PACEMAKER(8)

💖 PACEMAKER (8) 💖

okay bestie, so you know how a cluster needs rules and somebody's gotta actually check those rules? that's this. it's PACEMAKER(8) — section 8, the System Administration Utilities corner of the manual (very grown-up, very sysadmin core), and it's part of the Pacemaker cluster resource manager.

quick heads-up before we dive in: the manpage NAME line literally says Pacemaker — Part of the Pacemaker cluster resource manager — but the tool you actually type is crm_rule. yeah. the naming is giving chaos but we move. ✨

🌸 SYNOPSIS 🌸

crm_rule <mode> [options]

that's it. that's the whole vibe. pick a mode, throw some options at it, slay.

---

🦋 DESCRIPTION 🦋

crm_rule evaluates rules from the Pacemaker configuration. literally its whole personality. you hand it a rule, it tells you what's tea. 🫖

✨ OPTIONS ✨

okay buckle up, there's a bunch, but they're all cute and organized into little friend groups. 💅

• --output-to=DEST — pick the file name for the output, or use - for stdout 🫶

okay so these are mutually exclusive — you pick one, you don't get to have two, it's not that kind of party 🙈

• -c, --check — checks whether a rule is in effect

🍓 Data:

• -X, --xml-text — use the argument for XML (or stdin if you pass -)

🧚 Additional Options:

💡 friendly reminder from the group chat: -h, --help-all, --help-output, --help-modes, --help-data and --help-additional are all there waiting for you, and the modes are mutually exclusive — don't try to run two at once, it's not the vibe.
