Bad sample on wiki page

[brettjacobson]

The sample presented on the wiki for "Mix random and sequential workloads (20% random and 80% sequential I/O)" results in an error:

ERROR: use -r to specify IO alignment when using mixed random/sequential IO (-rs)

Adding any kind of -r option results in:

ERROR: sequential IO (-s) conflicts with random IO (-r/-rs)

Is there a way to execute a mix of sequential and random workloads?

Sorry for the delay seeing this. That was a typo on the example - the -s8b should have been -r8b. I've fixed the text.
