NAME
zpool-ddtprune – Prunes the oldest entries from the single reference dedup table(s)
SYNOPSIS
zpool ddtprune -d days | -p percentage pool
DESCRIPTION
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).
