💖 FENCE_AGENT(8) — ok so, the manual, but make it make sense 💖

bestie you're reading the FENCE_AGENT(8) page from the System Manager's Manual, and today's main character is fence_virtd. Yes it's a daemon, yes it's iconic, let's go 🫶

✨ NAME ✨

fence_virtd — the fencing host for virtual machines 🦋

🎀 DESCRIPTION 🎀

okay so, fence_virtd is a host daemon whose whole job — its entire purpose, its main character arc — is routing fencing requests for virtual machines. That's it. That's the gig. 💅

fence_virt and fence_xvm talk to fence_virtd, and it supports multiple backend plugins, including:

  • libvirt for single-node operation 🌸
  • Corosync CPG and libvirt when you're using Linux-cluster release 3.0.0 or later ⭐
  • libvirt-qpid for multi-node, non-cluster operation 🦋

For compatibility, fence_xvm from linux-cluster release 2 may talk to fence_virtd. lowkey generous of it honestly 😌

fence_virtd accepts a few options on the command line, but most options are read from fence_virt.conf. so like, the command line is the appetizer and the config file is the whole meal, no cap 🍓

🌈 PARAMETERS 🌈

  • -d — specify the debug level, e.g. "-d99" 🔍 (yes, ninety-nine, go feral)
  • -c — interactively prompt the user for configuration information 🙈 (it's giving quiz time)
  • -f — specify an alternate configuration file instead of /etc/fence_virt.conf 📂
  • -F — do not fork into background after starting. this overrides any setting in fence_virt.conf 💥
  • -w — wait for the backend to be available. this also overrides any setting in fence_virt.conf ⏳
  • -p — specify the full path to the pid file used to record the active process pid 🏷️
ngl, -F and -w are the bossy ones — they walk into the config file's house and rearrange the furniture. periodt. 👑
