will confusing the mapping algorithm.

The cache pools will throttle when they reach the target max size, so it
is important to make the administrator aware when they approach that point.
Unfortunately it is not particularly easy to efficiently keep track of
which PGs have hit their limit and use that for reporting. However, it
is easy to raise a flag when we start to approach the target for the
entire pool, and that sort of early warning is arguably more useful
anyway.
Trigger the warning based on the target full ratio. Not when we hit the
target, but when we are 2/3 between it and completely full.

This is a friendlier interface for setting up a cache tier with some
reasonable defaults (defined via config options). This will simplify
the user experience and documentation.

In general, users should not use non-empty pools as new tiers or else
things can behave strangely:
- the data sets are unrelated behavior will be... strange.
- if the cache pool is not "new" and does not do the OMAP flag, the OSD
will not know not to flush omap objects to an EC base tier
- probably other random stuff I'm forgetting
Allow a user to shoot themselves in the foot with --force-nonempty.

comment out erasure pool related tests when an OSD is involved because
it does not work yet. See http://tracker.ceph.com/issues/7360.

Now ObjectStore support three backend types, so we need to make each backend
share unit test to avoid duplicate codes.
This patch mainly make workload_generator workable for objectstore.

On Linux ENOTSUP is remapped
/usr/include/x86_64-linux-gnu/bits/errno.h
/* Linux has no ENOTSUP error code. */
# define ENOTSUP EOPNOTSUPP
and should have different values on other operating systems. On Ubuntu
precise the string returned when translating the error value of ENOTSUP
or EOPNOTSUPP is always EOPNOTSUPP but on Ubuntu saucy it is always
ENOTSUP.
Replace ENOSYS with ENOTSUP because the expected semantic is very
similar and modify the test to not check on the string translation of
the error.
Rework the check_response shell function to optionaly check the return
code. The erasure coded pool size change test verifies the error message
only but not the error code.

We had already added this as a flag (set/unset) when I generalized the
'mds set_max_mds' to be 'ceph mds set <var> <val>'. Switch the snaps
flag to be a key/value to with true/false (similar to the hashpspool
pool flag) since there are fewer users and the var/val approach is more
general.

When run in a shared environment ( as opposed as a machine created for
the purpose of running this test only ), it is important to cleanup
leftovers to avoid poluting the /tmp space. Create a common temporary
directory for all tmp files.

First, add the ability to modify max_file_size. While we are at it, move
to a more sensible interface for adjusting max_mds too.

This will show up on the command line and logs, making it more
