cs_wait_for_idle(8)

📦 version 3.1.3, in opensuse-leap 16.0

💅 cs_wait_for_idle — like, the manual page, but make it make sense

okay so bestie, welcome to the cs_wait_for_idle(8) glow-up ✨ this is a ClusterTools2 page, section 8, and it's genuinely one of the most useful little tools ever. no cap.

🌸 NAME 🌸

cs_wait_for_idle — literally just chills there until your HA cluster is idle. that's it. that's the whole job. main character energy of patience. 💜

✨ SYNOPSIS ✨

cs_wait_for_idle --sleep <seconds>
cs_wait_for_idle [OPTION]

okay so two ways in: either you tell it how long to --sleep, or you just hit it with [OPTION]. simple. iconic.

🦋 DESCRIPTION 🦋

cs_wait_for_idle waits until the HA cluster is idle before returning. fr fr — it does not return early, it does not guess, it just sits there doing a vibe check on your cluster until the cluster passes. 💅

🎀 OPTIONS 🎀

  • --help — shows you help. that's the whole thing. bless. 🫶
  • --version — shows the version, so you can be like "what build is this" and it will tell you. 💖
  • --sleep — sleeps for <s> seconds between probings. yes, <s>. the synopsis calls it <seconds>. same energy, same flag, don't come for me. 😭

💀 EXIT STATUS 💀

  • 0 — successful program execution. slay. ✅
  • >0 — usage, syntax or execution errors. aka something went wrong somewhere and it's telling you with a number bigger than zero. 🙈

🔥 EXAMPLES 🔥

  • Refresh HANA topology and HANA controller resources, as required before setting those resources from maintenance back to managed. Perform the actions once the cluster is idle to avoid possible problems with incorrectly detected resource status. 👑
like, this is the actual reason this tool exists. if you yank resources back to managed while the cluster is still mid-chaos, the resource status can get detected wrong and then everything is a mess. wait for idle first. periodt. 💅
# cs_wait_for_idle -s 3 && crm resource refresh
cln_SAPHanaTop_HA1_HDB00; cs_wait_for_idle -s 3 && crm resource
refresh msl_SAPHanaCon_HA1_HDB00; cs_wait_for_idle -s 3

love that for you. chain it with crm resource refresh, gate each step behind an idle check, and you're golden. 🌈

🍓 FILES 🍓

  • /usr/sbin/cs_wait_for_idle — the program itself. the whole legend. right there in /usr/sbin. 🧚
