We don't support online resizing yet. But you can do this offline by following these rough steps:
i) dump your metadata device to a text file using thin_dump. You may
want to eyeball this to see if it's what you expect.
ii) Create a new metadata lv. Better to create a completely new one
than try and extend the old one and risk losing data if you make a
mistake.
iii) Use thin_restore to write the dump to the new metadata volume
iv) Tell lvm to use the new metadata area for your pool. I'm not sure how to do this last step. Kabi can you help please?
