Can't Mounting Disk-on-module


When i want to mount the DiskOnModule on QNX 6.3 a receive this error :

mount /dev/hd1t79 /mnt/DOM

mount : Can’t mount /mnt/DOM (Type QNX4)
mount : Possible Reason : Resource Busy

Please help me

perhaps /dev/hd1t79 is mountet allready to some other mount-point (e.g. /fs/hd1-qnx)

check the output of df to see the partitions and the mountpoints.
