Creating volumes from the CLI

[HeloJunkie]

I am attempting to create volumes from the command line and I am not having any success. I suspect I am missing something simple but I cannot figure it out. Creating them from the GUI works fantastic, but I want to learn to do everything from the command line.

Looking at the docs shows me that I am using the correct command(s) but still no luck. Any guidance would be helpful.

Running 9.2.1.8

Thanks

Do yourself a favour and forget about FreeNAS because it is embedded system and makes things much harder. Get a copy of TrueOS. Install on the same system and read

In Freenas lots of things are not supposed to be done from CLI if you want the system to behave properly...and creating a volume is one of that....

You seem rather intent on drawing people away from FreeNAS for no real reason.

The answer is that you don't use the CLI. Using it will screw up the back end that keeps FreeNAS running coherently. You must use the GUI whenever possible.
There is an API, but few around here have experience with it.

Why do you think that? Just because I answered three threads in a raw where FreeNAS was not the right tool for the job.

It seems that we at least agree that using CLI is in most cases wrong thing to do with FreeNAS. Now he stated explicitly that he wants to learn how to use CLI. Thus my advise which you didn't like. Now check two other threads and see if my advises were not reasonable.

FreeNAS has been downloaded close to 6.5 million times. If you think that my comments can shrink its user base you have to drop that keyboard for couple of days and go for a long walk in the forest.

I'm pretty sure you are still in test mode and learning. So no reason not to learn the ZFS CLI. FreeNAS can get out of sync with GUI and the actual system if you do things behind its back. It also expects to see two partitions, one swap, one data mapped to gptid... so manual creation is a general no-no. But if you dig, one of the devs wrote a nice little walkthrough and I think we may even have a section in the manual ( sorry not looking right now. ) You can sync your pool to the GUI with an export, and auto import. But for production you are much better off giving FN EXACTLY what it expects to see. So creation via GUI is best.

Interestingly your command syntax is correct. So there must have been something else going on. Maybe something exists already as vol1? Not sure. Just for fun I threw a log of messing around with those commands so you can see for your self. Only 3 disks so sorry this log was just a stripe, the z1 pool I just did on the shell to test both for ya. This is a disposable 9.3 beta testing box.

So not sure what's up. Something was up with your sys, clear the pools in the gui reboot and try again? Or just play more. Lots of us use the CLI where it is safe, just steer clear of things that might confuse FN. It's pretty trivial to create a jail and have a full freebsd install at your disposal with no chance of screwing the main sys up. Good luck.
