I am seeing a strange behaviour sometimes when mounting afp network
volumes on an Intel iMac.
The problem isn't caused by you mounting them; it's an interaction
between
unmounting them and an application bug.
Essentially the OS is creating more than one /Volumes representation
for the drive, depending on what steps have occurred, and its
creating a persistent entry in /Volumes which I can't 'unmount'
The OS didn't create it, and you can't "unmount" it because it's a
directory (folder).
For example:
I have another Mac sharing its hard disc. This volume is called
"G4_HD". When I try to mount it on the iMac, it ends up being
referred to as G4_HD-1 by Unix (in /Volumes). This is because
there is already a 'persistent' entry in /Volumes called 'G4_HD' from
some earlier life. This persistent entry only contains one of the
directories which belong to the volume.
The fact that it contains another directory is a giveaway; what has
happened is that the volume has been unmounted at the same time
that an application has decided that it is going to create (e.g.)
/Volumes/G4_HD/SomeFolder/SomeDocument and the application has
stupidly assumed that it should create *any* intervening directories
(it may even have asked the user) along the way.
As the volume was unmounted, /Volumes/G4_HD ceased to exist, and
so the application created it again.
The problem I have is that I am using
file:///Volumes/Drive/Folder/File style URLs to pass pointers to
files over a network connection. When I use CFURL to resolve a URL
like:
file:///Volumes/G4_HD/folder/file
As you can see, this is an inherently fragile way to do things. Even
without
the bug discussed above, I can't recommend this as a way to go.
So, I have 2 questions:
1) What is this phantom directory ?
It's a directory.
2) How do I solve my problem and avoid this in the field ?
a) delete it
b) find and either fix or avoid the application that created it
