Bug description:
Example of this here:
http://logs.openstack.org/33/97233/1/check/check-grenade-
dsvm/f7b8a11/logs/old/screen-n-cpu.txt.gz?level=TRACE#_2014-06-02_14_13_51_125
File "/opt/stack/old/nova/nova/compute/manager.py", line 4153, in
_detach_volume
connection_info = jsonutils.loads(bdm.connection_info)
File "/opt/stack/old/nova/nova/openstack/common/jsonutils.py", line 164,
in loads
return json.loads(s)
File "/usr/lib/python2.7/json/__init__.py", line 326, in loads
return _default_decoder.decode(s)
File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
TypeError: expected string or buffer
and this was in grenade with stable/icehouse nova commit 7431cb9
There's nothing unusual about the test which triggers this - simply
attaches a volume to an instance, waits for it to show up in the
instance and then tries to detach it
logstash query for this:
message:"Exception during message handling" AND message:"expected
string or buffer" AND message:"connection_info =
jsonutils.loads(bdm.connection_info)" AND tags:"screen-n-cpu.txt"
but it seems to be very rare
