/*
* The objective of this program is to provide a DMU/ZAP/SPA stress test
* that runs entirely in userland, is easy to use, and easy to extend.
*
* The overall design of the ztest program is as follows:
*
* (1) For each major functional area (e.g. adding vdevs to a pool,
* creating and destroying datasets, reading and writing objects, etc)
* we have a simple routine to test that functionality. These
* individual routines do not have to do anything "stressful".
*
* (2) We turn these simple functionality tests into a stress test by
* running them all in parallel, with as many threads as desired,
* and spread across as many datasets, objects, and vdevs as desired.
*
* (3) While all this is happening, we inject faults into the pool to
* verify that self-healing data really works.
*
* (4) Every time we open a dataset, we change its checksum and compression
* functions. Thus even individual objects vary from block to block
* in which checksum they use and whether they're compressed.
*
* (5) To verify that we never lose on-disk consistency after a crash,
* we run the entire test in a child of the main process.
* At random times, the child self-immolates with a SIGKILL.
* This is the software equivalent of pulling the power cord.
* The parent then runs the test again, using the existing
* storage pool, as many times as desired.
*
* (6) To verify that we don't have future leaks or temporal incursions,
* many of the functional tests record the transaction group number
* as part of their data. When reading old data, they verify that
* the transaction group number is less than the current, open txg.
* If you add a new test, please do this if applicable.
*
* When run with no arguments, ztest runs for about five minutes and
* produces no output if successful. To get a little bit of information,
* specify -V. To get more information, specify -VV, and so on.
*
* To turn this into an overnight stress test, use -T to specify run time.
*
* You can ask more more vdevs [-v], datasets [-d], or threads [-t]
* to increase the pool capacity, fanout, and overall stress level.
*
* The -N(okill) option will suppress kills, so each child runs to completion.
* This can be useful when you're trying to distinguish temporal incursions
* from plain old race conditions.
