- the OS X finder shows: “Connection Failed”
- one of the filesystems (“home”) was mounted beforehand
- it seems impossible to remove that dangling mount point
- all three of my DiskStations seem equally concerned: DS213+, DS112+, DS115j
- I need to reboot the Mac in order to be able to mount any of the filesystems of the concerned DiskStation again – I hate rebooting and losing desktop and application state
Update 2016-01-10:
With cmd-K (“Connect to Server…“) it works rather smoothely – but still not perfectly.
