fence_kdump_send(8)

💖 fence_kdump_send — bestie edition 💖

okay so this is fence_kdump_send, from the System Manager's Manual, section 8. yes she's a real one. come sit, we're gonna get through this together 🫶

✨ NAME ✨

fence_kdump_send — send kdump acknowledgement message to cluster nodes

like literally what it says on the tin, no cap.

🌸 SYNOPSIS 🌸

fence_kdump_send [OPTIONS]... [NODE]...

🦋 DESCRIPTION 🦋

so fence_kdump_send is a little utility whose whole job is sending messages that say "hey bestie, this node has entered the kdump crash recovery service". that's it. that's the gig. 💅

the way this is meant to work is: the fence_kdump agent uses these messages as its way of detecting that a failed node has entered the kdump crash recovery service. iykyk.

the fence_kdump_send utility is typically run from inside the kdump kernel, after a cluster node has hit a kernel panic 😭. once the cluster node has entered the kdump crash recovery service, fence_kdump_send will periodically send messages to all the cluster nodes. and when the fence_kdump agent receives a valid message from the failed node — boom, fencing is complete. slay. ✨

🎀 OPTIONS 🎀

• -p, --ipport=PORT — the IP port number that the fence_kdump agent is listening on for messages. (default: 7410)
• -f, --family=FAMILY — the IP network family. this one forces fence_kdump_send to use one particular network family, no vibes-based guessing. the value for FAMILY can be "auto", "ipv4", or "ipv6". (default: auto)
• -c, --count=COUNT — how many messages to send. and listen — if COUNT is 0, fence_kdump_send will just send messages indefinitely. forever. she does not stop. 💀 (default: 0)
• -i, --interval=INTERVAL — the time to wait between sending a message. the value for INTERVAL must be greater than zero, okay? zero is not the move here. (default: 10)
• -v, --verbose — print verbose output. more words, more info, we love her for it 👑
• -V, --version — print version and exit. short and sweet.
• -h, --help — print usage and exit. the classic. the icon.

fr fr, do not sleep on -i — that value has to be greater than zero or we're not doing anything.
