The following kernel commit: commit e9072d859df3 ("ext4: prevent data corruption with journaling + DAX") makes "chattr +j", which is attempting to turn on data journaling, return -EBUSY if the ext4 DAX mount option is in use. This was done to prevent the data corruption shown in xfstest ext4/030, added by this xfstests commit: commit 750a24e99e48 ("ext4: test for DAX + journaling corruption") So, just skip shared/272 if the DAX mount option is in use.
