25 | /* |
26 | * The objective of this program is to provide a DMU/ZAP/SPA stress test | |
27 | * that runs entirely in userland, is easy to use, and easy to extend. | |
28 | * | |
29 | * The overall design of the ztest program is as follows: | |
30 | * | |
31 | * (1) For each major functional area (e.g. adding vdevs to a pool, | |
32 | * creating and destroying datasets, reading and writing objects, etc) | |
33 | * we have a simple routine to test that functionality. These | |
34 | * individual routines do not have to do anything "stressful". | |
35 | * | |
36 | * (2) We turn these simple functionality tests into a stress test by | |
37 | * running them all in parallel, with as many threads as desired, | |
38 | * and spread across as many datasets, objects, and vdevs as desired. | |
39 | * | |
40 | * (3) While all this is happening, we inject faults into the pool to | |
41 | * verify that self-healing data really works. | |
42 | * | |
43 | * (4) Every time we open a dataset, we change its checksum and compression | |
44 | * functions. Thus even individual objects vary from block to block | |
45 | * in which checksum they use and whether they're compressed. | |
46 | * | |
47 | * (5) To verify that we never lose on-disk consistency after a crash, | |
48 | * we run the entire test in a child of the main process. | |
49 | * At random times, the child self-immolates with a SIGKILL. | |
50 | * This is the software equivalent of pulling the power cord. | |
51 | * The parent then runs the test again, using the existing | |
52 | * storage pool, as many times as desired. | |
53 | * | |
54 | * (6) To verify that we don't have future leaks or temporal incursions, | |
55 | * many of the functional tests record the transaction group number | |
56 | * as part of their data. When reading old data, they verify that | |
57 | * the transaction group number is less than the current, open txg. | |
58 | * If you add a new test, please do this if applicable. | |
59 | * | |
60 | * When run with no arguments, ztest runs for about five minutes and | |
61 | * produces no output if successful. To get a little bit of information, | |
62 | * specify -V. To get more information, specify -VV, and so on. | |
63 | * | |
64 | * To turn this into an overnight stress test, use -T to specify run time. | |
65 | * | |
66 | * You can ask more more vdevs [-v], datasets [-d], or threads [-t] | |
67 | * to increase the pool capacity, fanout, and overall stress level. | |
68 | * | |
69 | * The -N(okill) option will suppress kills, so each child runs to completion. | |
70 | * This can be useful when you're trying to distinguish temporal incursions | |
71 | * from plain old race conditions. | |
