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.
