> We keep persistent cache meta on node, which is filtered by the cache node filter. If such cache is removed, some nodes can retain 'cache_data.dat'. 
> Such nodes can't re-join cluster because they find this 'cache_data.dat' and offer the cache when joining the cluster. But the cache has been removed: 
> {code:java}
> org.apache.ignite.spi.IgniteSpiException: Joining node has caches with data which are not presented on cluster, it could mean that they were already destroyed, to add the node to cluster - remove directories with the caches[TestDynamicCache]
> {code}
> This happens because we remove persistent cache data in `GridCacheProcessor#prepareCacheStop` looking at `Map<String, GridCacheAdapter<?, ?>> GridCacheProcessor#caches`. But there is no GridCacheAdapter for the cache if the node filter excludes this cache for the current node. But 'cache_data.dat' exists. 
> The work-around is to acquire a cache proxy on the node for which this cache is excluded:
> {code:java}
> // This fixes the issue!
> // cache = grid(2).cache(cfg.getName());
> {code}
> This creates the proxy and registers missing GridCacheAdapter.
