ocfs2's bmap output
...ckable file system and one of it's features is that it
can combine many sparse files into a single view. On ext2/3 I was using
bmap to give me the information needed, so for instance, if I created a

get something like
blade12:~# ~/a.out abc
File: abc Size: 30002 Blocks: 8 Blocksize: 4096
