LCTL-NODEMAP-FILESET-DEL(8)

💖 lctl-nodemap_fileset_del — the "okay we're DONE with that fileset" button 💖

Bestie. Come sit. Today we're learning lctl-nodemap_fileset_del, an 8th-section Lustre Configuration Utilities baddie whose whole personality is deleting things. Iconic behavior, honestly. ✨

---

🌸 NAME 🌸

lctl-nodemap_fileset_del — delete filesets from a nodemap. That's it, that's the whole job, and she does it flawlessly. 💅

---

🎀 SYNOPSIS 🎀

Two ways to summon her, pick your fighter:

lctl nodemap_fileset_del

or

lctl nodemap fileset_del --name NODEMAP_NAME [--all] [--fileset
                         SUBDIRECTORY]

---

🦋 DESCRIPTION 🦋

Okay so here's the tea. nodemap_fileset_del deletes all filesets, or just one specific fileset by its SUBDIRECTORY path, from a nodemap — and you tell it which nodemap by handing over its NODEMAP_NAME. 🫶

And what even is a SUBDIRECTORY? It's a relative path from the root of the Lustre file system. Not absolute, bestie — relative. Note it. 📝

Also lowkey important: this operation can delete both primary and alternate filesets. Both. So yeah, she's thorough. Main character energy with zero hesitation. 😭

---

✨ OPTIONS ✨

• -n, --name _NODEMAP_NAME`_ — The name of the nodemap that one fileset, or all of the filesets, should be deleted from.
• -f, --fileset _SUBDIRECTORY`_ — The specific fileset to be deleted, identified by its path.
• --all — Tells it that all filesets should be deleted for the given nodemap. Alternatively, --fileset '*' does the exact same thing if that's more your vibe. Heads up though: this option is mutually exclusive with --fileset — so pick one, don't be messy. 🙈

---

🌈 EXAMPLES 🌈

Deleting two different filesets from two different nodemaps — look at her go:

# lctl nodemap_fileset_del --name tenant1 --fileset '/dir1'
# lctl nodemap_fileset_del --name tenant2 --fileset '/dir2'

And now the nuclear (but polite) option — deleting all filesets from a given nodemap, demonstrated both ways because we love options:

# lctl nodemap_fileset_del --name tenant1 --all
# lctl nodemap_fileset_del --name tenant2 --fileset '*'

Same result, two flavors. Chef's kiss. 👑
