LCTL-SNAPSHOT-DESTROY(8)

📦 version 2.17.58, in ubuntu stonking

💅 LCTL-SNAPSHOT_DESTROY 💅

okay bestie, gather round, because we're talking about lctl-snapshot_destroy — the Lustre configuration utility that destroys a Lustre snapshot. yes, destroys. like, gone gone. main character energy but make it demolition. 🫶

✨ SYNOPSIS ✨

lctl snapshot_destroy [-f|--force] {-F|--fsname FSNAME} [-h|--help]
                      {-n|--name SSNAME} [-r|--rsh REMOTE_SHELL]

🌸 DESCRIPTION 🌸

so the whole vibe here is: you point it at a snapshot, and it destroys it. periodt.

The tool loads the system configuration from the file /etc/ldev.conf, exactly as described in the lctl(8) SNAPSHOT section (go read that, iykyk 📖).

Then, bestie, the snapshot pieces get destroyed on every Lustre target — that's MGT/MDT/OST. all of them. no target left behind. 💀

🎀 OPTIONS 🎀

  • -f, --force — Destroy the specified snapshot by force. If the snapshot is mounted (peep snapshot_mount), it will be unmounted first and then destroyed. And even if some pieces of the snapshot are lost or broken for some reason(s) 😭, the remaining parts of the snapshot can still be destroyed when you pass this option. lowkey the "just do it" button.
  • -F, --fsname FSNAME — the filesystem name. you gotta tell her which filesystem. ✨
  • -h, --help — for help information. the classic. 🎀
  • -n, --name SSNAME — the snapshot (that's the one about to be destroyed 👀) name must be specified. not optional, bestie. required fr fr.
  • -r, --rsh REMOTE_SHELL — specify a shell to communicate with remote targets. the default value is ssh. and listen — it is the system admin's duty to guarantee that the specified REMOTE_SHELL works well among targets without password authentication. that's on you, not on the tool. 🙈

🦋 AVAILABILITY 🦋

lctl-snapshot-destroy is part of the lustre(7) filesystem package since release 2.10.0. she's been iconic for a while now. 👑

👀 SEE ALSO 👀

⚠️ heads up bestie: --force really does mean force. it'll unmount a mounted snapshot and pick up the broken pieces too. know what you're destroying before you destroy it. 💖
