Re: UFS snapshot weirdness

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?


I have been experiencing these too. But it looks more like a bug in mountd, since it shows up only is snapshots are created with mount. If snapshots are created with mksnap_ffs this does not seem to show up.

I still have to make more in depth experiments, but before experimenting by myself I'd like to have some more informed directions on what to experiment.
