Please give the patch set btrfs: extended inode refs by Mark Fasheh a try
(http://lwn.net/Articles/498226/). It eliminates the hard links per directory

Hi, Jan!

I'd suggest that using btrfs for production servers is probably a bit

Hello,
I was running btrfs fi balance start -dusage=5 -musage=5 -v / on 3.5.0, and
soon these BUG happened. Then some fs syscalls started to block (in mutt, find,
...), and after a while the computer (remote) stopped responding by ssh. After
rebooting, the balance continued fine.

Currently btrfs has a limitation on the maximum number of hard links an
inode can have. Specifically, links are stored in an array of ref
items:
struct btrfs_inode_ref {
__le64 index;
__le16 name_len;
/* name goes here */
} __attribute__ ((__packed__));
The ref arrays are
This patch adds basic support for extended inode refs. This includes support
for link and unlink of the refs, which basically gets us support for rename
as well.
Inode creation does not need changing - extended refs are only added after
the ref array is full.

The iterate_irefs in backref.c is used to build path components from inode
refs. This patch adds code to iterate extended refs as well.
I had modify the callback function signature to abstract out some of the
differences between ref structures. iref_to_path() also needed similar
changes.
Teach tree-log.c about extended inode refs. In particular, we have to adjust
the behavior of inode ref replay as well as log tree recovery to account for
the existence of extended refs.
