Hello, All

We are using ZFS7320 storage with 1 disk shelf(DE2-24C) and Shelf consist of 20 drive(3TB SAS2 * 20EA).

The Pool is just one with 20 drives(single parity, narrow stripes).

If I add 1 more disk shelf using different capacity disk drive(4TB SAS2 * 20EA),

Is it available to add existing pool inspite of disk capacity difference?

If yes, Could you please let me know RAID Stripe method when we add/mix to existing pool with different size drive.

Incase of other storage, If we mix the disk drive to make raid group(RAID1/RAID5), Only can use/make a logical volume according to small disk drive size.

Howdy, Stranger!
