Emergency Reboot (when shutdown does not work)

[tcharron]

The following commands can be used to simulate physically pressing the reset button on your server.

Thi should work remotely even when reboot or shutdown commands don't.

 

echo s > /proc/sysrq-trigger
echo 1 > /proc/sys/kernel/sysrq 
echo b > /proc/sysrq-trigger

 

The first command tries to sync discs.  The second activates linux magic commands, and the third requests a reboot.

 

This should be considered a last resort -- expect a parity sync when the reboot happens.
