The filefrag utility provides most of this info. I have submitted
a patch that teaches it about shared too.

# filefrag -v Random
Filesystem type is: 7461636f
File size of Random is 409600000 (100000 blocks, blocksize 4096)
 ext logical physical expected length flags

Random: 5 extents found

attr(1) should suffice for xattr.
