Reorganizing a file system

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:

      fsadm [-t vxfs] [-e] [-d] [-E] [-D] [-r rawdev] mount_point

vxfs

The file system type.

-d

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.
