Me and my colleague was troubleshooting a broken cluster today… apparently the new continous file share in Windows Server 2012 does not like the old 8.3 file name format. You can use fsutil to clean this up:

fsutil 8dot3name query x: – Find out what the problem is

fsutil 8dot3name set – Change the settings

fsutil 8dot3name strip x: – Strip the old named

Verify that you do this on all the nodes
