Defragmenting a file system
You can use the online administration utility fsadm to defragment or reorganize
file system directories and extents.
The fsadm utility defragments a file system mounted for read/write access by:
Removing unused space from directories.
Making all small files contiguous.
Consolidating free blocks for file system.
The following options are for use with the fsadm utility:
Reorganizes directories. Directory entries are reordered to place
subdirectory entries first, then all other entries in decreasing order
of time of last access. The directory is also compacted to remove free
space.
Note: If you specify -d and -e, directory reorganization is always
completed first.
-d
Use in conjunction with the -d option to consider files not accessed
within the specified number of days as aged files. Aged files are
moved to the end of the directory. The default is 14 days.
-a
Reorganizes extents. Files are reorganized to have the minimum
number of extents.
Note: If you specify -d and -e, directory reorganization is always
completed first.
-e
Produces reports on directory and extent fragmentation, respectively.
Note: If you use both -D and -E with the -d and -e options, the
fragmentation reports are produced both before and after
reorganization.
-D -E
Specifies verbose mode and reports reorganization activity.-v
Specifies the size of a file that is considered large. The default is 64
blocks.
-l
