Hi list,

what now worked:

- creating a cached data-lv
- creating a non-cached meta-lv
- converting data-lv to a thinpool-device with meta-lv as metadata

what not: doing the same thing with a cached meta-lv. Does this make sense?

Is the metadata already cached by lvm-logic? Do i have a cache thinpool
(with non-cached metadata) with the used way?

Tfh!
Oliver
