The function get_dev_dir(self, match=None ) in euinstance.py not work.

Hi:
when i do snapshot test, I found the get_dev_dir() can't get the devices. I add some code to print the return value of get_dev_dir(), I saw the return value are "[ ]". print "before attach", print before_attach, print "after attach", print after_attach are added by me. In log you can see there only print two "[ ]". so may be the function get_dev_dir(self, match=None ) is not work. thanks!
my source code:

def createVolume1(self,instance,size=2):
'''
Create a volume and attach it to an instance,crean a txt file in it
'''
assert(instance is not None)
self.volume1 = self.tester.create_volume(instance.placement, size)
device_path = "/dev/" + instance.block_device_prefix +"j"
before_attach = instance.get_dev_dir()
#this line is added by zhangjian for debug
print "before attach"
print before_attach
try:
assert(self.tester.attach_volume(instance, self.volume1, device_path,timeout=180)==True)
except AssertionError, e:
assert(self.__deleteVolume(self.volume1,timeout=180)==True)
self.volome1 = None
return False
after_attach = instance.get_dev_dir()
print "after attach"
print after_attach
new_devices = self.tester.diff(after_attach, before_attach)
if len(new_devices) is 0:
return False
self.volume_device1 = "/dev/" + new_devices[0].strip()
instance.assertFilePresent(self.volume_device1)

    # create filesystem for volum1
    instance.sys("mkfs -t ext2 " +self.volume_device1)        
    # create mnt dir
    instance.sys("mkdir "+self.volume_mnt1)
    # mount volume1
    instance.sys("mount -t ext2 "+self.volume_device1 +" "+ self.volume_mnt1)
    # create a file in the volume
    instance.sys("touch "+self.volume_mnt1+"/"+self.testfilename)
    instance.sys("echo HelloWorld! >" +self.volume_mnt1+"/"+self.testfilename)
    # umount the volume
    instance.sys("umount "+self.volume_device1)
    # detach the volume
    self.tester.detach_volume(self.volume1,timeout=180)
    self.tester.sleep(5)
    return True

my test log:
