I read somewhere else about NFS issues on 7-RC* where snapshots have  
been used. In particular - and this is something I'm seeing too -  
changing the exports file or reloading mountd gives the following in  
messages log:

Feb 19 18:58:09 anduin mountd[38867]: can't delete exports for /tmp:  
Invalid argument
Feb 19 18:58:09 anduin mountd[38867]: can't delete exports for /usr:  
Cross-device link
Feb 19 18:58:09 anduin mountd[38867]: can't delete exports for /var:  
Cross-device link
Feb 19 18:58:09 anduin mountd[38867]: can't delete exports for /export/ 
home: Cross-device link
Feb 19 18:58:09 anduin mountd[38867]: can't delete exports for /opt:  
Cross-device link

Can this be related? I'm starting to worry here - what will be the  
long-term consequences if snapshots are stuck around in this  
"invisible" state?
