Reg thin pool activation failure - transaction id mismatch

Hi Team,
Good day all!

In yet another long testing run, I see a thin pool was unable to get
volume group thin pool activated.
vgchange -ay <vgname> fails with

```
/# vgchange -ay pwx3
Thin pool pwx3-pxpool-tpool (253:25) transaction_id is 6, while expected 24.
Thin pool pwx3-pxpool-tpool (253:25) transaction_id is 6, while expected 24.
Thin pool pwx3-pxpool-tpool (253:25) transaction_id is 6, while expected 24.
Thin pool pwx3-pxpool-tpool (253:25) transaction_id is 6, while expected 24.
3 logical volume(s) in volume group "pwx3" now active
```
It had other non thin lvols in the vg that got activated successfully.

I tried fixing the pool, by trying the following ``` lvconvert
--repair pwx3 ``` but this fails to fix the thin pool.

There was last configuration in the lvm config backup location.
I fixed the transaction id and used `vgcfgrestore --force -f <patched
config> pwx3` and this fixed the transaction id issue and vg was now
successfully activated.


And my follow up questions are:
1/ what exactly is a transaction id mismatch problem?
A little more detail about this problem will help me understand this better.

2/ Are there any known workflows that are known to create this issue?
So I can be careful to avoid such workflows.

3/ does recovery as above guarantee data in the pool? or is the pool
data suspect?

My environment is as below where the problem got seen:
