Start jail from command line

[flanello]

How can a jail be started and stopped form the command line?


The following doesn't work:

Code:

service jail start <Jail_Name>
service jail stop <Jail_Name>

[pre]
warden start <Jail_Name>
warden stop <Jail_Name>[/pre]

Be careful with even considering this.. you're doing it behind the back of the WebGUI, and it can get upset and do nasty things...

I'm intrigued, what nasty things could happen?

Not a developer so I'm not sure. But, 99% of what people do from the CLI, if it's anymore more than looking at things(ie checking SMART status, time check, permissions, etc.) it's something that can go badly without warning. Generally, if the manual doesn't tell you to do it you probably shouldn't. The WebGUI does things and expect nothing to be done behind it's back. If you start doing things behind it's back it'll get upset. It's caused tons of problems for people.

When give a choice between FreeNAS trashing your jail(s) and just not doing this from the CLI, guess what the conservative choice is? ;)

This is partly why the FreeNAS API was created. Too many people wanted to do things behind the WebGUI's back and it ended badly. We've had lost pools from bad CLI choices before. You should be using the WebGUI or the API ONLY unless you are 100% sure what you are doing is safe. Even innocuous things have proven fatal to configurations in the past. So don't be fooled because it seems pretty minor to do something from the CLI.

Or, if you like experimenting, setup a VM and play with that!

Thanks for the information.
Using the API seems to be a good idea, although it could be a bit difficult using it the first time.

I'm necroing this thread for the future reference of others, here's how you can do this through the API from the command line:

Code:

curl -v -u username:password -X POST http://localhost/api/v1.0/jails/jails/<jailid>/start/

Replace username : password with your freenas root username/password. Replace <jailid> with the jail number.
I don't have many jails, so I just tried a few different ones until I got the right one. I'm sure there's a better way to find it, though (maybe "jls" command on the command line will show it).

Stop is /stop/ instead of /start/. I didn't try stop though, as I have no need for it.

Thank you for the tip

Code:

sudo warden list -v | egrep "(id:|host:)" # to get the jailid's

jls will work too
