ibrix_tier

Manages data tiers.

Description

A tier is a group of one or more segments. Tiering enables automatic migration of files from one

tier to another within the same file system. User-written rules based on file attributes (such as

modification time, access time, file size, or file type) define the migration policy, determining which

files are to be moved and when. Tiers are defined on segments, not individual files.

Use of the tiering structure on any file system is optional. Tiering is off by default, and there is no

“default tier.”

The ibrix_tier command assigns or unassigns segments to tiers, deletes segments from tiers,

and lists information about tiers.

Use ibrix_migrator to create or delete rules defining migration policies, to start or stop tier

operations, and to list information about rules and migrator operations.
