When we came in this morning, our server has lost it's NFS connections to the Open-e server. On our server, the command df -h showed the nfs mounts, but the stats were all blank. I was unable to view the contents of the mounted directories, and I was unable to unmount them, I received an error, about the share being in use. I ended up rebooting both the Open-e server and my server in order to get the NFS shares mounted again.

Over the weekend I tried to run a backup, on the open-e server. The backup appears to have failed, could this have caused my server to lose it's connection to the NFS shares?

Where in the open-e logs should I look to try to figure out what happened?

Any help would be appreciated,
Thanks
