I think this is my first post here! The conversion to unRAID has been smooth. This is such a great community and so much documentation. I did see threads.on this I just wanted to make sure my plan was solid. I currently have an 8 disk array with 7D+1P. I am going to pull out at least 2 maybe 3 smaller disks and replace with 1 larger drive, so I'll have 5 or 6 data disks and 1 parity. All of my internal SATA ports are full. I was thinking I can pull out one of the data drives to be replaced. Preclear the new drive, let it rebuild from parity. Then shut down dockers and mover then use unbalance to move data from the other drive I will remove. And then remove that drive from the array and run a parity check/write/rebuild... Profit? I understand unbalance is pretty much just a gui for rsync but I've successfully used it in the past and I don't have to learn more command line lol Sent from my Pixel 6 Pro using Tapatalk

This is the Unraid default for disks, parity partition starts on sector 2048, it means it was partitioned outside Unraid, recently Unraid started supporting that starting sector for SSDs so it doesn't complain, but because of that there are a few less sectors available, to resolve this you'd need to wipe that partition then let Unraid repartition it and re-sync parity.

Replacing multiple disks in array with 1 larger disk.

So I am looking to do something very similar to this thread and I just want to make sure I am interpreting it correctly.

I want to retire all 3 6 TB disks and replace them with the 18 TB and 12 TB disks.

So I believe my order of operations is.

1) Replace 1 6 TB disk with the 12 TB disk, rebuild from parity.

2) Replace 1 6 TB disk with the 18 TB disk, rebuild from parity.

3) Use unbalance to move data from the final 6 TB disk to the 18 TB disk.

ChatNoir said "use the New Config tool to rebuild parity with only the drives you want to keep (we can discuss this later)"

This is the piece I dont understand. Any clarity is helpful. Thanks.

After the last 6TB disk is empty do a new config without it and resync parity.
