Is there any method/command/utility to know what are the block numbers which
are allocated to a file in ext2 fs?

The FIBMAP ioctl gives you the block number give an integer, which is
the nth block attached to the inode. It includes blocks allocated to
store indirect blocks too.

hdparm has a FIBMAP argument iirc.  I've never used it.
