Hi

Sorry but version 133 is really ancient - the original purpose of 'cache' 
--splitcache was rather more debug oriented.

Clearing of cache-pool metadata when cache-pool is reattached to another LV 
goes with version 2.02.162 - so your version is way too old...

In your case - just destroy the cache (--uncache) and do not try to reuse 
cache-pool unless you really know what you are doing.
