@ -82,6 +82,12 @@ You can run unit tests with ``.unittests``, functional tests with
``.functests``, and probe tests with ``.probetests``. There is an
additional ``.alltests`` script that wraps the other three.
To fully run the tests, the target environment must use a filesystem that
supports large xattrs. XFS is strongly recommended. For unit tests and in-
process functional tests, either mount ``/tmp`` with XFS or provide another
XFS filesystem via the ``TMPDIR`` environment variable. Without this setting,
tests should still pass, but a very large number will be skipped.

Creating an XFS tmp dir
-----------------------
Tests require having an XFS directory available in ``/tmp`` or in the
``TMPDIR`` environment variable. To set up ``/tmp`` with an XFS filesystem,
do the following::
cd ~
truncate -s 1GB xfs_file # create 1GB fil for XFS in your home directory
mkfs.xfs xfs_file
sudo mount -o loop,noatime,nodiratime xfs_file /tmp
sudo chmod -R 1777 /tmp
To persist this, edit and add the following to ``/etc/fstab``::
/home/swift/xfs_file /tmp xfs rw,noatime,nodiratime,attr2,inode64,noquota 0 0
