zpool-ddtprune8

Prunes the oldest entries from the single reference dedup table(s)

Usage

zpool {ddtprune -d days | -p percentage pool}

Overview

This command prunes older unique entries from the dedup table. As a complement to the dedup quota feature, ddtprune allows removal of older non-duplicate entries to make room for newer duplicate entries.

The amount to prune can be based on a target percentage of the unique entries or based on the age (i.e., every unique entry older than N days).
