Problems with deduplication on windows 2012 server and samba

I’m experiencing a problem with shared drives from a windows 2012 server using deduplication. The shared drives are mount to a Linux machine as:

//koffort/smidja$  /mnt/smidja  cifs iocharset=utf8,credentials=/home/andri/.smbpasswd,rw,user,dir_mode=0775,file_mode=0775,gid=1001 0 0

The Linux machine is:

> uname -a
Linux byfluga 3.12.0-rc5-4.gac42dba-desktop #1 SMP PREEMPT Wed Oct 16 10:17:14 UTC 2013 (ac42dba) x86_64 x86_64 x86_64 GNU/Linux

> cat /etc/SuSE-*
VERSION = 12.3
openSUSE 12.3 (x86_64)
VERSION = 12.3
CODENAME = Dartmouth

The problem is that some of the files are shown as links to nothing in Linux. If I check there Attributes it is set to APL so my guess it has something to do with the deduplication.

The same setup works perfectly on a Debian (Stable) machine. The only difference I can see is that there I can use the “directio” option with mount.

Ok, it’s solved for now - it needed a kernel update
