Kris,
> A number of problems with umount are due to be fixed in 6.1 ...
Wow, ok. Thanks for the heads-up. That's honestly a little disappointing
to hear. I had hoped it was a problem with my backup script.
I posted a fuller description of this and another problem last week.
Here's the archive link:
http://lists.freebsd.org/pipermail/freebsd-questions/2006-March/114825.html
The two notes I would add to that post are:
1. The "dangling vnode" symptom did happen one other time when the box
first came online several months ago. The other sysadmin rebooted
and no further action was taken.
2. We do not have a core dump from the latest "dangling vnode" bout,
due to the system apparently hanging.
Is it likely that known umount problems explain the other symptom
("umount: unmount of /backup failed: Device busy")?
This is actually a production box, so I can't do too much testing on it.
I may be able to install the patch, though, in which case I will report
back.
Thanks again for your help!

A number of problems with umount are due to be fixed in 6.1, but are
not yet committed to the 6.x tree. Depending on how much of a problem
this is for you, you should test the candidate patch that Jeff
Roberson posted to stable@ a few days ago (check the archives). In
fact it would be very useful to know whether it fixes the issue; if it
does not we need to know ASAP if this is to be fixed in time for 6.1.
