Hello
How do I list Reiser4 Statistics on number of files on r4 partition and
disk space used and space saved with compression ?
I can list these items at this time [1]
Thanks Glenn

I don't know how to do it offline. Perhaps there are
proper tools (measurefs, or so) in reiser4progs.

sync(1) + df(1) will show occupied space.
Also you can use du(1) utility. However,
you must fsck your partition with --fix option before
using du (i_blocks and i_bytes are unsupported online
because of performance issues).

So, du(1) is to monitor compressed size, ls(1) - non-compressed one.
That said, you can calculate compression ratio for every reiser4
file(directory).
