I'm looking to finally set up unRAID, and I've got some questions.
My current volumes look like this (Windows software raid):
Volume A - 2 disk mirror, 4TB usable:
Disk 1 - 4TB
Disk 2 - 4TB
Volume B - 2 disk mirror, 4TB usable:
Disk 3 - 4TB
Disk 4 - 4TB
These was set up 5 years apart, so it made sense at the time to do it like this. For various reasons, I'd like to only have 2 data drives and 2 parity drives.
As I understand it, the array will continue to work even if both data drives fail, and only the 2 parity drives are working. So it doesn't matter which physical drive is assigned what role (I have 2 new drives, 2 old).
Does it make sense to set up the drives in this order?:
Remove disk 2/4 from my Windows machine, they will hold the only copies of my data.
Install unRAID, preclear disk 1/3.
Set up a new volume with 1 data drive, and 1 parity drive.
Connect disk 2.
Use the "Unassigned devices" plugin to mount disk 2 (NTFS file system).
Move data from disk 2 to my unRAID array. (How do I do this, can I do it natively in unRAID, or do I need the Krusader plugin?)
Preclear disk 2
Expand my array (It will now have 2 data drives, 1 parity drive).
Connect disk 4, mount it, and move data to my array.
Preclear disk 4, set it up as 2nd parity drive.
I'll have to migrate Plex and qBittorrent to Docker. Plex should be relatively easy, but I can imagine having to add all torrents in qBittorrent manually since I'm moving from Windows to Docker.
To sum up:
Does it make sense to move my data in this order?
How do I set up the filesystem on the individual disks. Is everything done by setting up shares, or can I manually create folders?
Do I use "Unassigned devices" and "Krusader" plugins to move data to my array? I don't want to accidentally loose anything...
Is there a way to migrate torrents from qBittorrent Windows to Docker?
Can I see the GUI of programs running in Docker? For example, how do I see the qBittorrent UI? (apart from the Web UI).
Is there a popular way of doing backups? I'm considering running backups from a Windows machine (network or VM) to be able to use SpiderOak.
How does fan control on a normal pc case work? Is there a way for unRAID to control fans connected to motherboard fan connections? Or perhaps I will need to use a dedicated fan controller and USB-passthorugh to a VM.
Anything else I must know about before installing?
Thanks for any and all feedback!
