Add zimport.sh compatibility test script
Verify that an assortment of known good reference pools can be imported using different versions of the ZoL code. By default references pools for the major ZFS implementation will be checked against the most recent ZoL tags and the master development branch. Alternate tags or branches may be verified with the '-s <src-tag> option. Passing the keyword "installed" will instruct the script to test whatever version is installed. Preferentially a reference pool is used for all tests. However, if one does not exist and the pool-tag matches one of the src-tags then a new reference pool will be created using binaries from that source build. This is particularly useful when you need to test your changes before opening a pull request. New reference pools may be added by placing a bzip2 compressed tarball of the pool in the scripts/zpool-example directory and then passing the -p <pool-tag> option. To increase the test coverage reference pools should be collected for all the major ZFS implementations. Having these pools easily available is also helpful to the developers. Care should be taken to run these tests with a kernel supported by all the listed tags. Otherwise build failure will cause false positives. EXAMPLES: The following example will verify the zfs-0.6.2 tag, the master branch, and the installed zfs version can correctly import the listed pools. Note there is no reference pool available for master and installed but because binaries are available one is automatically constructed. The working directory is also preserved between runs (-k) preventing the need to rebuild from source for multiple runs. zimport.sh -k -f /var/tmp/zimport \ -s "zfs-0.6.2 master installed" \ -p "zevo-1.1.1 zol-0.6.2 zol-0.6.2-173 master installed" --------------------- ZFS on Linux Source Versions -------------- zfs-0.6.2 master 0.6.2-175_g36eb554 ----------------------------------------------------------------- Clone SPL Local Local Skip Clone ZFS Local Local Skip Build SPL Pass Pass Skip Build ZFS Pass Pass Skip ----------------------------------------------------------------- zevo-1.1.1 Pass Pass Pass zol-0.6.2 Pass Pass Pass zol-0.6.2-173 Fail Pass Pass master Pass Pass Pass installed Pass Pass Pass Signed-off-by: Brian Behlendorf <[email protected]> Issue openzfs#2094
