Re: XFS Tests for Btrfs

Hi,

Xfstests uses several environment variants to setup the test environment.
You can set it manually using export, or write them into local.conf in 
xfstests directory.

These environment variants are mandatory:
TEST_DEV: device for normal tests, like all generic tests
TEST_DIR: where TEST_DEV is mounted to.

And somecommon optional environment variants:
SCRATCH_DEV: scratch device for some tests, if you want to test btrfs' 
multi device related feature, you need
to set SCRATCH_DEV_POOL.
SCRATCH_DEV_POOL: a list for devices mainly for btrfs' muti-device 
related test.
SCRATCH_MNT: where SCRATCH_DEV/SCRATCH_DEV_POOL is mounted to.

SCRATCH_DEV_POOL should not contain the TEST_DEV.

FSTYP: the filesystem type you want to test.
MKFS_OPTIONS: the mkfs time options. Useful to test mkfs time feature 
like no-holes.
MOUNT_OPTIONS: the mount time options. Useful to test feature like compress.

So short guide on how to run xfstests:
1. download the xfstests source, better the git version

2. compile xfstests
make will do everything for you, except you lacks some headers or 
dependency.
When that happens, follow your distribution's method to install them.

3. setup the environment variants
Manually or into the local.conf is both OK.

4. run tests
You can run all tests by ./check -g auto, or multiple/single test using 
blob/testcase number like:
# ./check generic/311
# ./check btrfs/[0-9][0-9][0-9]

Thanks
Qu
