Running amcheck during amdump

[Toomas Aas]

I'm thinking about setting up an 'amcheck -m' run for early morning.  
This is a remote site doing backups to external USB hard disk, and  
they tend to forget to replace the disk once a week, so I'd like to  
have the "FIX BEFORE RUN IF POSSIBLE" e-mail waiting for them first  
thing in the morning. However, in case the disk has actually been  
repaced on time, the early morning amcheck run might coincide with  
amdump in progress. Can this have any bad effects?
