CIFS not working for only one volume on new OES2015

Hi,

This weekend we installed a new OES2015 server.

CIFS works fine for 2 volumes.
For only one volume it is not working..

NCP works fine.
NSS volume is mounted.

If I create a new share for that volume in iManager:
Error: Storage Error

Missing or invalid directory path for the CIFS share.

less /var/log/messages:

Dec 7 10:08:23 oesxxx CIFS[25374]: ERROR: RPC: GetVolumesList: Failed to add volume "HOME" into CIFS list, error: -1

How can this be fixed?
