Newer versions of MacOS (OSX) have a irritating bug where mounted volumes disconnect in Finder. Sometimes, when Finder reconnects, it creates a 2nd mount with a new name like volume-1 and the original volume path doesn’t work. For applications like Crashplan that use the Unix mount volume in the path, the application fails to see the volume is mounted. To get rid of the “ghost” mount, do the following;
Mount the volume in Finder (in my case, a QNAP NAS called \\qnap\homes)
Open Terminal
$ cd /Volumes
$ ls
Macintosh HD homes homes-1 this shows the ghost volume (homes) and the active volume (homes-1)
In Finder, Eject the volume this will remove the volume-1 working volume
In Terminal
$ sudo rm -rf homes this removes the ghost volume
$ ls
Macintosh HD shows no volumes mounted
In Finder, mount the network volume
In Terminal
$ ls
Macintosh HD homes shows the Finder mounted volume is correctly named
