Question

Power Cycle

Posted June 6, 2013 21.3k views
When I click on the name of my droplet, it displays several different icons, such as Power, Access, Resize, Snapshots, Backups etc. Under the Power tab, which is open by default, there is another tab Power Cycle, which, as shown below, says "This will reboot your droplet" and then it provides more info about how they recommend that it be done through the command line. Questions 1. Is this something I'm supposed to do at the beginning after creating a droplet? or is it something do during management of the server (for whatever reason if need arises) 2. Since it's recommended to do it through the command line, how do I do that? I'm using 'Ubuntu 12.10 x32 Server' ----- Power CyclePower Off This will reboot your droplet. We recommend rebooting your droplet through the command line, as this action is the same as hard resetting the server and may cause data corruption. Do you wish to proceed?

1. Power Cycle performs a hard shut down of the server, turning it off abruptly, and then starts it up again. Power Off turns the server off abruptly (in contrast to the slower Shutdown option).
2. via Telnet/SSH: "sudo reboot".

"Power Cycle" is also known as "hard reset", "hard reboot" or "cold reboot" and normally means interrupting the power supply for some seconds. This is an emergency option which should only be used if the server doesn't react to anything.

Same question - I don't want to reboot I want to shutdown. I used 'shutdown now' from the commandline which is what I've always used and I get logged out from the shell but the console says the machine goes to single user maintenance mode (or waiting to enter it) and remains active. Is that something peculiar about your standard Ubuntu 13.04 (64-bit) image? Every other machine I've used, virtual or not, really shuts down after 'shutdown'..

The same behavior applies to 'halt' (except there is no "maintenance mode" prompt).

I guess I could take it to single user and then trigger power off from the console but shouldn't I be able to do it *just* from the command line?

Or is there actually really no difference between "Power off" state and a machine that is active but halted?

@simon.waddington: I haven't seen that happening before -- are you able to reproduce it on a fresh new Ubuntu 13.04 64-bit droplet?

I'm having the same problem as LazyTiger. I have to Power Off my droplet in order for DO control panel to recognize it as Off. I created a support ticket.

Thanks to DO support, I found out that to power off the droplet from the command line I can use the "poweroff" command (also "shutdown -h now" works). The "halt" command will not actually power off the droplet.

Dear Sir,
"We recommend rebooting your droplet through the command line, as this action is the same as hard resetting the server and may cause data corruption......."

I am a new user. I created droplet with Ubuntu, and installed zPanel, my website started working now/ I want resize my server to next level. I saw one option to resize using snapshot method. But I don't want to lose my IP (even in accidently), so i want to power off the droplet and resize it in a safeway. I read in CP saw above quoted recommendation. But I couldn't see any concrete instruction for how to re-boot from command line, How to Power off etc. I can see some API Commands in Control Panel but struggling to know how to use it.

Please Help...

@cjrajeev: You can reboot a droplet by running the sudo reboot command as root.

If you want to power it off, you have to run sudo shutdown -h now or sudo poweroff.
