[sheepdog] [PATCH v2 0/2] don't remove objects when they might be necessary

[MORITA Kazutaka]

Changes from v1:
 - move all objects in the working directory to the stale directory in
   purge_obj()


This series depends on
http://lists.wpkg.org/pipermail/sheepdog/2012-August/006322.html

We shouldn't remove objects until object recovery completely finishes.
With this patch, even if we wrongly stop more sheeps than the
redundancy level at the same time, sheepdog can recover objects
automatically after they start up.  Even if sheepdog crashes
unexpectedly, we can recover objects from the stale directory manually
at worst.


MORITA Kazutaka (2):
  tests: add test to check recovery after many nodes failed
  store: make objects stale when sheep starts
