A method begins by a processing module determining an imbalance between inode utilization and data storage utilization. When the imbalance compares unfavorably to an imbalance threshold, the method continues with the processing module determining whether utilization of another inode memory and utilization of another corresponding data storage memory are not imbalanced. When the utilization of the other inode memory and the utilization of the other corresponding data storage memory are not imbalanced, determining whether the inode utilization is out of balance with respect to the data storage utilization. When the inode utilization is out of balance, the method continues with the processing module transferring data objects from a data storage memory to the other corresponding data storage memory and transferring mapping information of data objects from a inode memory to the other inode memory.
