/*
|
|
* 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. If backwards compatibility
|
|
* testing is enabled ztest will sometimes run the "older" version
|
|
* of ztest after a SIGKILL.
|
|
*
|
|
* (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.
|
|
*
|
|
* (7) Threads are created with a reduced stack size, for sanity checking.
|
|
* Therefore, it's important not to allocate huge buffers on the stack.
|
|
*
|
|
* 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 vdevs [-v], datasets [-d], or threads [-t]
|
|
* to increase the pool capacity, fanout, and overall stress level.
|
|
*
|
|
* Use the -k option to set the desired frequency of kills.
|
|
*
|
|
* When ztest invokes itself it passes all relevant information through a
|
|
* temporary file which is mmap-ed in the child process. This allows shared
|
|
* memory to survive the exec syscall. The ztest_shared_hdr_t struct is always
|
|
* stored at offset 0 of this file and contains information on the size and
|
|
* number of shared structures in the file. The information stored in this file
|
|
* must remain backwards compatible with older versions of ztest so that
|
|
* ztest can invoke them during backwards compatibility testing (-B).
