Migrating Filesets

Directing File Placement

CLI Storage-Management Guide 14-3

Identifying the Source Fileset

The next step in configuring a placement rule is to identify the source fileset. This

chooses a set of files and/or directories based on their names, sizes, ages, or other

criteria; this set of files and/or directories changes as clients create, edit, and delete

them in the volume. The placement rule migrates all selections from the source fileset

onto the target storage, then it steers any new matching files/directories as clients

create and edit them.

You can make the placement rule select files only, directories only, or both; by

default, the rule selects files only. The default applies the fileset exclusively to

filenames. Directories are copied (or striped) only as needed to hold the placed files.

For example, the illustration below shows a small directory tree on das3 containing

two matching files. The directories that contain the matching files, /a and /a/b, are

striped to das8 so that das8 can hold those files. One file in directory /a does not

match, so it remains in the master directory on das3.
