Profile Synchronisation Issues

A new issue has cropped up in our environment that sees a Users folder having its core folders names changed during a profile synchronisation that occurs when a user logs in or logs out.

 

Essentially everything is renamed with a -network suffix. So Documents becomes Documents-network, Desktop becomes Desktop-network etc and aliases for the redirection are also created. This seems to result in that the next time they login they cannot see network shares that are usually on the Desktop including the Dropbox.

 

Given the restrictions on the accounts the students cannot rename their folders (have verified this myself), and to return them to normal I have had to rename the folders via sudo terminal commands so I think I can safely dismiss user action as the culprit.

 

The Macs are wired up via Ethernet and Airport is disabled, additionally they are set so that they do not sleep so network connection should be consistent. All clients are on Snow Leopard 10.6.8.

 

The oddity about it is the seemingly random nature in which it occurs, it is not always the same person or same Mac which is why I suspect theres an area of fault in the synchronisation process.

 

We have had this setup for nearly 2 years without this problem occurring, it has only cropped up in the past few weeks.

 

For now I appear to be able to manage the problem since our Mac numbers are relatively low however I cannot continue to treat the symptom and need help in flushing out the cause of the problem.

    Hi CL --

     

    The reason you are getting -network behind the names is due to a sync conflict.  i.e. Workstation file is older than the server or vice versus.  Probably at one point in time, a selection was made to keep both files on a conflict (click happy people/kids) can do this -- and one of the settings is to make it the default.

     

    I forget where you change this option.  One thing that you can do to reset the sync -- is to remove ~/Library/FileSync folder as well as the hidden file .FileSync that is located in the root of the user's home folder.  I also push permissions back through the  folder as well.  I think jumping from machine to machine can sometimes corrupt permissions (depending on the state of the workstation last used).

     

    You can delete the -network files -- however, if they have stickies or a bookmark file, I'd keep both.  It is likely that the desired file is actually in the -network file.  The other one, is an empty and fresh file.

     

    You might also use sudo du -hs ./* on the root of the users directory -- this will tell you the file sizes of the home folders.  The bigger the home folder, the more likelyhood of having sync errors.

     

    Hope some of this info helps you --Hoosierchick

    To add to what hoosierchick2012 said I've also seen this behavior ( creation of -network files) when users get impatient waiting for sync to finish and cancel the sync

    Another cause can be incorrect time on client machimes

    This can happen with laptops when users let the battery go flat

     

    Another problem can be iPhoto library,  syncing it

    can cause issues mainly because the OS sees it as one giant file

    Users only have to open it and that's enough to cause a complete re sync

    Not so much of a problem if users only have a small  amount of photos

    Potentially a big problem when users have a lot of photos
