I want to play around a bit more before production, is this okay?

TrueNAS General
1

Have TrueNAS installed in my 4 bay NAS with 2 drives in a mirror.

Can I:

  1. back up config file to my computer

  2. shut down

  3. remove the 2x drives

  4. reinstall truenas

  5. use spare/random drives

  6. play around more with settings, versions, test some stuff, etc.

And then…

  1. shut down

  2. remove placeholder drives

  3. reinstall truenas

  4. insert my “production” drives

  5. reload the config file

… and all is good? Or have I missed something important/is there still a risk?

The data already exists in another place as a backup, but I would absolutely be annoyed having to recopy the data back to the drives to “start fresh” again.

Short answer: Yes. TrueNAS is designed to do exactly this. As long as you have the config file, you can blow away the entire boot drive, install new, and load the config.

It should automatically detect and import the pools that were active at the time of saving the config.

Long answer:

Yes.

Thanks for the long and short answers!

never done it so just really wanted to make sure I wasn’t totally crazy, or totally fine but missing a critical step… :+1:t2:
