This is a good thought-provoking idea. The main purpose of this Samba NAS is 
for Mondo backups, so the 'df' that I run now just before each ISO is 
written should do the trick, but doesn't always for some reason. A general 
'df' every 10 minutes or so in crontab would cause the log errors to go away 
also. I was hoping for a more technical solution, but the simple, obvious 
stuff is usually better as to 'fixing' things. I'm thinking of using this 
for Bacula also, and the cron job would probably take care of that also.

Thanks so much.
