Mount of NFS-Shares unpossible

Hello,

due to a hardware problem our NFS Server crashed. Due to this crash we installed the NFS server on new hardware. We attached the the physical NFS drives to the new server - the drives are working well and all files / directorys are locally accessible.

The NFS Export shares on RHEV-M can not be mounted/activated/... and can not be detached. We are using RHEV 3.1

Is there a way to re-import already registered NFS-Export shares?

Best regards, Stefan Marleaux
