🌸 NAME 🌸

ocf_heartbeat_fio — fio IO load generator 🦋

---

💅 SYNOPSIS 💅

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

---

🫶 DESCRIPTION 🫶

so like, fio is a generic I/O load generator, no cap. 💫

this RA lets you start and stop fio instances so you can simulate load on a cluster without having to configure a whole pile of complex services. it's giving "chaos, but make it tidy." 🔥 the way that you just spin up load and dip? iconic. 👑

---

✨ SUPPORTED PARAMETERS ✨

one parameter, one queen, let's go 🎀

• args — arguments to the fio client. minimally, this should be a (list of) job descriptions to run. 💖

this one is optional, it's a string, and there's no default — so if you don't pass it, you don't pass it. 🤷♀️

👑 SUPPORTED ACTIONS 👑

this resource agent supports the following actions (operations), and yes every single one matters, don't skip a single one bestie:

• start — starts the resource. suggested minimum timeout: 60s. ⏱️
• stop — stops the resource. suggested minimum timeout: 60s. 🛑
• monitor — performs a detailed status check. suggested minimum timeout: 60s. suggested interval: 10s. 👀

🌈 EXAMPLE CRM SHELL 🌈

here's an example config for a fio resource using the crm(8) shell, and I'm giving it to you exactly, character for character, because we do not play with commands around here:

primitive p_fio ocf:heartbeat:fio \
  op monitor timeout="60s" interval="10s"

slay. copy it, love it, live it. 💜

🦋 EXAMPLE PCS 🦋

and here's the same energy but for pcs(8):

pcs resource create p_fio ocf:heartbeat:fio \
  op monitor timeout="60s" interval="10s"
