Hello,
I’m thinking about the best migration strategy of my TrueNAS Scale Server.
I currently run TrueNAS-SCALE-23.10.2 on the following hardware and I have tested the new parts with Dragonfish Beta.
Currently 16TB of Data to be migrated
- Asrock Rack X470DU with 2700X
- 4x32GB RAM ECC
- 750W Power Supply
- Asus Hyper M.2 PCIe3.0 V2
- 250GB NVME for OS
- Intel X710-DA2
- 4x 16TB Toshiba as striped mirror
- 2x Micron 7300 Pro 960GB mirrored as special vDev (metadata) in Asus Hyper M.2
- no L2ARC, no SLOG
- 2x Micron 7300 Pro 960GB mirrored for VMs in Asus Hyper M.2 (very power hungry)
“New Server parts”
- Gigabyte MC12-LE0
- Ryzen 4650G
- 4x 16GB ECC
- 4x Optane P1600X
- HP H220 HBA
- 10x 4TB SATA & SAS HDDs
- Intel X520-DA2
- Asus Hyper M.2 PCIe 4.0
New Main Fileserver (as Gigabyte with 4650G is less power hungry) - main Objective: power efficient Fileserver with fast access via 10Gbit with SMB:
*TNS Dragonfish - pool needs to be rebuilt
- Gigabyte MC12-LE0
- Ryzen 4650G
- 4x32GB RAM ECC
- 750W Power Supply
- Intel X710-DA2
- 4x 16TB Toshiba as striped mirror
- 250GB NVME for OS
- 2x Optane P1600X mirrored as special vDev (metadata) in Asus Hyper M.2 PCIe 3.0
- no L2ARC, no SLOG planned
New Backup Server:
- TNS Dragonfish
- Asrock Rack X470DU with 2700X
- 4x 16GB ECC
- HP H220 HBA
- 250GB NVME for OS
- 10x 4TB SATA & SAS HDDs & RAIDZ2
- Intel X520-DA2
As you can see, I intend to swap of platforms - my current thinking for migration:
- setup server with Gigabyte MC12-LE0 and 10x 4TB SATA & SAS HDDs & RAIDZ2
- backup all data from current server (replication?) - advise requested
- Set up new backup Server with X470D4U and add 10x 4TB SATA & SAS HDDs & RAIDZ2 pool
- If all data are present - rebuilt new main fileserver (as I rebuilt with Optane drives and I need to rebuilt - this time with correct small block size (8Kb)) - during that time - my only copy of the data is on the new backup server
- Syncronize data from backup server to main server - advise requested
Does this workflow makes sense? Where are the major risks
Thank you for your input
