Problem with LVM Thin Metadata Full

[Pongtawat]

(I'm sorry if this is out of scope of this forum, but I hope some experts here might be able to help me)

I'm having a problem with LVM Thin Pool and Volume. After the metadata full and my attempt to extend it, the thin pool and lv data are now all at 0%

Here is the step of what happened:

1. My thin pool metadata was full
   
2. I tried to extend them by using lvextend -L +50G and lvextend --poolmetadata +50m
   
3. I tried repairing metadata with lvconvert --repair
4. Now the thin pool as well as all its lvs show 0% data

I can't find a way to restore the pool and its lv to the working state. I really want to get some lv back. What should I try now?

Thanks!
