volume is not unmounted after log out #152

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Fast user switching is enabled. 

Mac OS User A connects to omnium.freeman-centre.ac.uk via ssh. 

Mac OS User B connects to 139.184.225.200 via ssh. 

User B logs out. 

Issue
-----

User A finds that the volume mounted by User B is not unmounted. 

Also
----

Then in Terminal, for User A,
ls -l /Volumes 
suggests that permission is denied but in fact, I can 
cd to required volumes. I'll file a separate ticket for that issue. 

Finder access to required volumes remains OK. 

(Permission *is* properly denied to the volume that was mounted by User B.)

Before Mac OS User B logged out, 
Terminal presented the following to Mac OS User A:

-- that was, permission denied (properly) for only the volume that was mounted 
by Mac OS User B.

-- that was, permission *apparently* denied for all ssh-mounted volumes, but 
only apparent in a directory 
listing for 
/Volumes

A few minutes later, directory listing for 
/Volumes 
appears to deny permission for only one of three ssh-mounted volumes: 

[grahamperrin:~] gjp22% ls -l /Volumes/
ls: /Volumes/139.184.225.200: Permission denied

Whilst a directory listing (in Terminal) for 
/Volumes
suggests that 139.184.225.200 is not unmounted, 
Finder does not normally present a reference to that volume. 

So, this issue will probably be no problem for the 'average' Finder-focused 
user.

Restarted the computer, verbose mode.

I wondererd whether I'd glimpse something like 

> sshfs-static ... did not act upon sigterm

I didn't see that, but (if it's relevant) I did glimpse something like

> daemondo ... did not act on sigterm

It is not in the file system's scope to mount/unmount volumes itself, 
create/delete mount points, etc. Something 
else, such as the Finder, or a GUI that knows how to interact with MacFUSE, 
should be handling these things. It is 
possible to have hooks for login, logout, shutdown, sleep, wakeup etc., so the 
higher layer software can try to do 
the right thing based on what's happening.

Looks like the permissions behavior you are seeing is explained by my reply to 
your other permissions-related 
issue report, right?
