blktests is a test framework for the Linux kernel block layer and storagestack. It is inspired by thexfstestsfilesystem testing framework.
The dependencies are minimal, but make sure you have them installed:
- bash 4
- GNU coreutils
- GNU awk
- util-linux
- fio
- gcc
- make
Some tests require the following:
- e2fsprogs and xfsprogs
- multipath-tools (Debian, openSUSE) or device-mapper-multipath (Fedora)
- dmsetup (Debian) or device-mapper (Fedora, openSUSE, Arch Linux)
Add the list of block devices you want to test on in a file namedconfig:
TEST_DEVS=(/dev/nvme0n1 /dev/sdb)
And as root, run the default set of tests with./check.
Note that these tests are destructive, so don't add anything to theTEST_DEVSarray containing data that you want to keep.
Seehere for more detailed information onconfiguration and running tests.
The./new script creates a new test from a template. The generated templatecontains more detailed documentation.
