1 # ZFS Test Suite README
3 1) Building and installing the ZFS Test Suite
5 The ZFS Test Suite runs under the test-runner framework. This framework
6 is built along side the standard ZFS utilities and is included as part of
7 zfs-test package. The zfs-test package can be built from source as follows:
12 The resulting packages can be installed using the rpm or dpkg command as
13 appropriate for your distributions. Alternately, if you have installed
14 ZFS from a distributions repository (not from source) the zfs-test package
15 may be provided for your distribution.
17 - Installed from source
18 $ rpm -ivh ./zfs-test*.rpm, or
19 $ dpkg -i ./zfs-test*.deb,
21 - Installed from package repository
22 $ yum install zfs-test
23 $ apt-get install zfs-test
25 2) Running the ZFS Test Suite
27 The pre-requisites for running the ZFS Test Suite are:
30 * Specify the disks you wish to use in the $DISKS variable, as a
31 space delimited list like this: DISKS='vdb vdc vdd'. By default
32 the zfs-tests.sh script will construct three loopback devices to
33 be used for testing: DISKS='loop0 loop1 loop2'.
34 * A non-root user with a full set of basic privileges and the ability
35 to sudo(8) to root without a password to run the test.
36 * Specify any pools you wish to preserve as a space delimited list in
37 the $KEEP variable. All pools detected at the start of testing are
39 * The ZFS Test Suite will add users and groups to test machine to
40 verify functionality. Therefore it is strongly advised that a
41 dedicated test machine, which can be a VM, be used for testing.
43 Once the pre-requisites are satisfied simply run the zfs-tests.sh script:
45 $ /usr/share/zfs/zfs-tests.sh
47 Alternately, the zfs-tests.sh script can be run from the source tree to allow
48 developers to rapidly validate their work. In this mode the ZFS utilities and
49 modules from the source tree will be used (rather than those installed on the
50 system). In order to avoid certain types of failures you will need to ensure
51 the ZFS udev rules are installed. This can be done manually or by ensuring
52 some version of ZFS is installed on the system.
54 $ ./scripts/zfs-tests.sh
56 The following zfs-tests.sh options are supported:
58 -v Verbose zfs-tests.sh output When specified additional
59 information describing the test environment will be logged
60 prior to invoking test-runner. This includes the runfile
61 being used, the DISKS targeted, pools to keep, etc.
63 -q Quiet test-runner output. When specified it is passed to
64 test-runner(1) which causes output to be written to the
65 console only for tests that do not pass and the results
68 -x Remove all testpools, dm, lo, and files (unsafe). When
69 specified the script will attempt to remove any leftover
70 configuration from a previous test run. This includes
71 destroying any pools named testpool, unused DM devices,
72 and loopback devices backed by file-vdevs. This operation
73 can be DANGEROUS because it is possible that the script
74 will mistakenly remove a resource not related to the testing.
76 -k Disable cleanup after test failure. When specified the
77 zfs-tests.sh script will not perform any additional cleanup
78 when test-runner exists. This is useful when the results of
79 a specific test need to be preserved for further analysis.
81 -f Use sparse files directly instead of loopback devices for
82 the testing. When running in this mode certain tests will
83 be skipped which depend on real block devices.
85 -c Only create and populate constrained path
87 -I NUM Number of iterations
89 -d DIR Create sparse files for vdevs in the DIR directory. By
90 default these files are created under /var/tmp/.
92 -s SIZE Use vdevs of SIZE (default: 4G)
94 -r RUNFILES Run tests in RUNFILES (default: common.run,linux.run)
96 -t PATH Run single test at PATH relative to test suite
98 -T TAGS Comma separated list of tags (default: 'functional')
100 -u USER Run single test as USER (default: root)
103 The ZFS Test Suite allows the user to specify a subset of the tests via a
104 runfile or list of tags.
106 The format of the runfile is explained in test-runner(1), and
107 the files that zfs-tests.sh uses are available for reference under
108 /usr/share/zfs/runfiles. To specify a custom runfile, use the -r option:
110 $ /usr/share/zfs/zfs-tests.sh -r my_tests.run
112 Otherwise user can set needed tags to run only specific tests.
116 While the ZFS Test Suite is running, one informational line is printed at the
117 end of each test, and a results summary is printed at the end of the run. The
118 results summary includes the location of the complete logs, which is logged in
119 the form `/var/tmp/test_results/[ISO 8601 date]`. A normal test run launched
120 with the `zfs-tests.sh` wrapper script will look something like this:
122 $ /usr/share/zfs/zfs-tests.sh -v -d /tmp/test
