Migrating Filesets

Directing File Placement

14-6 CLI Storage-Management Guide

This configuration mainly focuses on new directories and their sub-trees. The

placement rule steers new directories to das8. Since the new directories are created on

das8, the das8 instance of the directory is master. By default, all of its child files and

directories follow it onto das8. Directory /a/b/c therefore grows on das8, as would any

other new directories in the volume. Files are not matched by this rule, so they always

go to the filer that holds their parent’s master directory; the old directories (/a and

/a/b) therefore store all new files on das3, and files in the new directories go to das8.

This configuration is designed to move all of the major tree growth onto the target

filer.

In the

from fileset command, you can use the match directories argument to choose

directories only. This causes the placement illustrated above:

from fileset fileset-name match directories

where

fileset-name (1-64 characters) identifies the source fileset, and

match directories applies the fileset only to directories, not files.

For example, the following command set makes an all-inclusive fileset and uses it to

match all directories:

/acct

/a/b

/a/b/c
