Defragmenting a Volume
Defragmenting a file reassembles its pieces into the most efficient arrangement. You
can use the
snfsdefrag
command to defragment a file, a folder, or an entire volume.
To defragment a file, folder, or volume:
1
Open Terminal (in /Applications/Utilities/).
2
If you aren’t working at the SAN controller computer, use SSH to log in to the controller
remotely:
$ ssh user@computer
Replace
user
with the name of an administrator user on the controller computer and
computer
with the controller’s name or IP address.
3
Run the
snfsdefrag
command.
To defragment individual files:
$ sudo snfsdefrag -v filename [filename ... ]
To defragment a folder:
$ sudo snfsdefrag -vr folder
To defragment a volume, set
folder
to the volume name.
For more information, see the
snfsdefrag
man page or “Defragmenting a File, Folder,
or Volume (snfsdefrag)” on page 119.
