[linux-lvm] Cannot activate thin volumes. are they lost forever?

Greetings. As mentioned previously, I may have ruined all thin volumes
on a thin pool of mine due to the metadata overflow problem.

I am running LVM version 2.02.98 on kernel 3.11.0-19-generic.

I managed to compile LVM version 2.02.99 in order to get the metadata
resize feature as described in the ChangeLog:

  "Add lvresize support for online thin pool metadata volume resize."

I performed the metadata resize which seemed to work fine, but none of
my thin volumes will activate.

I would like to know whether the thin volumes are recoverable or not,
but I have been unable to determine my next step. Here's what I have
so far:
