df -i reports '-' inodes available on reiser4

Hello,

We're evaluating reiser4 filesystem for our storage server, which will
run on linux 2.6.x.

However, according to our tests it performs very well. Becouse our
storage server will be responsible to server very *huge* amount of small
files, we need to investigate the following issue:

Command df -i reports '-' as number of used and total inodes available
on filesystem.

Is this a bug, or a feature? Or i missed out some documentation which i
should read before i formatted storage volume?


Best regards,

There is a long thread on this, which starts with a mail from Miguel on 
13.05.2004 at 09:34 (acording to my mailer). 

If you are interested in, I can send it to you by mail.

Those numbers are intentionally left to be 0.
There is a following comment in the code:

/* FIXME: Seems that various df implementations are way unhappy by such
big numbers.
   So we will leave those as zeroes.
	statfs->f_files = oids_used(super) + oids_free(super);
	statfs->f_ffree = oids_free(super);
*/

I think we should just uncomment these lines in
fs/reiser4/vfs_ops.c:reiser4_statfs().
