New submission from Ralf Schmitt <ralf@systemexit.de>:
I'm trying to use dragonflybsd as a backup server. I'm rsyncing from
multiple remote systems to a dragonfly master. Running ls -la in one
of the synced directories in a snapshot gives me "No such file or
directory errors":

The missing files are all hard links to the same file, I guess they
haven't changed during backups.
dmesg contains missing inode warnings:
