pharpe Posted March 3, 2023 Share Posted March 3, 2023 (edited) I currently have a Proxmox server with three 8 TB drives in an ZFS Raidz1 container with about 10 TB of data on it. I am building a new server and I want to use Unraid as the OS. I would like to use the drives in my old server in the new Unraid but I need to figure out how to keep the data. In addition I have these empty drives available to use in the new Unraid server: 4 - 4 TB HHDs 2 - 1 TB SSDs 4 - 512 GB SSDs From what I have read I think this is the best plan but wanted to get feedback. Fyi I am new to Unraid but have a moderate background in linux, proxmox, and docker. Plan to setup Unraid with the following Parity - 4 TB HHD Disk 1 - 4 TB HHD Disk 2 - 4 TB HHD Disk 3 - 4 TB HHD Cache 1 - 512 SSD Cache 2 - 512 SSD Cache 3 - 512 SSD Cache 4 - 512 SSD According the this disk calculator , https://unraid.category5.tv/, that should give me about 10.88 TB. I could then copy all files off my old server over to the new Unraid server. At that point I would shut the old server down and move the 3 - 8 TB drives over to the new server. If I understand correctly I can replace the 4 TB parity drive with one of the 8 TB drives (this is what I'm uncertain about). I can then add the other two 8 TB drives into the array as additional disks. End result looking like this: Parity - 8 TB HHD Disk 1 - 4 TB HHD Disk 2 - 4 TB HHD Disk 3 - 4 TB HHD Disk 4 - 4 TB HHD Disk 5 - 8 TB HHD Disk 6 - 8 TB HHD Cache 1 - 512 SSD Cache 2 - 512 SSD Cache 3 - 512 SSD Cache 4 - 512 SSD Questions: Is what I'm thinking possible? Is it the best/easiest/safest method to get to the end goal? Does having four 512 GB cache drives even make sense? I also have two 1 TB SSDs that I can use somewhere. Was thinking of creating a second array, mirroring these drives, for fast storage to host SQL DBs. Can Unraid do this? Edited March 3, 2023 by pharpe Quote Link to comment
