Build Status

blktests is a test framework for the Linux kernel block layer and storage stack. It is inspired by the xfstests filesystem testing framework.

Getting Started

The dependencies are minimal, but make sure you have them installed:

  • bash (>= 4.2)
  • GNU coreutils
  • GNU awk
  • util-linux
  • fio
  • gcc
  • make

Some tests require the following:

  • e2fsprogs and xfsprogs
  • multipath-tools (Debian, openSUSE, Arch Linux) or device-mapper-multipath (Fedora)
  • dmsetup (Debian) or device-mapper (Fedora, openSUSE, Arch Linux)

Build blktests with make. Optionally, install it to a known location with make install (/usr/local/blktests by default, but this can be changed by passing DESTDIR and/or prefix).

Add the list of block devices you want to test on in a file named config (note: these tests are potentially destructive):

TEST_DEVS=(/dev/nvme0n1 /dev/sdb)

And as root, run the default set of tests with ./check.

Do not add anything to the TEST_DEVS array containing data that you want to keep.

See here for more detailed information on configuration and running tests.

Adding Tests

The ./new script creates a new test from a template. The generated template contains more detailed documentation.

Pull requests on GitHub and patches to are both accepted. See here for more information on contributing.
