There would be no need for xbmc to find the drive as the path to the share should already be defined by you in your xbmc.
For example on the server you connect the drive to, the drive it mounts to a directory called '/media/customvideos'. You create a share for /media/customvideos via NFS or Samba.
In xbmc you would browse to the share on the remote server and save that as a source for video content.
If the drive is not connected to the server and you try to access the share in xbmc, it will simply fail because there is no content to display.
When you connect the drive to the server, if the drive automounts to /media/customvideos, the share you created for it becomes active. So now if you try to access it via xbmc it will work. I hope that explaination helps.
Also will the Fedora server be ok if a drive that's shared over NFS is switched off?
I can't speak for Fedora, but I shouldn't think it would matter. The best way to know is to try it and see.
