Re: severe hardlink bug

btrfs only fails when you have hundreds of hardlinks to the same file

use snapshots to your advantage:
 - snap source
 - rsync --inplace source to target (with some other opts that have
been discussed on list)
 - snap target
 - {rinse-and-repeat-in-24-hrs}

I understand that the case is only for *same* directory.
You can claim that it's not a standard use case, but first Michael hit that,
now me. There's at least one more case  -
https://lists.samba.org/archive/rsync/2011-December/027117.html
The count of such cases will be increasing and the sooner it will be fixed - 
the less pain it will bring to the users. I know fixing that is a big 
structural change, but it will become worse with time.
If it's not going to be fixed - I don't care. Right now I'm forced 
to migrate to old mdadm raid-1 or ZFS. The sad thing is that 
I really LOVED btrfs. Only that. ^__^
