2#
3# Verify that an assortment of known good reference pools can be imported
4# using different versions of OpenZFS code.
5#
6# By default references pools for the major ZFS implementation will be
7# checked against the most recent OpenZFS tags and the master development branch.
8# Alternate tags or branches may be verified with the '-s <src-tag> option.
9# Passing the keyword "installed" will instruct the script to test whatever
10# version is installed.
11#
12# Preferentially a reference pool is used for all tests.  However, if one
13# does not exist and the pool-tag matches one of the src-tags then a new
14# reference pool will be created using binaries from that source build.
15# This is particularly useful when you need to test your changes before
16# opening a pull request.  The keyword 'all' can be used as short hand
17# refer to all available reference pools.
18#
19# New reference pools may be added by placing a bzip2 compressed tarball
20# of the pool in the scripts/zfs-images directory and then passing
21# the -p <pool-tag> option.  To increase the test coverage reference pools
22# should be collected for all the major ZFS implementations.  Having these
23# pools easily available is also helpful to the developers.
24#
25# Care should be taken to run these tests with a kernel supported by all
26# the listed tags.  Otherwise build failure will cause false positives.
27#
28#
29# EXAMPLES:
30#
31# The following example will verify the zfs-0.6.2 tag, the master branch,
32# and the installed zfs version can correctly import the listed pools.
33# Note there is no reference pool available for master and installed but
34# because binaries are available one is automatically constructed.  The
35# working directory is also preserved between runs (-k) preventing the
36# need to rebuild from source for multiple runs.
