Anyway - 6.8 will likely be your solution.
Thin-provisioning is NOT supposed to be used at 'corner' cases - we improve
them, but older version simply had more of them as there was always clearly
communicated do not over-provision if you can't provide the space.
Out-of-space is not equal if you run out of your filesystem space - you can't
expect things will continue to work nicely - the cooperation of block layer
with filesystem and metadata resilience are continually improved.
We have actually even seen users 'targeting' to hit full-pool as a part of
regular work-flow - bad bad plan...
