Description Zdenek Kabelac 2015-10-05 11:33:16 UTC 
Description of problem:

For now lvm2 does not support fixing of metadata when VG gets inconsistent (i.e. PV is lost)

If such lost PV contained i.e. cache-pool and user caching some LV, he gets into problematic case how to get access to such cached LV back.

Unsure about best syntax -  we could go with

lvrepair

as well as with 

lvconvert --force --uncache



Version-Release number of selected component (if applicable):
2.02.131

As a 'partial' progress  lvm2 from version 2.02.175 supports  'lvconvert --repair' usage for cache & cachepool for automated usage of 'cache_repair' tool - just in-line with similar logic used for thin-pools.
