Querying file system fragmentation

To query the status of the amount of fragmentation for a file system, specify the file system name along with the -i option on the mmdefragfs command.

For example, to display the current fragmentation information for file system fs0, enter:
mmdefragfs fs0 -i
The system displays information similar to:
"fs0"    10304 inodes:    457 allocated / 9847 free
