Environment

SUSE Enterprise Server 5.5

Situation

SES5.5: Stage.2 fails with "Exception occurred in runner advise.osds".

Below is an excerpt of the stage.2 output:
 
          ID: advise OSDs
    Function: salt.runner
        Name: advise.osds
      Result: False
     Comment: Exception occurred in runner advise.osds: Traceback (most recent call last):
                File "/usr/lib/python2.7/site-packages/salt/client/mixins.py", line 395, in _low

Resolution

Run the following command on the admin node:
# salt -I roles:storage osd.report human=False

Most likely a minion is not replying, causing stage.2 to fail. 

Example of success:
ceph-osd4:~ # salt -I roles:storage osd.report human=False
ceph-osd11.ceph.example.com:
    ----------
    changed:
    unconfigured:
    unmounted:
ceph-osd12.ceph.example.com:
    ----------
    changed:
    unconfigured:
    unmounted:
ceph-osd15.ceph.example.com:
    ----------
    changed:
    unconfigured:
    unmounted:
ceph-osd14.ceph.example.com:
    ----------
    changed:
    unconfigured:
    unmounted:
ceph-osd10.ceph.example.com:
    ----------
    changed:
    unconfigured:
    unmounted:
ceph-osd13.ceph.example.com:
    ----------
    changed:
    unconfigured:
    unmounted:

Each should report back the triplet of 'unconfigured', 'changed' and 'unmounted'.  
Example of a failure:
ceph-osd4:~ # salt -I roles:storage osd.report human=False
ceph-osd16.ceph.example.com:
   The minion function caused an exception: Traceback (most recent call
last):
     File "/usr/lib/python2.7/site-packages/salt/minion.py", line 1455,
in _thread_return
       return_data = executor.execute()
     File
"/usr/lib/python2.7/site-packages/salt/executors/direct_call.py", line
28, in execute
       return self.func(*self.args, **self.kwargs)
     File "/var/cache/salt/minion/extmods/modules/osd.py", line 2352,
in report
       un1, ch1 = _report_pillar(active)
     File "/var/cache/salt/minion/extmods/modules/osd.py", line 2412,
in _report_pillar
       unconfigured = __pillar__['ceph']['storage']['osds'].keys()
   KeyError: 'storage'

The remainder of the nodes report back as expected. 
In this case, this is a node that was removed out of the cluster in the past with the plan to reintroduce it to the cluster at some point in the future. 

Address the minion which is not responding, using the above example the minion in question is "ceph-osd16.ceph.example.com". In some cases, there may be an invalid minion key, which needs to removed.

List salt keys:
salt-key --list-all

Delete a salt key:
salt-key -d <minion_name>

In other cases, restarting the problem minion may resolve the issue. 

Cause

An OSD node was removed from the cluster, but the salt minion key for this node was not removed from the salt-master configuration.
