Hello,

I'm struggling to find information about lvmcache recovery after the cache
fails. Is it possible to access an LVcache origin if the PV for the cache
has failed?

If I try partial mode :
  lvchange -a y -P fedora/home

Then it just hangs.

If I try the home_corig directly :
  lvchange -a y -P fedora/home_corig

  "Unable to change internal LV home_corig directly"

I can see the LVs with :
   lvs -a -o +devices fedora

The home_corig is still on /dev/sdb3 so I can probably find the blocks if
needed ... but that seems like hard work!

At the moment [cache_cdata] and [cache_cmeta] are on "unknown device"
because it failed. Can I just extend to a new PV for the cache?

Thanks for any tips, and apologies if I'm being stupid.

Dan
