You can reorganize or compact a fragmented file system using fsadm, even while the file system is mounted. This may help shrink a file system that could not previously be decreased.
Note:
If a file system is full or busy, the reorg operation may fail.
To reorganize a VxFS file system
Use the fsadm command to reorganize a VxFS file system:
Reorders
directory entries to put subdirectory entries first, then all other entries
in decreasing order of time of last access. Also compacts directories to remove
free space.
-D
Reports
on directory fragmentation.
-e
Minimizes
file system fragmentation. Files are reorganized to have the minimum number
of extents.
-E
Reports
on extent fragmentation.
mount_point
The file system's mount point.
-r rawdev
Specifies the path name of the raw
device if there is no entry in /etc/fstab and fsadm
cannot determine the raw device.
