How does the storage pool REUSEDELAY parameter affect data extents in a container storage pool?

By specifying how long data extents, that are no longer referenced, canbe eligible for reuse before they are removed from the storage system. The data deduplication process for directory-container and cloud-container storage pools identifies the last date and time that the data extent was referenced to determine whether the data extent can be used again. If the data extent is already used by another object, or if the data extent is within the reuse delay period, the data extent is reused if the data deduplication process matches the data extent. The REUSEDELAY parameter is setin days, and can be increased if longer reuse periods are required. Longer reuse periods mean that the data in the storage pool is retained longer before it is deleted due to lack of use.
