A computing device includes an interface, memory, and a processing module. The memory stores a directory and inode tables. The directory stores a file identifier and a corresponding inumber for each file that is stored in storage units. An inode table stores an inumber, metadata, and a DSN address for each file stored in a corresponding storage unit. The processing module is operable to monitor, for each of the inode tables, utilization of the memory. The processing module is further operable to monitor, for each of the storage units, utilization of memory of the storage units. The processing module is further operable to process, for the inode table and/or the corresponding storage unit, per inode table memory utilization data and per storage unit memory utilization data to adjust memory utilization of the inode table and/or memory utilization of the corresponding storage unit.
