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:

What have you been doing here ?
Have you used 'live' thin-pool metadata for resize ?
(i.e. you were operating with active thin-pool volume,
while using command thin_repair on _tmeta device ?
You could eventually try to vgcfgbackup your VG,
manually edit pool's transaction id to match kernel number,
but you've been warned - that there were most probably
6 other transaction which are lost ?
This may also mean - the changes in chunks are also lost -
so if your volumes were allocating/releasing chunks - it's all lost
(depending on what have you been doing - hard to guess...)
You should be able to active pool with matching transaction_id,
but it's somewhat unpredictable if all LVs will have the right content.
(restore operation is going to be improved to add more validation)
