SANLK-RESETD(8)

✨ SANLK-RESETD ✨

okay bestie, welcome to the sanlk-resetd page — that's the host reset daemon from the System Manager's Manual, and she is not here to play. this one's got range: it watches lockspaces, and when something goes sideways it nukes the host. no cap. 💅

🌸 SYNOPSIS 🌸

sanlk-resetd [OPTIONS] lockspace_name ...

🦋 DESCRIPTION 🦋

so like, the sanlk-resetd daemon ✨gets events✨ from the sanlock lockspaces you name. and when those events show up, they're defined to make sanlk-resetd do one of these two things:

• use wdmd/watchdog to reset the host 💀
• use /proc/sysrq-trigger to reboot the host 🔥

okay so now the fun part. the sanlk-reset program can be run on another host, and it can request that sanlk-resetd reset the host it's running on. it's giving long-distance chaos. for that reset request to actually succeed, both hosts must be operational and both need to have continued access to a common lockspace — no shared lockspace, no reset, periodt. after setting the event, the sanlk-reset program monitors the host status in the sanlock lockspace until the target host is dead. yes, dead-dead. 🪦

but wait, there's more 💖 the sanlk-reset program can also be run on the same host as sanlk-resetd, and in that case it updates which lockspaces the local sanlk-resetd is watching for events. so it's like, a little settings refresh for your local daemon. iconic.

🎀 OPTIONS 🎀

• --version, -V — print the version. that's it, that's the whole thing 🫶
• --help, -h — print usage. your girl when you forget how she works 💅
• --foreground, -f — don't fork. stay right here in front of you, main character energy ✨
• --daemon-debug, -D — enable debugging to stderr and don't fork. two-for-one, we love a multitasker 🔥
• --sysrq-reboot, -b 0|1 — enable/disable (1/0) the use of /proc/sysrq-trigger to reboot. flip the 1 to turn it on, 0 to turn it off 🌈
• --sysrq-delay, -d sec — delay this many seconds before using /proc/sysrq-trigger. a lil dramatic pause before the drop 😭
• --resource-mode, -R 0|1 — resource leases are used (1) or not used (0) to protect storage. pick your vibe: 1 = leases on, 0 = leases off 💜

heads up bestie: 0|1 means exactly those two values, and sec is a number of seconds. don't get creative, the daemon will not be charmed by your creativity 🙈
