102 Chapter 3 Managing SAN Storage
Defragmenting a Volume
Defragmenting a file reassembles its pieces into the most efficient arrangement. You
can use the snfsdefrag command to defragment a single file, a folder (directory of
files), or an entire volume.
To defragment a file, folder, or volume:
1 Open Terminal (in /Applications/Utilities/).
2 If you are not working at the SAN controller computer, use SSH to log in to the
controller remotely:
$ ssh user@computer
where user is an administrator user on the controller computer and computer is the
controller’s name or IP address.
3 Run the snfsdefrag command (in /Library/Filesystems/Xsan/bin/).
To defragment one or more individual files:
$ sudo snfsdefrag filename [filename ... ]
To defragment an entire folder:
$ sudo snfsdefrag -r folder
To defragment an entire volume, set folder to the root directory of the volume.
For more information see the snfsdefrag man page or “Defragmenting a File, Folder,
or Volume (snfsdefrag)” on page 177.
