schemaList.append(mySchema) UnboundLocalError: local variable 'mySchema' referenced before assignment

[Charlie Schluting ☃]

I created a storage-aggregation.conf file, with the following:
[default]
xFilesFactor = 0

With that, carbon-cache fails to start:
  File "/opt/graphite/lib/carbon/storage.py", line 186, in loadAggregationSchemas
    schemaList.append(mySchema)
UnboundLocalError: local variable 'mySchema' referenced before assignment

If I add:
pattern = ^.*$

...it works. I didn't notice the docs say pattern was required -- is it intended to be required?

Thanks much!

If you look at the storage-aggregation.conf.example file, you'll see that all of them have a pattern.
We strongly recommend using the examples as a base, and altering them to fit your needs rather than writing a new conf file from scratch.

Which docs didn't make it clear that a pattern was required?

Fair enough, I should have checked out the examples :)

I was reading the storage-aggregation section of:
http://graphite.readthedocs.org/en/latest/config-carbon.html

Thanks,
