ZPOOL-DDTPRUNE 💅

okay bestie, welcome to zpool-ddtprune, section 8 of the System Manager's Manual — yes she lives in the same house as all your other zpool girlies 🫶

✨ NAME ✨

zpool-ddtprune</purl> — Prunes the oldest entries from the single reference dedup table(s) 🧹🦋

✨ SYNOPSIS ✨

zpool ddtprune -d days | -p percentage pool

✨ DESCRIPTION ✨

so this command prunes older unique entries from the dedup table. literally, it goes in and clears out the old stuff so the table can breathe 💖

think of it as the complement to the dedup quota feature — like, quota is one half of the outfit and ddtprune is the other half. it lets you remove older non-duplicate entries so there's room for the newer duplicate entries to move in. it's giving "making space for the new main characters" ✨

and how much does she prune? two ways, pick your vibe:

  • by a target percentage of the unique entries (that's the -p percentage route), or
  • by age — meaning every unique entry older than N days gets the boot (that's -d days) 👑
