These 41fa9e4066Sahrens * individual routines do not have to do anything "stressful". 42fa9e4066Sahrens * 43fa9e4066Sahrens * (2) We turn these simple functionality tests into a stress test by 44fa9e4066Sahrens * running them all in parallel, with as many threads as desired, 45fa9e4066Sahrens * and spread across as many datasets, objects, and vdevs as desired. 46fa9e4066Sahrens * 47fa9e4066Sahrens * (3) While all this is happening, we inject faults into the pool to 48fa9e4066Sahrens * verify that self-healing data really works. 49fa9e4066Sahrens * 50fa9e4066Sahrens * (4) Every time we open a dataset, we change its checksum and compression 51fa9e4066Sahrens * functions. Thus even individual objects vary from block to block 52fa9e4066Sahrens * in which checksum they use and whether they're compressed. 53fa9e4066Sahrens * 54fa9e4066Sahrens * (5) To verify that we never lose on-disk consistency after a crash, 55fa9e4066Sahrens * we run the entire test in a child of the main process. 56fa9e4066Sahrens * At random times, the child self-immolates with a SIGKILL. 57fa9e4066Sahrens * This is the software equivalent of pulling the power cord. 58fa9e4066Sahrens * The parent then runs the test again, using the existing 595d7b4d43SMatthew Ahrens * storage pool, as many times as desired. If backwards compatibility 60420dfc95SChris Siden * testing is enabled ztest will sometimes run the "older" version 61420dfc95SChris Siden * of ztest after a SIGKILL. 62fa9e4066Sahrens * 63fa9e4066Sahrens * (6) To verify that we don't have future leaks or temporal incursions, 64fa9e4066Sahrens * many of the functional tests record the transaction group number 65fa9e4066Sahrens * as part of their data. When reading old data, they verify that 66fa9e4066Sahrens * the transaction group number is less than the current, open txg. 67fa9e4066Sahrens * If you add a new test, please do this if applicable. 68fa9e4066Sahrens * 69fa9e4066Sahrens * When run with no arguments, ztest runs for about five minutes and 70fa9e4066Sahrens * produces no output if successful. To get a little bit of information, 71fa9e4066Sahrens * specify -V. To get more information, specify -VV, and so on. 72fa9e4066Sahrens * 73fa9e4066Sahrens * To turn this into an overnight stress test, use -T to specify run time. 74fa9e4066Sahrens * 75fa9e4066Sahrens * You can ask more more vdevs [-v], datasets [-d], or threads [-t] 76fa9e4066Sahrens * to increase the pool capacity, fanout, and overall stress level. 77fa9e4066Sahrens * 78420dfc95SChris Siden * Use the -k option to set the desired frequency of kills. 79420dfc95SChris Siden * 80420dfc95SChris Siden * When ztest invokes itself it passes all relevant information through a 81420dfc95SChris Siden * temporary file which is mmap-ed in the child process. This allows shared 82420dfc95SChris Siden * memory to survive the exec syscall. The ztest_shared_hdr_t struct is always 83420dfc95SChris Siden * stored at offset 0 of this file and contains information on the size and 84420dfc95SChris Siden * number of shared structures in the file. The information stored in this file 85420dfc95SChris Siden * must remain backwards compatible with older versions of ztest so that 86420dfc95SChris Siden * ztest can invoke them during backwards compatibility testing (-B). 87fa9e4066Sahrens */ 88fa9e4066Sahrens 89fa9e4066Sahrens #include <sys/zfs_context.h> 90fa9e4066Sahrens #include <sys/spa.h> 91fa9e4066Sahrens #include <sys/dmu.h> 92fa9e4066Sahrens #include <sys/txg.h> 932fdbea25SAleksandr Guzovskiy #include <sys/dbuf.h> 94fa9e4066Sahrens #include <sys/zap.h> 95fa9e4066Sahrens #include <sys/dmu_objset.h> 96fa9e4066Sahrens #include <sys/poll.h> 97fa9e4066Sahrens #include <sys/stat.h> 98fa9e4066Sahrens #include <sys/time.h> 99fa9e4066Sahrens #include <sys/wait.h> 100fa9e4066Sahrens #include <sys/mman.h> 101fa9e4066Sahrens #include <sys/resource.h> 102fa9e4066Sahrens #include <sys/zio.h> 103fa9e4066Sahrens #include <sys/zil.h> 104b24ab676SJeff Bonwick #include <sys/zil_impl.h> 105fa9e4066Sahrens #include <sys/vdev_impl.h> 106e14bb325SJeff Bonwick #include <sys/vdev_file.h> 107094e47e9SGeorge Wilson #include <sys/vdev_initialize.h> 108fa9e4066Sahrens #include <sys/spa_impl.h> 10988ecc943SGeorge Wilson #include <sys/metaslab_impl.h> 110fa9e4066Sahrens #include <sys/dsl_prop.h> 1114f5064b7SMark J Musante #include <sys/dsl_dataset.h> 1123b2aab18SMatthew Ahrens #include <sys/dsl_destroy.h> 1133f9d6ad7SLin Ling #include <sys/dsl_scan.h> 114cde58dbcSMatthew Ahrens #include <sys/zio_checksum.h> 115fa9e4066Sahrens #include <sys/refcount.h> 116ad135b5dSChristopher Siden #include <sys/zfeature.h> 1173b2aab18SMatthew Ahrens #include <sys/dsl_userhold.h> 118770499e1SDan Kimmel #include <sys/abd.h> 119fa9e4066Sahrens #include <stdio.h> 120004388ebScasper #include <stdio_ext.h> 121fa9e4066Sahrens #include <stdlib.h> 122fa9e4066Sahrens #include <unistd.h> 123fa9e4066Sahrens #include <signal.h> 124fa9e4066Sahrens #include <umem.h> 125fa9e4066Sahrens #include <dlfcn.h> 126fa9e4066Sahrens #include <ctype.h> 127fa9e4066Sahrens #include <math.h> 128fa9e4066Sahrens #include <sys/fs/zfs.h> 129b24ab676SJeff Bonwick #include <libnvpair.h> 130e0f1c0afSOlaf Faaland #include <libzfs.h> 1310a055120SJason King #include <libcmdutils.h> 132fa9e4066Sahrens 133741652b0SEtienne Dechamps static int ztest_fd_data = -1;
