FilePolicy job

You can use the FilePolicy job to apply file pool policies.

The FilePolicy job supplements the SmartPools job by scanning the file system index that the File System Analytics (FSA) job uses. You can use this job if you are already using snapshots (or FSA) and file pool policies to manage data on the cluster. The FilePolicy job is an efficient way to keep inactive data away from the fastest tiers. The scan is done on the index, which does not require many locks. In this way, you can vastly reduce the number of times a file is visited before it is tiered down.

You need to keep down-tiering data in ways they already have, such as file pool policies that move data based on a fixed age. Adjust the data based on the fullness of their tiers.

To ensure that the cluster is correctly laid out and adequately protected, run the SmartPools job. You may use the SmartPools job after modifying the cluster, such as adding or removing nodes. You can also use the job for modifying the SmartPools settings (such as default protection settings), and if a node is down.

To use this feature, you must schedule the FilePolicy job daily and continue running the SmartPools job at a lower frequency. You can run the SmartPools job after events that may affect node pool membership.

You can use the following options when running the FilePolicy job:

• --directory-only: This option helps you to process directories and is done to redirect new file ingest.
• --policy-only: This option helps you to set policies. Make sure not to restripe.
• --ingest: This option helps you to is a use -directory-only and -policy-only in combination.
• --nop: This option helps you to calculate and report the work that you have done.
