Setting a lifecycle policy

Step 1. Create a lifecycle policy

1. Go to the Lifecycle Policies page and click Create.

Note:
This feature is available only to a Turbo file system. If you need it, submit a ticket.
2. Specify the lifecycle policy by ‍transition period ‍or file size according to your business needs, and click Next.
Note:
You can set a file less than or equal to a value in the range of 1–64 MB as a small file.

Step 2. Apply the lifecycle policy

Apply the lifecycle policy to a path on the Turbo file system and click Submit.



Note:
You can no longer apply a policy to a directory if a policy has already been applied to its parent directory or subdirectory.
If you want to ‍apply the policy to files under /test/, you ‍can set the target path to test, /test, or /test/. The system will automatically convert them to /test/.

Viewing the storage of transitioned data

Go to the file system list page to view the storage of transitioned data.


Viewing the transitioning status of a file

To view the transitioning status of a file, use the following command:
lfs hsm_state /path/to/file
Note:
If "archived" is returned, the file has been transitioned to IA storage and has not been released from the file system.
If "released" is returned, the file has been transitioned to IA storage and has been released from the file system.
By default, a file is automatically released 1 hour after being archived. This frees up space on the file system.

Loading data

You can load files using the following commands:
For a single file:
sudo lfs hsm_restore /path/to/file
For all files in a directory:
nohup find /path/to/preload -type f -print0 | xargs -0 -n 1 sudo lfs hsm_restore &

Releasing data

After you have loaded data, you can release it using the following commands:
For a single file:
sudo lfs hsm_release /path/to/file
For all files in a directory:
nohup find /path/to/release -type f -print0 | xargs -0 -n 1 sudo lfs hsm_release &
Note:
The hsm_release operation cannot be performed on a file that has not been transitioned.
