no, Samba doesn't cache created files or directories. Older versions had 
a write cache that could optionally cache recent writes to a file, until 
the file handle got closed by the client, but this cache has been 
removed quite some time ago.

So I guess what happened is that all the stuff that got added by the 
clients was lost due to the filesystem corruption on the server.
