Hey. I've tried googling this, but I'm not exactly sure what to google (or how to title this post), so I try asking here.

 

I've played around with the trial version on a spare computer, and decided to make a server. I currently have an 8 TB disk (disk1) in my Windows PC with data on it. I have another 8 TB disk (disk2) on the way, that I intend to use as parity. (Disk1 is BarraCuda, disk2 is Exos).

This is my plan:

• Format disk2 and include it in the array
• Copy data from disk1 to disk2
• Format disk1 and include it in the array
• Copy data from disk2 to disk1
• Make disk2 parity disk

 

Is this possible? Or is there a better way?

 

I also have a 500gb disk currently in the unraid, not sure if that is important info.

I would probably just add disk1 as the parity drive in the 3rd step and skip the last 2 steps.

 

Not sure about the 500gb disk.    You could either keep it as an array disk, or alternatively use it as a ‘cache’ pool.   Does it currently have data on it that needs to be kept?

I forgot to include in my initial post that the reason I plan on doing it this way, is because the disk2 is enterprise disk, while disk1 is consumer grade(?) I've read that it's better to have the enterprise one as parity.

 

The 500gb has some data on it, but nothing important. I plan on keeping it, just because I don't have any other use for it. I'm also going to install a 2 TB NVMe to use as cache, forgot to include that as well.
