Whenever my NFSv4 server becomes unreachable a little window pops up offering me to disconnect the affected shares.
It looks like this:
If I choose to Ignore iTunes becomes unresponsive because of the playlists that point to MP3 files located on those NFS shares that have become unreachable. I can force quit iTunes but it can never be started again. Its status becomes Not Responding, the icon jumps for a while in the dock and that's all that happens.
So, sometimes it makes sense to Ignore those stale connections to NFS shares because I know the NFS server will become available soon, but other times this ruins everything for me and I effectively cannot use iTunes until connection with the NFS server is established again. Which can "resume" an application from a freezed state immediately, btw.
My question is, can I make that little pop-up window show itself on demand somehow (run a command in Terminal, hot key, etc.) or run a terminal command to forcibly disconnect stale NFS mounts?
