Replacement Build

[Bruce Wilfong]

Hello all,
I currently have a freenas box using 2 Zpools. One pool is 4 x 4TB drive, and the other is a mixture of 6 x 1TB drives for a total of 10 drives. My PC is current AMD CPU and basically odd PC parts. I am upgrading this system to:

Intel Xeon Processor E3-1231V3B 3.4 4 LGA 1150 (BX80646E31231V3)
Supermicro X10SL7-F uATX DDR3 1600 LGA 1150 Motherboard
2 of SAMSUNG Samsung DDR3-1600 8GB1Gx72 ECC CL11 Server Memory / M391B1G73QH0-YK0
Corsair Power Supplies , RMX 850W CP-9020093-NA

I would like to lessen the total number of drive to 6 (since the mother motherboard has 6 ports), by replacing the six 1TB drives with two 4TB drives and coming the two pols into 1 Zpool. I just need some help figuring out how to accomplish this.

Thanks

If you created a 6 disk RAIDz2 volume consisting of 4x4TB + 2x1TB drives, the 4TB drives will effectively be seen as 1TB drives. If you were to replace the 1TB drives with 4TB drives, you would reclaim the unusable space on the original 4TB drives and your pool would automatically expand.

Another option, would be to stripe three sets of mirrors (2x4TB + 2x4TB + 2x1TB).

I would go with the mirrored option as well.

Are you planning on using the existing case ? If so, you are not limited by the number of SATA ports on the motherboard. You can always add a PCIE HBA card to handle more drives than the number of SATA ports on the motherboard.

I can flash the motherboard to IT mode to use the 2 SATA 6Gb and 4 SATA 3Gb in addtion to the 6 SAS ports. But I think I am just going to copy over my current data and then blow everything away to start fresh going with 8x 3TB drives in RaidZ2.
