OCF_HEARTBEAT_POSTFI(7)

🌸 ocf_heartbeat_postfix(7) 🌸

okay so bestie, welcome to the OCF resource agents corner of the manual — this one's called ocf_heartbeat_postfix and it's giving mail server main character energy. Buckle up, we're learning how to make Postfix highly available, and honestly? It's lowkey iconic. 💌

---

✨ NAME ✨

ocf_heartbeat_postfix — manages a highly available Postfix mail server instance. periodt. 👑

✨ SYNOPSIS ✨

postfix [start | stop | monitor | meta-data | validate-all]

✨ DESCRIPTION ✨

So basically, this script manages Postfix as an OCF resource inside a high-availability setup. That's the whole vibe check — it's the little agent that keeps your mail server behaving in a cluster. 🦋

🎀 SUPPORTED PARAMETERS 🎀

These are the knobs you get to turn, bestie. Use them wisely:

• binary — full path to the Postfix binary. Like, for example, "/usr/sbin/postfix". (optional, string, default "/usr/sbin/postfix")
• config_dir — full path to a Postfix configuration directory. For example, "/etc/postfix". (unique, optional, string, no default — so yeah, nothing's filled in for you here 🙈)
• parameters — the Postfix daemon can be called with extra parameters, and if you've got any you just drop them right here. (optional, string, no default)

💅 SUPPORTED ACTIONS 💅

This resource agent supports these actions (a.k.a. operations). Slay:

• start — starts the resource. Suggested minimum timeout: 20s.
• stop — stops the resource. Suggested minimum timeout: 20s.
• reload — suggested minimum timeout: 20s.
• monitor — performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 60s.
• validate-all — performs a validation of the resource configuration. Suggested minimum timeout: 20s.
• meta-data — retrieves resource agent metadata (internal use only, so like... don't touch unless you know what you're doing fr fr). Suggested minimum timeout: 5s.

🌈 EXAMPLE CRM SHELL 🌈

Here's how you'd configure a postfix resource using the crm(8) shell — copy it exactly, no cap:

primitive p_postfix ocf:heartbeat:postfix \
  op monitor depth="0" timeout="20s" interval="60s"

⭐ EXAMPLE PCS ⭐

And here's the same situation using pcs(8):

pcs resource create p_postfix ocf:heartbeat:postfix \
  op monitor OCF_CHECK_LEVEL="0" timeout="20s" interval="60s"
