freebsd stable - Nov 2006 - problems with shutdown after dump on a large partition

I got problems with shutdown after dump with ?-L? (with spashots) on a 
large partition:

We have large partition with 872G on ?df ?H? report. Exactly before 
shutdown the ?dump ?Lau? was finished without any problems. After dump 
finished I run command ?shutdown ?h now? and in the result shutdown was 
incorrect because disk sync was terminated by timeout and fsck was run 
on the next boot.

I'm not entirely shure, but this looks like the snapshot generated by
"dump -L" was not yet cleaned up. You should wait a couple of minutes
(depending on the snapshot size and I/O turnover) before shutting down
the system or umounting the partition.

I don't know of a way to decide if the snapshot has been fully cleaned
up.
