💖 HB_DELNODE(1) — the General commands girlies 💖

okay so bestie, we're doing hb_delnode(1) today and honestly? it's giving "breakup but make it infrastructure". sit down, get a snack 🍓, let's go.

✨ NAME ✨

hb_delnode — sends a message to a Heartbeat cluster to remove one or more nodes 💅

like. it's the girl who shows up at the group chat and says "yeah she's not coming anymore". but for servers.

🌸 SYNOPSIS 🌸

hb_delnode node [node] [node]

see how node keeps repeating? that's not a typo, that's an invitation. one node? cute. three nodes? main character energy. ✨

🦋 DESCRIPTION 🦋

/usr/share/heartbeat/hb_delnode removes a node, or multiple nodes, from the cluster configuration.

that's it. that's the job. it takes them out of the configuration. bye bye 👋

BUT. and this is the part where you need to lock in, bestie:

if there is any node in the arguments that is currently not a cluster member, the command fails and no nodes are removed.

read that again. ALL of it. if even ONE of the nodes you listed isn't currently a member of the cluster, the whole thing just… doesn't happen. nothing gets removed. zero. nada. it's all-or-nothing, no partial vibes, no "well we got most of them". it's giving "if one of us isn't invited, none of us are going" 😭 and honestly? iconic behaviour.

so vibe check your node list before you run this, fr fr.

💅 OPTIONS 💅

here's what you can pass it:

  • --help — issues a brief usage message. that's the whole list. it's a short list. a curated list. when you need a lil reminder of how this thing works, this is your girl 🫶
