31 | /* |
32 | * The objective of this program is to provide a DMU/ZAP/SPA stress test | |
33 | * that runs entirely in userland, is easy to use, and easy to extend. | |
34 | * | |
35 | * The overall design of the ztest program is as follows: | |
36 | * | |
37 | * (1) For each major functional area (e.g. adding vdevs to a pool, | |
38 | * creating and destroying datasets, reading and writing objects, etc) | |
39 | * we have a simple routine to test that functionality. These | |
40 | * individual routines do not have to do anything "stressful". | |
41 | * | |
42 | * (2) We turn these simple functionality tests into a stress test by | |
43 | * running them all in parallel, with as many threads as desired, | |
44 | * and spread across as many datasets, objects, and vdevs as desired. | |
45 | * | |
46 | * (3) While all this is happening, we inject faults into the pool to | |
47 | * verify that self-healing data really works. | |
48 | * | |
49 | * (4) Every time we open a dataset, we change its checksum and compression | |
50 | * functions. Thus even individual objects vary from block to block | |
51 | * in which checksum they use and whether they're compressed. | |
52 | * | |
53 | * (5) To verify that we never lose on-disk consistency after a crash, | |
54 | * we run the entire test in a child of the main process. | |
55 | * At random times, the child self-immolates with a SIGKILL. | |
56 | * This is the software equivalent of pulling the power cord. | |
57 | * The parent then runs the test again, using the existing | |
9b67f605 | 58 | * storage pool, as many times as desired. If backwards compatibility |
c242c188 CS |
59 | * testing is enabled ztest will sometimes run the "older" version |
60 | * of ztest after a SIGKILL. | |
34dc7c2f BB |
61 | * |
62 | * (6) To verify that we don't have future leaks or temporal incursions, | |
63 | * many of the functional tests record the transaction group number | |
64 | * as part of their data. When reading old data, they verify that | |
65 | * the transaction group number is less than the current, open txg. | |
66 | * If you add a new test, please do this if applicable. | |
67 | * | |
1e33ac1e BB |
68 | * (7) Threads are created with a reduced stack size, for sanity checking. |
69 | * Therefore, it's important not to allocate huge buffers on the stack. | |
70 | * | |
34dc7c2f BB |
71 | * When run with no arguments, ztest runs for about five minutes and |
72 | * produces no output if successful. To get a little bit of information, | |
73 | * specify -V. To get more information, specify -VV, and so on. | |
74 | * | |
75 | * To turn this into an overnight stress test, use -T to specify run time. | |
76 | * | |
77 | * You can ask more more vdevs [-v], datasets [-d], or threads [-t] | |
78 | * to increase the pool capacity, fanout, and overall stress level. | |
79 | * | |
c242c188 CS |
80 | * Use the -k option to set the desired frequency of kills. |
81 | * | |
82 | * When ztest invokes itself it passes all relevant information through a | |
83 | * temporary file which is mmap-ed in the child process. This allows shared | |
84 | * memory to survive the exec syscall. The ztest_shared_hdr_t struct is always | |
85 | * stored at offset 0 of this file and contains information on the size and | |
86 | * number of shared structures in the file. The information stored in this file | |
87 | * must remain backwards compatible with older versions of ztest so that | |
88 | * ztest can invoke them during backwards compatibility testing (-B). | |
