Hi, As described at [1], btrfs limits (to less than 200 or so) on the number of hard links to a single inode in a given directory. This is due to a flaw in the on-disk format. This hurts busybox-style programs like git that want to keep many links to a single binary and backup programs like backuppc. 3.7-rc1 is said to fix this[2], provided users set an appropriate on-disk flag to accept the format bump. Ideally I'd like to see these patches in wheezy so that wheezy could read such filesystems once they become more widespread. b916a59adfdc Btrfs: add missing read locks in backref.c 5a1d7843ca4b btrfs: improved readablity for add_inode_ref f186373fef00 btrfs: extended inode refs d24bec3ae528 btrfs: extended inode ref iteration Untested. Patches attached for reference. Any heroes to try these with xfstests and then in everyday use? Until they get more testing, perhaps they can provide some amusement.
