Today I decided to rebuild my unRAID box from scratch but I want to retain all my data drives. I have wiped out my USB drive and set it up as fresh. I have my drives selected how they should be. Would I then use New Config to start the array without the drives being seen as new? I want to retain the data on all the drives. And would I use the preserve option? I just want to make sure I don't do something incorrectly here and lose the data.

Do you have a backup of your flash from before you wiped it? You will need the .key file from the config folder for your license.

 

More relevant to your question, if you have super.dat from the config folder, you can just use it and your drives will be assigned just as before with no need for New Config.

I do have back up the flash from before. So then should I just only copy over super.dat? I don't want to retain any other settings/configurations I had prior except for keeping the data on the drives. I also did copy over the key already but nothing else.

super.dat only contains your disk assignments, and whether or not the array is started/stopped. If you copied it after stopping the array (or shutting down), then it will know the array was stopped cleanly. If instead you copied it over the network while the array was running then when you boot it will think you didn't stop the array and will begin a parity check. Either way your assignments will be OK, along with your data.

Okay thanks. That seems to have mostly have done what I was hoping for, or maybe I am looking at it incorrectly.

 

After having everything up, including my cache drive, I seem to have a few folders that I am unable to get ride of. I would like to just wipe the cache drive because it seems that inside it has the following folders/files

 

\mnt\cache\system\docker\docker.img

\mnt\\cache\system\libvirt\libvirt.img

 

I tried doing an rm -r to them but when I reboot, they come back. Should they be there?

Go to the Settings page and disable both the VM manager and the Docker manager before trying to delete any of those files and folders. You will destroy any VMs and dockers you have already set up but I understand that you're trying to start afresh.

Gotcha. It was what I was looking at as well but wasn't entirely sure. Thanks again John_M and trurl for the help. I have everything running better then it was before and learned a couple of new things.
