ap90033 Posted September 12, 2024 Posted September 12, 2024 I have a total of 8- 10TB Drives and 4 14TB Drives. Currently in a 2 Parity Unraid Array with 57TB of data. I am trying to convert to ZFS but without losing data. Currently I am working on moving (with unbalance) the data to as few drives as possible. Then my plan is to create multiple vdevs for zpool. I am trying to have around the same amount of space (108TB) but not put the pool in worse shape as far as risk that it currently is in. Any suggestions? Quote
JorgeB Posted September 12, 2024 Posted September 12, 2024 If you are on v7.0.0-beta you can use the mover to empty a drive, then format and repeat, but note that currently there is a known write performance issue with zfs and the array, it doesn't affect pools. Quote
ap90033 Posted September 12, 2024 Author Posted September 12, 2024 Is the beta stable? Also, I would prefer to use pools then due to performance. I was thinking of setting up (2) 4 Drive 10TB RaidZ1 vDevs and (1) 4 Drive 14TB RaidZ1 vDev for a pool. Would that be the best way to go for protection and performance balance do you think? Quote

I think that's an OK layout, but a resilver will take some time with large disks like that, so make sure you have adequate backups Quote
ap90033 Posted September 13, 2024 Author Posted September 13, 2024 Well i was planning on using unbalance to move data off of 5 drives, create a udev and move everything I can to it, then create another 5 drive udev in same pool. This would give me enough space to move all data over then take the final 4 drives (14tb) and make another udev. I have a couple 10tb drives that I can add to make this work. Thoughts? I attached a diagram of my plan. I was thinking three total vdevs all RaidZ1... UNRAID PLANNING.pdf Quote
JorgeB Posted September 13, 2024 Posted September 13, 2024 Unraid requires that all the vdevs be the same width (and type), so you cannot have one with 4 disks and the others with 5. Quote
