify. Depending on the
+ width of the pattern, fio will fill 1/2/3/4
+ bytes of the buffer at the time. The pattern
+ cannot be larger than a 32-bit quantity. The
+ given pattern is given as a postfix to this
+ option, ala: verify=pattern:0x5a. It accepts

null Only pretend to verify. Useful for testing
internals with ioengine=null, not for much
else.
size of header_interval. blocksize should divide this
evenly.
-verify_pattern=int If set, fio will fill the io buffers with this
- pattern. Fio defaults to filling with totally random
- bytes, but sometimes it's interesting to fill with a known
- pattern for io verification purposes. Depending on the
- width of the pattern, fio will fill 1/2/3/4 bytes of the
- buffer at the time. The verify_pattern cannot be larger than
- a 32-bit quantity.

verify_fatal=bool Normally fio will keep checking the entire contents
before quitting on a block verification failure. If this
option is set, fio will exit the job on the first observed
