sanlk-reset — host reset program
sanlk-reset [Options] action lockspace_name ...
The sanlk-reset program sets events in specified sanlock lockspaces. Events are defined to cause sanlk-resetd on another host to:
- use wdmd/watchdog to reset the host
- use /proc/sysrq-trigger to reboot the host
Both hosts must be operational and have continued access to a common lockspace for the reset request to succeed. After setting the event, the sanlk-reset program monitors the host status in the sanlock lockspace until the target host is dead.
The sanlk-reset program can also be run on the same host as sanlk-resetd to update which lockspaces the local sanlk-resetd is watching for events.
- --version, -V
- --help, -h
Reset another host
The event is set in each lockspace specified. The target host may have a different host id in each lockspace.
sanlk-reset reset lockspace_name:host_id ...
- --host-id, -i num
Host id to reset. (Use only with single lockspace name.)
- --generation, -g num
Generation of host. (Use only with single lockspace name.)
- --sysrq-reboot, -b 0|1
Enable/Disable (1/0) use of /proc/sysrq-trigger to reboot.
- --resource-mode, -R 0|1
Resource leases are used (1) or not used (0) to protect storage.
- --native-timeout, -t num
Disable native timeout by setting to 0.
