Q: I want to set up a FreeNAS server for data storage. I have small hard drive that is 40 GB and 2 other hard drives that are 320 GB each. I want my data to be on those 2 hard drives and I want to make them mirrored drives so if one fails the other one stay alive.

Do I do mirror after the installation from the GUI after the install and is there an option? If not what’s the best way to proceed?

Q: If I upgrade my FreeNAS server will I lose my data on my disks? I don’t have time to try that on VM so just wondering if you guys have done that?

Q: When I try to make a  web server on FreeNAS, I get this message “Error: The changes could not be applied (error code 1).” How do I fix this?

Q: I am trying to enable FTP service on my FreeNAS server. When I do save & restart I get an error message saying “Error: The changes could not be applied (error code 1).” why is that? I left every thing as the default.
