PowerScale OneFS 9.6.x.x CLI Administration Guide

File pool policies

File pool policies define sets of files—file pools—and where and how they are stored on your cluster. You can configure multiple file pool policies with filtering rules that identify specific file pools and the requested protection and I/O optimization settings for these file pools.

The initial installation of OneFS places all files into a single file pool, which is subject to the default file pool policy.

When you create a file pool policy, flexible filtering criteria enable you to specify time-based attributes for the dates that files were last accessed, modified, or created. You can also define relative time attributes, such as 30 days before the current date. Other filtering criteria include file type, name, size, and custom attributes. The following examples demonstrate a few ways you can configure file pool policies:

• A file pool policy to set stronger protection on a specific set of important files.
• A file pool policy to store frequently accessed files in a node pool that provides the fastest reads or read/writes.
• A file pool policy to evaluate the last time files were accessed, so that older files are stored in a node pool best suited for regulatory archival purposes.
