You can manually set the flag using debugfs:
# debugfs -w /dev/hdXX
debugfs: set_super_value s_flags 4
debugfs: quit
(Or, if you're lazy, you can also type the shorthand "ssv flags 4" to
debugfs.)
With e2fsprogs 1.40.5, if the test_fs flag is set, then blkid will
return a filesystem type ext4dev, such that if your mount is
configured to use blkid (instead of vol_id), it will automatically use
ext4dev to mount a filesystem that has (a) a journal (since ext4
currently requires a journal), and (b) the test_fs flag set.
This makes it easier for people who are testing ext4, since they will
just be able to do something like:
# mke2fs -j -E test_fs /dev/mapper/lvmset-test
# mount /dev/mapper/lvmset-test
.. and /dev/mapper/lvmset-test will automatically be mounted using
ext4.

thanks for your quick answer! i think i've learned something more about
ext4 and those flags.
