These 40fa9e4066Sahrens * individual routines do not have to do anything "stressful". 41fa9e4066Sahrens * 42fa9e4066Sahrens * (2) We turn these simple functionality tests into a stress test by 43fa9e4066Sahrens * running them all in parallel, with as many threads as desired, 44fa9e4066Sahrens * and spread across as many datasets, objects, and vdevs as desired. 45fa9e4066Sahrens * 46fa9e4066Sahrens * (3) While all this is happening, we inject faults into the pool to 47fa9e4066Sahrens * verify that self-healing data really works. 48fa9e4066Sahrens * 49fa9e4066Sahrens * (4) Every time we open a dataset, we change its checksum and compression 50fa9e4066Sahrens * functions. Thus even individual objects vary from block to block 51fa9e4066Sahrens * in which checksum they use and whether they're compressed. 52fa9e4066Sahrens * 53fa9e4066Sahrens * (5) To verify that we never lose on-disk consistency after a crash, 54fa9e4066Sahrens * we run the entire test in a child of the main process. 55fa9e4066Sahrens * At random times, the child self-immolates with a SIGKILL. 56fa9e4066Sahrens * This is the software equivalent of pulling the power cord. 57fa9e4066Sahrens * The parent then runs the test again, using the existing 585d7b4d43SMatthew Ahrens * storage pool, as many times as desired. If backwards compatibility 59420dfc95SChris Siden * testing is enabled ztest will sometimes run the "older" version 60420dfc95SChris Siden * of ztest after a SIGKILL. 61fa9e4066Sahrens * 62fa9e4066Sahrens * (6) To verify that we don't have future leaks or temporal incursions, 63fa9e4066Sahrens * many of the functional tests record the transaction group number 64fa9e4066Sahrens * as part of their data. When reading old data, they verify that 65fa9e4066Sahrens * the transaction group number is less than the current, open txg. 66fa9e4066Sahrens * If you add a new test, please do this if applicable. 67fa9e4066Sahrens * 68fa9e4066Sahrens * When run with no arguments, ztest runs for about five minutes and 69fa9e4066Sahrens * produces no output if successful. To get a little bit of information, 70fa9e4066Sahrens * specify -V. To get more information, specify -VV, and so on. 71fa9e4066Sahrens * 72fa9e4066Sahrens * To turn this into an overnight stress test, use -T to specify run time. 73fa9e4066Sahrens * 74fa9e4066Sahrens * You can ask more more vdevs [-v], datasets [-d], or threads [-t] 75fa9e4066Sahrens * to increase the pool capacity, fanout, and overall stress level. 76fa9e4066Sahrens * 77420dfc95SChris Siden * Use the -k option to set the desired frequency of kills. 78420dfc95SChris Siden * 79420dfc95SChris Siden * When ztest invokes itself it passes all relevant information through a 80420dfc95SChris Siden * temporary file which is mmap-ed in the child process. This allows shared 81420dfc95SChris Siden * memory to survive the exec syscall. The ztest_shared_hdr_t struct is always 82420dfc95SChris Siden * stored at offset 0 of this file and contains information on the size and 83420dfc95SChris Siden * number of shared structures in the file. The information stored in this file 84420dfc95SChris Siden * must remain backwards compatible with older versions of ztest so that 85420dfc95SChris Siden * ztest can invoke them during backwards compatibility testing (-B). 86fa9e4066Sahrens */ 87fa9e4066Sahrens 88fa9e4066Sahrens #include <sys/zfs_context.h> 89fa9e4066Sahrens #include <sys/spa.h> 90fa9e4066Sahrens #include <sys/dmu.h> 91fa9e4066Sahrens #include <sys/txg.h> 922fdbea25SAleksandr Guzovskiy #include <sys/dbuf.h> 93fa9e4066Sahrens #include <sys/zap.h> 94fa9e4066Sahrens #include <sys/dmu_objset.h> 95fa9e4066Sahrens #include <sys/poll.h> 96fa9e4066Sahrens #include <sys/stat.h> 97fa9e4066Sahrens #include <sys/time.h> 98fa9e4066Sahrens #include <sys/wait.h> 99fa9e4066Sahrens #include <sys/mman.h> 100fa9e4066Sahrens #include <sys/resource.h> 101fa9e4066Sahrens #include <sys/zio.h> 102fa9e4066Sahrens #include <sys/zil.h> 103b24ab676SJeff Bonwick #include <sys/zil_impl.h> 104fa9e4066Sahrens #include <sys/vdev_impl.h> 105e14bb325SJeff Bonwick #include <sys/vdev_file.h> 106fa9e4066Sahrens #include <sys/spa_impl.h> 10788ecc943SGeorge Wilson #include <sys/metaslab_impl.h> 108fa9e4066Sahrens #include <sys/dsl_prop.h> 1094f5064b7SMark J Musante #include <sys/dsl_dataset.h> 1103b2aab18SMatthew Ahrens #include <sys/dsl_destroy.h> 1113f9d6ad7SLin Ling #include <sys/dsl_scan.h> 112cde58dbcSMatthew Ahrens #include <sys/zio_checksum.h> 113fa9e4066Sahrens #include <sys/refcount.h> 114ad135b5dSChristopher Siden #include <sys/zfeature.h> 1153b2aab18SMatthew Ahrens #include <sys/dsl_userhold.h> 116770499e1SDan Kimmel #include <sys/abd.h> 117fa9e4066Sahrens #include <stdio.h> 118004388ebScasper #include <stdio_ext.h> 119fa9e4066Sahrens #include <stdlib.h> 120fa9e4066Sahrens #include <unistd.h> 121fa9e4066Sahrens #include <signal.h> 122fa9e4066Sahrens #include <umem.h> 123fa9e4066Sahrens #include <dlfcn.h> 124fa9e4066Sahrens #include <ctype.h> 125fa9e4066Sahrens #include <math.h> 126fa9e4066Sahrens #include <sys/fs/zfs.h> 127b24ab676SJeff Bonwick #include <libnvpair.h> 1280a055120SJason King #include <libcmdutils.h> 129fa9e4066Sahrens 130741652b0SEtienne Dechamps static int ztest_fd_data = -1;
