I've just completed migrating from drivepool and now I want to use the largest drive as a parity.

I've read the faq for removing a drive https://lime-technology.com/wiki/index.php/FAQ_remove_drive

and was wondering if I have to exclude the drive I'm removing from the share before I copy the files from the disk to the share or not?

You need to provide more details. Not sure what you are trying to achieve here.

 

And whatever you do, do NOT copy data between disk and share.

I was running drivepool on windows with 2x file protection. My drivepool was mostly full so I bought a 4tb drive and a copy of unraid, formatted the 4tb as disk 1 and began moving my files over using Unassigned Devices and mc. When I completed the transfer from a drivepool disk I added it to the array and formatted it. now I have completed moving all my files from drivepool and have added all the disks to the array. My new 4tb disk is the largest one so I want to use it as parity. my array has enough room to hold all the files without the 4tb, I just need to remove it from the array without losing all the files it is currently holding.

 

I have moved the docker img from disk 1 to disk 3, now I need to move the files off of disk 1 so I can make it the parity disk.

 

I found this guide

I believe the unBalance plugin will do what you want, with minimal learning invested.

 

If you are relatively computer savvy, then I would invest the time in figuring out unRaid's user share system vs disk shares, and use mc from the terminal to do what you want. As long as the source of the move is /mnt/disk1 and the destination is /mnt/diskX where X is the disk number you want to move the files to you are golden. Just don't ever have /mnt/disk on one side of mc and /mnt/user on the other. It's too easy to erase data that way by moving it onto itself and zeroing it out. Every root folder on every /mnt/diskX is a user share, so to move the files to another disk, just move the root folder from disk to disk. Don't even look in /mnt/user until you understand why it works and what it's doing.

 

After you have all the data copied where you want it on the smaller disks, then you can set a new config and assign the 4TB to parity and the rest of the disks to whatever number you want.

thanks!
