On HP-UX the tool 'tusc' (trace unix system call) is the equivalent
tool to 'strace'.  Using it you should be able to see the underlying
system calls and their status returns.  That would provide a valuable
clue as to where the problem lies.

You are using a combination of operating system and filesystem that
isn't very commonly seen.  Nor is it available to the developers
here.  You may very well have found a bug.  But is the bug in
coreutils mv or in the filesystem or in the kernel?  Any of those are
almost equally likely possibilites.  And not having such a system to
try it means that we will need to rely upon you to help.
