:Only rsync (via nfs) was accessing the filesystem.

:I am running HEAD from ~28h ago. Unfortunately, IIRC the machine doesn't have
:a dumpdev configured (yeah, I know). Is there any information I can get you
:via DDB?

    Try it with latest head, to make sure the bug is still there.

    I need to know whether rdist was reading HAMMER via NFS or writing to
    HAMMER via NFS, and what kinds of file structure was being copied?
    (big files, little files, hundreds of files, thousands of files.. what?).
